混凝土灌芯玻璃纤维增强石膏墙板的简化计算
|
摘要
利用多垂直杆元模型建立了混凝土灌芯玻璃纤维增强石膏墙板的计算模型,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.利用该模型对满灌混凝土石膏墙板和隔孔灌混凝土石膏墙板试验结果进行了分析,计算曲线和试验曲线比较一致,表明该模型不仅力学概念清晰,计算简单,而且具有较好的计算精度,便于在整体结构的计算中使用.
The calculating model for concrete-filled glass fiber reinforced gypsum wall panels was established by using the multi-vertical-line-element model.The method for calculating the force-displacement skeleton curves of verti-cal-line element and shear element was then proposed.The test data of concrete filled panels and partial concrete filled panels were analyzed based on this model.The calculated curves agreed well with the experimental ones,which proves that this model has the advantages of clear mechanical conception,simple calculation and relatively good accuracy,and is convenient for calculating integral structure.
