单层钢筋混凝土柱工业厂房结构抗力研究
|
摘要
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 industrial building of reinforced concrete columns under the determined earthquake intensity will show different reaction of resistant capacity.On the basis of Earthquake cases and the principle of mathematical statistics,it is proposed the main indexes of the resistance that are characterized by roof types,layout,shock seam settings,connection point,structural integrity,column selection and circumambient frame of industrial buildings.The structural resistance grading standards is defined.A new model having the seismic performance evaluation that between earthquake damage characteristic factors and the resistance index has been regressed.Studies have shown that selecting industrial building characterized by factors as key indicators of resistance can meet the evaluation criteria,the return of resistance to anti-seismic capacity index function calculation is in line with requirements,which prolides new ideas for aseismic evaluation of groups of single-story industrial buildings.
