摘要
利用小比例尺模型的振动台试验定量估计建筑结构的地震反应和抗震性能,是我国抗震试验研究的新动态。本文就动力相似律在小比例模型试验中的应用作了分析,着重探讨了结构非线弹性反应的模拟问题,其内容包括:模型设计的一致相似律,忽略重力模型和欠人工质量模型在非弹性阶段的试验误差,以及在不同变形条件下考虑材料非线性的相似律确定等问题。
Using small scale models on shaking table test to estimate quantitatively the earthquake research on earthpuake response and seismic behauior of building structures is a new trend of research on earthquake resistant test in our country. In this paper, the application of dynamic similitude kw in small scale model test is analyzed. The similitude problems of nonlinear elastic response of the structure are investigated emphatically, which includes the consistent similitude kw in model design, experimental error in the model by neglecting the gravitational force and not enough artiticital mass in the non - elastic stage, as well as the determination of wimilitude law by considering the material non - linearity under difterent conditions of deformation.
