摘　　要：利用多垂直杆元模型建立了混凝土灌芯纤维增强石膏板的力学计算模型,并给出了垂直杆单元和剪切单元荷载-位移骨架曲线的计算方法.利用该计算模型,对一幢六层住宅进行了模态分析,计算出的周期、振型与实测值符合较好,验证了该计算模型的准确性和有效性;同时,还利用该模型对住宅进行了pushover分析,计算出结构在多遇地震及罕遇地震情况下的性能特点,证明该结构的层间位移角既能满足弹性极限的要求,又能满足弹塑性极限的要求,可以利用该模型校核实际工程设计的可靠性.The analytical model was established by using the multi-vertical-line-element model for concrete-filled glass fiber reinforced gypsum wall panels. Then the method for calculating the force-displacement skeleton curves of vertical-line-element and shear element was proposed. With the proposed analytical model,modal analysis was done for a six-storied house. The calculated periods and modes of vibration agreed well with tested ones,it proves the accuracy and validity of the proposed analytical model and the calculating method. At the same time,pushover analysis was carried out,the calculated performance points under frequent earthquake and very rare earthquake proved the story drift ratio can meet the elastic limit requirement and the elastic-plastic limit requirement,the proposed analytical model can verify reliability of an actual building design. In addition,it proves that this model has the advantages of clear mechanical conception,simple calculation and relatively good accuracy,it is convenient for calculating integral structure.
