单层钢筋混凝土柱工业厂房在确定烈度作用下,表现出不同的抗力反应。可根据已有震例和数理统计的原理,提出以厂房屋盖形式、厂房的布置、防震缝的设置、连接点、厂房结构的整体性、柱的选择、围护结构作为表征结构抗力的主要指标。定义结构抗力等级划分标准,统计回归出各单层钢筋混凝土柱工业厂房的震害特征因素与抗力指标之间的结构抗震性能评价新模型。研究表明:选取厂房的表征因素作为抗力的主要指标符合评判的标准,回归的抗力指标函数符合抗震能力计算的要求,为群体的单层钢筋混凝土柱厂房的抗震评价提出新思路。
Single-story reinforced concrete column industrial plant in determining the intensity of the show different resistance. According to the principle of the existing earthquake cases and mathematical statistics, it is proposed to use the form of the plant roof, the layout of the plant, the setting of the earthquake-resistant seams, the connection point, the integrity of the plant structure, the selection of columns, and the envelope as the main characterization of the structural resistance index. Define the standard of structural resistance grade division, and deduce a new model of structural seismic performance evaluation between the characteristic factors of earthquake damage and the resistance indexes of single-storey reinforced concrete column industrial buildings. The results show that the selection of the plant characterization factor as the main index of resistance meets the criterion of evaluation, and the regression index function meets the requirements of seismic capacity calculation, which provides a new idea for the seismic evaluation of single - story reinforced concrete columns.
