摘　　要：通过实测复合墙板试点工程结构的动力反应,获得了结构的自振频率、振型和阻尼比等模态参数。提出一种适用于工程界广泛采用的SATWE建模的材料等效简化方法。采用此方法对试点工程进行的分析计算表明,计算和实测的基本振型吻合较好。对结构进行的地震反应分析结果表明,结构抗震性能良好。The natural frequency, modal shape and modal damping ratio of the typical structural of composite wallboard （rapid wall） system are got by dynamic behavior measurement. A method to simplify the composite wallboard to the equivalent is brought out for establishing the finite element model in SATWE, which is widely used in engineering design. Using this method, the analysis and calculation results for the typical structure indicate that the results of practical measurement about the fundamental modal accord with the computational ones basically. Finally, the anti-seismic capability of this structure is proved to be excellence by seismic response analysis.
