单层厂房为机械工业普遍采用的一种厂房形式,主体结构为砖排架、钢排架或钢筋砼排架,屋面多采用钢筋砼有檩或无檩屋盖,围护墙为砖墙或钢筋砼墙板。1975年海城地震和1976年唐山地震中 ,大量单层厂房遭到严重破坏甚至整幢房屋倒塌,造成重大经济损失和人员伤亡。因此,研究改进单层厂房的抗震分析方法, The single-storey factory building is a type of factory building commonly used in the machinery industry. The main structure is a brick row, a steel rack, or a reinforced concrete truss. The roofs are mostly reinforced or untwisted roofs, and the retaining walls are brick walls or Reinforced concrete wall panels. In the 1975 Haicheng Earthquake and the 1976 Tangshan Earthquake, a large number of single-storey factory buildings were severely damaged or even the entire building collapsed, causing major economic losses and casualties. Therefore, to study the improvement of seismic analysis methods for single-storey buildings,
