本文扼要地介绍了海城、唐山地震单层工业厂房的主要震害现象,并考虑了厂房的屋面变形,用直接积分方法计算了六座经历过上述地震的单层厂房的弹塑性地震反应。得到的结果与宏观现象基本相符。根据宏观现象和计算结果,文章最后指出:对钢筋混凝土排架单层厂房,目前主要应解决它的屋面系统的抗震设计问题,在高烈度地区使用砖柱厂房必须采取特殊措施。
This article briefly introduces the major earthquake damage phenomena of single-story industrial buildings in the Haicheng and Tangshan earthquakes. Taking into account the roof deformation of the factory buildings, the elasto-plastic seismic response of six single-storey buildings that have experienced these earthquakes is calculated using the direct integration method. The results obtained are basically consistent with the macroscopic phenomena. According to the macroscopic phenomena and calculation results, the article concludes that: Currently, for a single-story factory building with reinforced concrete trusses, the seismic design of its roofing system should be mainly solved. Special measures must be taken to use the brick-column workshop in high-intensity areas.
