对单调循环荷载作用下硅酸钙板包覆冷成型钢板剪力墙(CFSSWP)的性能和强度进行研究,并给出试验结果。在此之前,试样经过特殊设计,通过板件和CFS框架的螺栓连接达到其强度,避免出现其他失效模式。试验研究的主要目的:1)研究板的厚度以及螺栓到板边缘的距离对墙体性能和强度的影响;2)研究实际工程中常用的各种钢板剪力墙的性能;3)研究平面内剪切条件下决定钢板剪力墙荷载-变形特性的重要参数值;4)确定CFSSWP中连接板件和CFS框架的失效螺栓的不同极限状态。此外,基于由剪切强度试验得到的螺栓连接件强度,给出确定(2FSSWP极限剪切强度的简单设计方程。
The performance and strength of CFSSWP coated with calcium silicate board under monotonic cyclic loading were studied and the test results were given. Prior to this, the specimens were specially designed to achieve their strength by bolting plate and CFS frames to avoid other failure modes. The main purpose of experimental research: 1) study the thickness of the plate and the distance between the bolt and the edge of the plate on the performance and strength of the wall; 2) study the performance of various commonly used steel plate shear wall; 3) 4) Determine the different limit states of the failed bolts connecting the plate to the CFS frame in CFSSWP. In addition, a simple design equation for determining (2FSSWP ultimate shear strength) is given based on the strength of the bolted joint obtained from the shear strength test.
