在1976年7月唐山地震过程中,大型屋面板与屋架、屋面梁焊接的单层工业厂房遭到了大量破坏,其原因很大部分是由于屋面的塌落引起的。为了保证大型屋面板与屋面梁形成可靠的整体性,提高梁和板的承载能力和变形性能,我们对屋面板与屋面梁做成装配整体式结构进行了较为系统的模拟单元试验研究。本文主要论述装配整体式梁板屋面结构的整体性能和水平刚度问题,供工业厂 During the Tangshan earthquake in July 1976, a large number of single-story industrial plants welded to large roof panels, roof trusses, and roof beams suffered extensive damage. This was due in large part to the collapse of the roof. In order to ensure the reliable integrity of large roof panels and roof beams and to improve the bearing capacity and deformation performance of beams and slabs, we systematically conducted a simulated unit test study on the integral structure of roof panels and roof beams. This article focuses on the overall performance and horizontal stiffness of an assembled monolithic slab roof structure for industrial plants.
