Development of a structural health monitoring platform for a building structure

Fri, 01 May 2026 04:05:31 GMT

title: Development of a structural health monitoring platform for a building structure abstract: Frequent earthquakes in Taiwan highlight the urgent need for reliable post-earthquake damage assessment. Advances in lightweight sensors, fast data collection, and wireless transmission make structural health monitoring (SHM) an effective tool for building safety. This study develops an SHM platform for a multipurpose public housing building, integrating seismic sensing, system identification, and building information modelling (BIM). A frequency-domain recursive hybrid genetic algorithm was applied to identify structural parameters for damage diagnosis. Seismic records were analyzed to capture time-varying dynamics, generate diagnostic reports, and compare results from different events. On the other hand, a rapid screening method using interstory drift angles provided preliminary assessments and supported warning signals. The platform includes three modules: (1) BIM visualization of structure and sensor data, (2) real-time monitoring with quick damage screening, and (3) automated reporting with stiffness-based indicators for repair or retrofit decisions. The framework shows the potential of combining SHM and BIM to strengthen seismic resilience and the life-cycle management of buildings.

Subseasonal Typhoon Precipitation Forecast in Taiwan Area Using the ECMWF Reforecasts: Forecast Verification and Application

Mon, 20 Apr 2026 04:05:27 GMT

title: Subseasonal Typhoon Precipitation Forecast in Taiwan Area Using the ECMWF Reforecasts: Forecast Verification and Application abstract: The main objective of this study is to assess typhoon precipitation forecast skill on the subseasonal timescale. The 20-year reforecasts from the ECMWF 46-day ensemble (ENS) are utilized to compare with gridded surface observations in Taiwan. The analysis focuses on the dates when typhoons affect Taiwan (117-129°E and 19-28°N). 15 ENS grids around Taiwan area are used with the grid size of 0.8 x 0.8 degree. Historical rainfall observations are provided by the Central Weather Administration (CWA), which the observations from the surface stations are interpolated into a resolution of 1km x 1km grid box. A comparison between the ENS forecast data and gridded CWA rainfall observations is performed by searching the optimal percentile rank (PR) of gridded CWA rainfall that has the smallest mean difference against the ENS data. The result reveals that the ENS can somewhat capture the rainfall contrast between the mountainous area and plain area, despite its relatively lower horizontal resolution. However, the difference between ENS rainfall forecasts and surface observations significantly increases for the forecasts beyond 72 hours, due to the model's coarser resolution and typhoon track forecast errors.The ENS typhoon track forecast errors in weeks 1-4 are analyzed by comparing the ensemble vortex tracks with the JTWC best tracks. The track forecast error is decomposed into the along-track (AT) and cross-track (CT) components. The analysis result shows negative mean AT errors, indicating slower translation speed biases in the model. The mean AT errors could reach up to 400 km for the 168 h forecasts after TC formations.Given the significant typhoon track forecast errors, using the raw ENS rainfall forecasts for the operational TC forecasting/outlook become challenging. In response, we have developed a statistical Quantitative Precipitation Forecast (QPF) model to predict typhoon rainfall, considering the track biases in the ENS forecasts. The forecast tools developed in this study will be integrated into CWA's subseasonal typhoon forecast system to support water resources management and disaster risk reduction.

Investigating the Impacts of the Large-Scale Environments on the Subseasonal Tropical Cyclone Forecast Skills Using the 46-Day ECMWF Ensemble.

title: Investigating the Impacts of the Large-Scale Environments on the Subseasonal Tropical Cyclone Forecast Skills Using the 46-Day ECMWF Ensemble. abstract: This study utilizes the 46-day ECMWF ensemble forecasts to assess the subseasonal forecast skills of tropical cyclones (TCs) in the western North Pacific. The 20-year reforecasts from 2002-2021 are used to objectively detect TC formations and their subsequent tracks (Tsai et al. 2023). The evaluation of TC forecast skills is carried out by utilizing the TC strike probabilities in the 10-degree latitude-longitude boxes. The reliability diagrams (RDs) are utilized to evaluate the forecast skills in weeks 1-4, which show slight over-forecasting biases. The AUC (Area Under Curve) of the ROC (Receiver Operating Characteristic) curve is computed for week-1 to week-4 forecasts, which are 0.91, 0.85, 0.82, and 0.81, respectively. The impacts of the Madden Julian Oscillation (MJO), Boreal Summer Intraseasonal Oscillation (BSISO), and Western North Pacific Summer Monsoon (WNPSM; Wang et al. 2001) on the subseasonal TC forecast skills are investigated. In addition to the RD and ROC curve, the Precision-Recall (PR) curve is used to reduce the impact of imbalanced data. The preliminary results indicate that the subseasonal TC forecast skills are influenced by the large-scale environments. For example, TC forecast skills are better when the forecasts are initialized in MJO phases 6 and 7. More details about the impacts of MJO, BSISO, and WNPSM on the subseasonal TC forecast skills will be presented in the meeting. Finally, TC precipitation forecast skill in the subseasonal timescale will also be evaluated to explore the potential application for the water resources management in Taiwan.

Monitoring Global Tropical Cyclone Activities on Subseasonal Timescale Using the CWB TC Tracking System

Mon, 20 Apr 2026 04:05:23 GMT

title: Monitoring Global Tropical Cyclone Activities on Subseasonal Timescale Using the CWB TC Tracking System abstract: A real-time tropical cyclone (TC) activity monitoring system has been developed at Central Weather Bureau (CWB) to objectively detect TCs in the 16-day NCEP GEFS (Global Ensemble Forecast System) since 2008. This system has been upgraded in 2020 by extending the forecast lead-time to four weeks. The new system, CWB TC Tracker 2.0, has integrated the forecasts from multiple global ensemble models. In addition to the NCEP GEFSv12, the real-time forecasts from the 46-day ECMWF ensemble (ENS), NCEP Climate Forecast System (CFSv2), and the CWB 1-tier climate forecast model (CWB1T1) are included. The forecasters from multiple forecast agencies are jointly using the CWB TC Tracker 2.0 as their TC forecasting tool in weeks 1-4. The development of the CWB TC Tracker 2.0 will be introduced. The weeks 1-4 TC forecast skills in the western North Pacific are also evaluated using the ENS and the GEFSv12. As shown in the preliminary verifications using the 20-year reforecasts, promising forecast skills can be found in both ensemble models, especially in the week-1 and week-2 forecasts. The impacts of large-scale environments on TC activity forecasts are further investigated (i.e., summer monsoon, MJO, and ENSO). A spatial-temporal ensemble track clustering algorithm (Tsai et al. 2019) is implemented to group similar ensemble vortex tracks for the track verifications and the false alarm detections. More details about the subseasonal TC forecast applications and verifications using the CWB TC Tracker 2.0 will be presented in the meeting.

title: 沸石咪唑酯骨架ZIF-8衍生碳材料應用於電容去離子(CDI)系統 abstract: 電容去離子(CDI)是透過對電極施加電壓的方式，利用電極材料之電雙層吸附機制，達到水質淨化的電化學技術。金屬有機框架(Metal Organic Frameworks, MOF)則由有機配體和金屬離子組成，根據不同的合成方式和材料成分，能夠形成多種組合，呈現極高的可塑性。沸石咪唑酯骨架 (Zeolitic Imidazolate Frameworks, ZIF)為MOF之一種類，本研究採用的ZIF-8是以Zn為金屬源，在溶劑中生成咪唑或咪唑衍生物作為有機配體，具有MOF的結構，且克服熱穩定性及化學穩定性問題，同時ZIF-8易於控制晶格孔隙大小，應用靈活，可廣泛應用於不同領域。本研究以ZIF-8，經高溫碳化及活化後，作為 CDI 電極材料，電吸附水中鹽類離子，研究中將探討不同活化溫度對 ZIF-8 衍生碳材料之結構改變與電吸附效能評估。以SEM觀察ZIF-8衍生碳材料的表面型態，原始的ZIF-8顆粒約在40-90 nm，經800°C碳化後，ZIF-8_800c的顆粒介於40-110 nm，ZIF-8_800c的表面受到破壞，且顆粒間有明顯團聚。進一步以900°C活化，ZIF-8_800c_900a的顆粒尺寸稍微下降至40-80 nm，但顆粒團聚現象仍然顯著。 ZIF-8材料的結晶狀況，原始的ZIF-8具有晶格面(011)、(002)、(112)、(022)、(013)、(222)、(114)、(233)、(134)、(044)等特徵峰。經過高溫800°C碳化和900°C活化後，原始ZIF-8材料的特徵峰消失，材料轉變為非結晶狀態的衍生碳材料。以循環伏安法(Cyclic Voltammetry, CV)觀察到ZIF-8碳化與活化後，比電容量可明顯提升。在掃描速率為1 mV/s時，原始ZIF-8的比電容值僅為6.7 F/g，經過800°C碳化處理的ZIF-8_800c可增加到55.2 F/g，進一步經過900°C活化處理的ZIF-8_800c_900a的比電容值更提高至86.4 F/g，表明碳化和活化處理有助於提升材料的電化學性能，使其在CDI系統中表現更優越。

title: 流動式電極電容去離子(FCDI)系統移除工業廢水中之鉻(VI) abstract: 世界上的水資源需求量增加，但淡水卻無法如同需求量增長，因此如何獲得潔淨淡水是人類極需要解決的問題。電容去離子(Capacitive Deionization, CDI)為近年受到關注的新穎脫鹽技術，相較於傳統常採用的薄膜處理或熱處理技術，具有節能、易再生、無二次汙染等優勢。流動電極電容去離子 (Flow-electrode Capacitive Deionization, FCDI)是電容去離子(Capacitive Deionization, CDI)系統的新型態系統，具有諸多優勢，包括：去除效率高、可處理高濃度溶液，並可實現連續脫鹽。FCDI技術為使用流動式的懸浮電極材料，相較於傳統CDI系統之固定式電極，FCDI系統可以連續移除水溶液中鹽類離子，不會因電極再生步驟而中斷離子去除，適合處理高濃度鹽水濃度，且有系統易於放大實廠化之優勢。本研究測試 FCDI 系統於 4 種不同重鉻酸鉀濃度 (50, 100, 500, 1000 mg/L)之脫鹽表現，以短流封閉系統(Short-Circuit Closed, SCC)操作 2 小時，流動電極材料為 5 wt%活性碳，研究顯示 FCDI 去除重鉻酸鉀的效率隨著重鉻酸鉀濃度提高而提升，去除效率分別為95.2%、93.0%、96.5%與97.2%，平均脫鹽速率(Average Salt Removal Rate, ASRR)則是於重鉻酸鉀濃度為 100 mg/L 時，有最高的 ASRR，可達 3.1*10-4 mmol/cm2 /min；但就充電效率(charge efficiency) 與能源消耗(energy consumption)而言，於重鉻酸鉀濃度為1000 mg/L 時，擁有最高的充電效率(98.9%)與最低的能源消耗(21.4 kWh/mol)。本研究證實了以流動式電極電容去離子系統移除含鉻工業廢水的可行性，FCDI系統以重鉻酸鉀濃度為1000 mg/L時，具有高去除效率、高ASRR、低能耗及具有良好的選擇性，之後將再深入研究FCDI對移除不同價數Cr (Cr(III)或Cr(VI))的效能。

沸石咪唑酯骨架材料(ZIF-8)衍生碳材料應用於電容去離子(CDI)技術

Thu, 20 Mar 2025 04:12:21 GMT

title: 沸石咪唑酯骨架材料(ZIF-8)衍生碳材料應用於電容去離子(CDI)技術 abstract: 電容去離子技術(Capacitive Deionization, CDI)，其原理為施加低電壓(一般低於2.0 V)於成對電極之間，離子於電場驅動下，移動至帶相反電荷的電極上並被儲存在電極材料的電雙層(Electrical Double Layer, EDL)中，達到去除離子的目的。金屬有機框架(Metal Organic Framework, MOF)是一種具有良好離子吸附性能的奈米多孔材料，由金屬離子和有機配位基組成，其家族之一的沸石咪唑酯骨架(Zeolitic imidazolate framework, ZIF)中的ZIF-8材料，具有MOF的結構，且擁有特殊的熱與化學穩定性，ZIF-8易於調控晶格孔隙大小及性能，可廣泛應用於不同領域。本研究利用ZIF-8材料，經高溫碳化及活化後，將ZIF-8衍生碳材料應用於CDI系統，研究中探討碳化溫度(800oC與 900oC)對ZIF-8衍生碳材料之結構改變與電吸附效能評估，並將CDI系統中表現較好之碳化溫度衍生碳材料，進一步於900oC活化，藉以提升孔洞分佈，再將其應用於CDI系統。以(X-ray diffraction analysis, XRD)分析ZIF-8材料的晶格結構，原始的ZIF-8具有晶格面(011)、(002)、(112)、(022)、(013)、(222)、(114)、(233)、(134)、(044)等特徵峰，表示為高結晶度純相ZIF-8，經過高溫 800oC或900oC碳化後，原始ZIF-8材料的特徵峰消失，顯示ZIF-8材料轉變為非結晶狀態的衍生碳材料。以循環伏安法(Cyclic Voltammetry, CV)觀察到ZIF-8碳化後，比電容值顯著提升，由4.73 F/g提高到85.12 F/g (900oC碳化)，表示碳化後衍生碳材料擁有優異比電容量，有利於應用於CDI 系統之電吸脫附。ZIF-8_24hr_800c於 CDI 系統有較佳的電吸脫附表現，平均電吸附容量為5.54 mg NaCl /g，由此可知ZIF-8_24hr_800c為具潛力之碳材料。目前正致力於將ZIF-8_24hr_800c碳化前加入單寧酸，先刻蝕再以活化劑KOH於900oC活化，預期可優化ZIF-8碳化後材料之孔洞分佈，提升應用於CDI 系統之效能。

System Identification and Damage Assessment of Benchmark Model H

Thu, 20 Mar 2025 04:12:12 GMT

title: System Identification and Damage Assessment of Benchmark Model H abstract: Most of the existing buildings available for damage assessment are slightly or severely damaged, and these data may not be sufficient to establish damage indicators. To solve this problem, the experimental method is used to simulate different damage states, followed by identifying the parameters of the associated damaged structure. Consequently, damage indices that describe the degree of damage can be computed using the identified parameters, and then the threshold values of different damage states can be reached afterward. In this paper, the system identification method, called the hybrid genetic algorithm, is used to analyze the measurement from the shaking table test of a series of 3-story steel frame structures, called the benchmark model H constructed in the NCREE. This series of tests tries to simulate different damage states. In fact, structural models are a series of structures simulating various damage states by varying the numbers of diagonal bracings on both sides of x direction. The dimension of the structure is 3m in the longitudinal direction and 2m in the transverse direction. The shaking table test is carried out in the sequence from Full Bracing (FB) in the x direction to the bare frame. From Case1 to Case3, the vertical diagonal bracings of the outer side are removed one by one from the first floor to the third floor in the x direction. In this way, eccentric structures with varying degrees of damage can be simulated. Finally, all diagonal bracings in the x direction are removed, leading to a Bare Frame (BF). With the change in the dynamic parameters of the elastic system under earthquake, the damage assessment method is applied to determine the degree of damage and the location or floor of damage.

Study on the Seismic-induced Lateral Spreading along the Waterfront for Taipei Basin

Thu, 20 Mar 2025 04:11:51 GMT

title: Study on the Seismic-induced Lateral Spreading along the Waterfront for Taipei Basin abstract: Taipei Basin, the political and economic center of Taiwan, is underlain by soft alluvium soils that may be susceptible to soil liquefaction and the hazard of lateral spreading along the waterfront with sloping ground under earthquake strike. It is of substantial importance, therefore, to evaluate the damage hazard and risk of the infrastructure located at areas vulnerable to liquefaction and lateral spreading in the basin. The data of boring log, ground water table, and cross section along each river (Tamsui River, Keelung River, and Xindian River) in Taipei Basin are collected first. Two possible earthquake scenarios with four different intensities according to aseismic design code (including design earthquake and maximum considered earthquake) and the rupture of Shanchiao Fault (including moment magnitude of 7.1 and 7.5) are considered. The spatial damage index of liquefaction is interpolated by the method of Sequential Gaussian simulation. The multilinear regression (MLR) model published by Youd et al.(2002) is used to evaluated the displacement of lateral spreading. And then, the approach suggested by UNDRO (1979) that combines the hazard and vulnerability is used to evaluate the risk of lateral spreading along the waterfront and the sites of bridge. It is shown that the risk of lateral spreading induced by the rupture of Shanchiao Fault is greater than those from design earthquake and maximum considered earthquake of aseismic design code. The influence of characteristic earthquake of Shanchiao Fault on the lateral spreading displacement is the most important, and thus it is need to be included for estimating the risk. In the scenario of rupture of Shanchiao Fault, the risks of lateral spreading adjacent to the sites near the bank of Tamsui River are the largest, with Xindian River being the smallest. Thus, if the sites of building, bridge, earthworks, and lifeline are located along those waterfronts with high risk, the countermeasures against soil liquefaction and lateral spreading must be made to avoid the associated damages when earthquake occurs.
