摘要:
为了对料石墙体缩尺试验方法进行探究,开展了足尺试件和2种不同缩尺试件的水平低周反复荷载试验研究,通过对比破坏特征、各阶段剪应力和水平位移角以及抗震性能等指标,对2种缩尺模型进行分析.试验结果表明:采用墙体缩尺、砌块足尺的缩尺模型在破坏特征、各阶段剪应力和水平位移角以及抗震性能方面,除滞回性能和耗能能力略有不同外,其余均与足尺模型试验结果较为接近,该缩尺模型基本可以反应足尺模型的特性;而严格按照相似比理论的缩尺模型,在破坏特征和各阶段剪应力方面与足尺模型试验结果较为接近,但由于砌块表面粗糙程度的不同,其在水平位移角和抗震性能方面与足尺模型有较大差距.
Abstract:
Horizontal cyclic loading tests were carried out on a full scale specimen and two reduced scale specimens to find out the appropriate reduced scale model of stone masonry walls. The failure mode, shear strength, horizontal displacement angle and seismic behavior were analyzed. The experimental results show that except for the hysteretic performance and energy dissipation capacity, the failure mode, shear strength, horizontal displacement angle and seismic behavior of the model with full scale block but reduced scale wall are close to those of the full scale model. This reduced scale model can basically represent the characteristics of the full scale mode. As for the reduced scale model strictly accordant with the theory of similarity, the failure mode and shear strength are close to those of the full scale model; however, because of the difference on surface roughness of block, the horizontal displacement and seismic behavior are totally different from those of the full scale model.
