一、引言我院根据国内外大跨度厂房的抗震经验,于1977年在某地(7度区)设计建成了一批抗震试点性工业厂房屋盖,跨度有18～36米,开间有单跨的,也有多跨的,面积约有×万平方米,正在建设的尚有×万平方米。厂房屋盖在抗震设计上的改进主要是将装配——整体式屋盖的作法及“钢板铰”型的梁柱连接节点推广到中小型跨度厂房的屋盖上。下面分别叙述它们的抗震效果及设计、试验、施工的情况。二、装配——整体式屋盖国外工业厂房及大跨度厂房的抗震经验表明,只要将现有的屋盖体系稍加改革,把预制——装配式改变成预制——装配——整体式(简称装配——整体式),加强屋盖的
I. INTRODUCTION According to the seismic experience of large-span plants at home and abroad, our institute designed and built a batch of housing covers for earthquake-resistant pilot industrial plants in a place (7-degree zone) in 1977. The span is 18 to 36 meters. There are single spans in the bay. There are also many spans, with an area of about 10,000 square meters, and there are still 10,000 square meters under construction. The improvement of the factory housing cover in the seismic design is mainly to promote the assembly—the method of the integral roof and the “steel plate hinged” beam-column connection node to the roof of the small and medium-sized span factory building. The following describes their seismic performance and design, testing and construction. Second, the assembly - the overall roof of the foreign industrial plant and large-span factory building seismic experience shows that as long as the existing roof system has been slightly reformed, the prefabrication - prefabricated to prefabricated - assembly - integral type ( Abbreviated assembly - monolithic, reinforced roof
