本文讨论在水平反复栽荷作用下多孔砖(KP-1型)墙在其平面内的侧移和刚度;在86个无筋多孔砖墙及73个配筋多孔跨墙片试验的基础上,研究了多孔砖墙的侧向变形,包括多孔砖砌体的弹性模量、竖向压应力对侧向变形的影响;提出了砖墙侧移和刚度计算公式变形验算公式及限值。按建议公式所得的计算值与试验值基本吻合,可供设计研究参考。
This paper discusses the lateral displacement and stiffness of perforated brick (KP-1 type) walls in horizontal planes under the effect of repeated horizontal loading; based on the experiments of 86 non-reinforced perforated brick walls and 73 reinforced spanning porous wall sheets, The lateral deformation of perforated brick walls was studied, including the elastic modulus of perforated brick masonry and the effect of vertical compressive stress on lateral deformation. The deformation checking formulas and limit values of the calculation formulas for lateral displacement and stiffness of brick walls were proposed. The calculated values obtained from the proposed formula are basically consistent with the experimental values, and are available for reference in design studies.
