密肋轻钢龙骨复合墙体的抗剪性能
|
摘要
密肋轻钢龙骨复合墙体是密肋结构体系中的一种新型墙体构件形式,具有现场施工连接方便,易于工厂成批化加工等优点.为了研究其墙体的承载性能,对1/2比例密肋轻钢龙骨复合墙体与普通密肋复合墙体进行了低周反复荷载试验,对比研究了密肋轻钢龙骨复合墙体的破坏形态、钢骨应变变化规律、抗剪承载力影响因素及其实用计算公式等.试验结果表明,两者的破坏形态基本一致,轻钢龙骨复合墙体的承载力明显高于普通密肋复合墙体.最后结合试验数据给出了密肋轻钢龙骨复合墙体的开裂荷载与极限抗剪承载力的建议计算公式.
Multi-ribbed composite wall with light-gauge steel was a new wall with the benefits of easily construct connection、convenient factory cure and so on.In order to study the bearing capacity of multi-ribbed composite wall,based on experiment of two 1/2 scare composite walls,one of which was general composite wall and the other was composite wall with light-gauge steel,under low frequency cyclic and reversed lateral load,failure type and earthquake behavior about bearing capacity on them were studied.The results show that both of them have the same failure type,but the bearing capacity of the composite wall with light-gauge steel is better than the general composite wall.According to the experiment statistics,calculation formulae for cracking load and shear bearing capacity of multi-ribbed composite wall with light-gauge steel were given.
