摘要
为了解砌体墙变形机制的研究现状,对砌体结构外纵墙立面形状进行了实地调研,总结出了6种常见的砌体墙外立面形状并绘制了相应的受力简图。归纳了目前砌体墙变形机制的研究成果及砌体墙变形机制的影响因素。总结了砌体墙转动变形机制的研究现状及不足之处,进一步提出了砌体墙转动变形机制需进一步研究的现实意义。研究结果表明:砌体墙受力全过程的大部分阶段同时存在弯曲变形、剪切变形和转动变形,其中常常被忽略的转动变形对墙体的抗侧刚度影响较大;外立面形状等是影响变形机制的重要因素,具体影响机制有待进一步研究。
In order to understand the research status of the deformation mechanism of masonry wall,the vertical shape of the external longitudinal wall of masonry structure was investigated on the spot.Six common vertical shapes of masonry wall were summarized,and the corresponding force diagrams were drawn.The research results of the deformation mechanism of masonry wall and it s influencing factors were summarized.The research status and shortcomings of rotation deformation mechanism of masonry wall were summarized,and the practical significance of further study on rotation deformation mechanism of masonry wall was put forward.The research results show that bend deformation,shear deformation and rotation deformation exist simultaneously in most stages of masonry wall s whole loading process.The rotation deformation which is often neglected has a great influence on the lateral stiffness of the wall.The facade shape and other factors affect the deformation mechanism of the wall,and the specific impact mechanism needs further study.
