对一个定向刨花板覆面的冷弯型钢墙板所做试验研究的调查结果进行介绍。静态横向荷载试验在13个全尺寸的墙板样本上进行,通过使用土耳其所采用的施工细节来调查冷弯型钢墙的性能。试验结果显示,在冷弯型钢墙板的底部使用一定几何形状的连接件来转移拉力,可很大程度地影响墙板的整体性能。试验发现,在连接件和与其相邻的底部发生了大范围的破坏,从而阻止了主要的承载机制引发的墙体刚度。其他所观察的变形模式还包括用螺钉连接的定向刨花面板覆面与冷弯型钢墙板的边界的框架构件的倾斜,以及覆面与框架构件的分离。冷弯型钢框架内斜压杆的存在会引起墙板荷载能力和初始刚度的少量增长。这也证实了使用已有文献中的设计公式可较为精确地预测所测量的墙板的承载能力。
The investigation results of the experimental study on cold-formed steel wall panels with one oriented particle board are introduced. Static lateral load tests were conducted on thirteen full-size wallboard samples to investigate the performance of cold-formed steel walls using construction details used in Turkey. The test results show that the use of a certain geometry at the bottom of the cold-formed steel wall panel to transfer tension can greatly affect the overall performance of the wallboard. The test found extensive damage to the connector and its adjacent bottom, preventing the stiffness of the wall caused by the main load-bearing mechanism. Other observed modes of deformation also include the tilting of the frame members at the boundaries of the screw-connected oriented strand board cladding with the cold-formed steel wall panels and the separation of the cladding from the frame members. The presence of diagonal bars in cold-formed steel frames causes a small increase in wallboard load capacity and initial stiffness. This also confirms that the design formula in the existing literature can predict the bearing capacity of the measured wallboard more accurately.
