为提高砌块建筑的整体性和抗震性能,本文在分析了砌块墙体抗剪特性的基础上,提出了采用竖向整体预应力的有效措施,来提高砌块建筑的整体性和抗震性,使用钢量少、材料省、造价较低、施工也较简便,以利于地震区和高层建筑上推广应用。一、砌块墙体的抗剪特性砌块房屋的抗震性能,主要取决于砌块墙体的抗剪强度和变形性能。从目前国内大量砌块墙体的抗侧力试验结果来看,尚未得出一致的结论。这是由于影响砌块墙体抗剪 In order to improve the integrity and seismic performance of block building, this paper analyzes the shear resistance of block wall and proposes effective measures to adopt vertical overall prestressing to improve the integrity and seismic resistance of block building. , The use of less steel, materials, lower cost, construction is also relatively simple, in favor of the earthquake area and high-rise buildings to promote the application. 1. Shear properties of block walls The seismic performance of block houses is mainly determined by the shear strength and deformation performance of block walls. From the results of the lateral resistance test of a large number of domestic block walls, no consistent conclusion has been reached. This is due to the effect of block wall shear resistance
