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 multi-vertical rod-element model is used to establish the mechanics calculation model of concrete filled fiberglass-reinforced gypsum board, and the calculation method of load-displacement skeleton curve of vertical rod element and shear element is given.Using this calculation model, The modal analysis was carried out on residential buildings. The calculated period, mode and measured value are in good agreement with each other, which verifies the accuracy and validity of the calculation model. At the same time, the model is used to pushover residential analysis, In case of frequent earthquakes and rarely encountered earthquakes, it is proved that the inter-story drift angle can meet the requirements of elastic limit and elastic-plastic limit, and the model can be used to check the reliability of the actual engineering design .
