摘　　要：被广泛使用的压型钢板具有受力蒙皮效应,但由于在我国没有专门的规范可循,所以只被用作结构的刚度储备,造成了经济上的浪费。为了研究其刚度贡献,分别在有蒙皮和无蒙皮两种情况下对框架抗侧移刚度进行了现场试验。基于叠加原理,利用曲线拟合方法对试验数据进行了量化,间接得到跨越多檩条的受力蒙皮的抗剪刚度。结果表明,两榀刚架间蒙皮对框架整体刚度的贡献甚至接近于一榀刚架。Although profiled steel sheets have the diaphragm effect in steel structure, since there is no specific code to follow in China, it is only used as the reservation of the structural stiffness. So it results in economic wastes. In order to investigate the contribution of stressed skin to the overall stiffness, field tests are carried out to measure the lateral stiffness of the frames with and without stressed skin diaphgram. Based on the superposition principle and using the curve fitting method, the test results are quantified. The shear rigidity of stressed skin diaphgram spanning several purlins is gained indirectly. It shows that the shear rigidity of the diaphragm between two frames is even close to the lateral stiffness of one frame.
