[摘要]研究了在所有框架开口内填充砌体墙对框架刚度和强度的有利影响。对8个一层、一舱框架进行了失效试验；13个五层一间的框架；六座两层，三间房的钢筋混凝土框架。给出了试验结果，包括荷载-挠度关系、荷载-钢筋应变曲线、荷载-墙体应变数据以及墙体单元和框架单元的开裂信息。通过分析，计算了框架-框架系统在水平荷载作用下的响应。对小于这些裂纹的荷载的响应可以近似为悬臂梁的响应，后裂纹行为近似于带膝撑的框架的响应。砌体试件试验结果表明，墙体单元产生斜裂破坏的受力与砌体试件试验结果有关。砌体墙导致刚度的数量级增加，强度比未填充框架显著增加，但延性降低。(作者)
Abstract : The beneficial effects on frame stiffness and strength which result from providing in-filled masonry walls in all frame openings are investigated. Tests to failure were conducted on eight one-story, one-bay frames; 13 five-story, one-bay frames; and six two-story, three-bay reinforced concrete frames. The test results are presented, including load-deflection relationships, load-reinforcement strain curves, load-wall strain data, and information on cracking in both the wall elements and frame elements. Analyses are presented enabling the calculation of the response of the framewall systems to horizontal loadings. The response to loads smaller than those cracking can be approximated as that of a cantilever beam, and the post cracking behavior approximates the response of a frame with knee braces. The forces causing diagonal cracking and failure in the wall elements were related to the results of tests of masonry specimens. The masonry walls led to an order of magnitude increase in stiffness and a significant increase in strength over unfilled frames, but the ductility was reduced. (Author)
