底部框剪上部混凝土砌块结构在水平地震作用下的动力响应
|
摘要
进行了底部2层框剪上部6层混凝土砌块砌体房屋1/8比例模型振动台试验。以El Centro波、Taft波和场地波为输入地震波,分6度、7度区多遇烈度、基本烈度及罕遇烈度地震三阶段试验,考察了模型在各阶段试验的地震反应。在试验前和各阶段试验后均对模型进行了白噪声扫描试验,考察该模型的频率变化规律。试验结果表明:当输入地震波强度达到7度中震强度时,底部框剪层开始开裂,结构变形由弹性段进入弹塑性段;该结构能满足7度区的抗震设防要求。
In this paper the shaking table test of the 1/8 scale model of six storey concrete block masonry building supported by frame-shear wall at the first two stories was studied. The test was conducted, inputting the El-Centro earthquake wave, the Taft earthquake wave and the site earthquake wave in three intensities, i.e. the seismic frequent intensity, the seismic fortification intensity and the seismic seldom intensity for 6 and 7 degree seismic region separately. The white noise scanning tests were conducted before the shaking table test and after its every stage to measure the frequency of the model. Analysis of the experimental results indicates that the crack started appear on the bottom frame-shear wall, and the deformation changed from elasticity to elastoplasticity, when the earthquake wave intensity reached the seismic fortification intensity for 7 degree seismic region, and the buildings can satisfy the requirement for the 7 degree seismic region.
