    摘要: This paper describes the seismic rehabilitation of a Chinese traditional palace architectural style
    building with irregular hybrid structure, constructed early 1980s in Taiwan. The evaluation with
    strength design adaptation, linear dynamic procedure and current nonlinear static procedure were
    employed. Both equivalence elastic response spectrum and inelastic response spectrum of push over
    analysis for the capacity spectrum rehabilitation of building were included. The ground motion at the
    dependent site of March 31, 2003(331 EQ) and September 21, 1999 (921 EQ) are also selected for
    linear and nonlinear response history analysis. Procedures to member model are : (1) bending
    moment in hinge element at beam ends; (2) bending-shear forces in beam model as elastic element
    with hinge elements; (3) shear forces, axial forces and bending moment in nonlinear beam-column
    element with axial force-bending moment interaction (P-M-M) including three type hinge modes as
    bending, bending-shear, and shear; (4) equivalence column element in shear wall hinge elements; (5)
    truss members as elastic elements and (6) nonlinear inelastic dampers with axial forces in fluid
    viscous device( FVD ) elements for enhancing the building seismic capacity. The capacity spectrum
    of the structures were developed base on the existing concrete strength, reinforce bars, steel and size
    of members as as-built drawings shown and investigation reports on the structure early 2005. The
    seismic performance level of the buildings are defined as essential hazardous object and it should be :
    (1) beyond life safety of the structure for maximum considered earthquake at 2500-year return period
    (2% in 50 years, EPA = 0.32g); (2) immediate occupancy of the structure for design earthquake at
    475-year return period (10% in 50 years, EPA =0.24g) and (3) full operational with the structure
    within yield limit state for serviceability earthquake at approximate 72-year return period. The results
    show that the proper arrangement and use of fluid viscous devices (FVD) in seismic enhancing of the
    structure including its pile foundations will attain this seismic performance level. It is also shown that
    these seismic evaluation procedures are practicable for the irregular hybrid structures.
