摘要
为科学评定新疆安居房屋的抗震能力,通过1/2大比例尺新疆安居房屋模型模拟地震振动台试验,研究设置构造柱与圈梁的新疆安居房屋模型在地震作用下的破坏特征以及地震反应。试验结果表明,在峰值加速度为0.1 g^0.3 g地震动作用下,模型处于完好状态。在峰值加速度0.4 g地震动作用下,模型墙体出现开裂。在峰值加速度1.2 g地震动作用下,墙体发生明显破坏但未倒塌,构造柱和圈梁基本完好。试验结果证实设置构造柱和圈梁是提高砌体房屋抗倒塌能力的一种有效措施,新疆安居房屋具有良好的抗震能力。
In order to scientifically assess the seismic capacity of economic housing buildings, shaking table test of an 1 ： 2 scale housing building model was carried out, in which the damage features and the seismic responses of the model with construction column and ring beam could be when the peak acceleration was 0. lg to 0.3g in the test. studied. It was found that the model was in good condition The masonry shear wall was cracked when the peak acceleration was 0. 4g and it was seriously damaged but not collapseed when the peak acceleration reached 1.2g. It is verified from the test that the constructional column and the ring beam are efficient to prevent the collapse of building during earthquake. Such kind of building shows good seismic resistant capacity.
