针对底层大开间组合墙房屋的特点 ,对模型房屋进行了子结构拟动力试验 ,测定其抗侧刚度 ,发现了抽柱对结构性能的重要影响。试验表明 ,底层大开间组合墙房屋具有良好的抗震性能。
Aiming at the characteristics of the composite house with a large open floor, the substructure pseudo-dynamic test was conducted on the model house and its lateral stiffness was measured. The important influence of the draft column on the structural performance was found. Experiments show that the combination of low-rise house with a large wall has good seismic performance.
