摘要
根据工业建筑的特点,对金属和轻质混凝土的装配式围护结构抗震计算进行对比分析。结合GB 50011—2010《建筑抗震设计规范》,以及现行有关幕墙和围护系统的标准,对围护结构抗震设计的位置系数、状态系数和动力放大系数取值进行深入探讨,对工业建筑围护结构的地震作用组合形式及效应与风荷载的组合效应进行了比较分析。建议对动力放大系数按照建筑抗震设防类别调整为5.0(乙类)和3.6(丙类),在金属围护墙和轻质混凝土墙板的承载力设计时,一般可仅考虑按非抗震设计组合。
Based on the characteristics of industrial buildings,the seismic design of prefabricated structure composed of metal enclosure wall or light-weight concrete was studied in this paper.According to the Code for Seismic Design of Buildings（GB 50011—2010） and relevant standards for curtain wall and enclosure system,the position coefficient,state coefficient and dynamic amplification coefficient used in seismic design of the wall were deeply discussed.The combined expression and effect of seismic action and wind load for enclosure structure were compared and analyzed in this paper.It was suggested that seismic combination could be usually ignored in designing the bearing capacity of metal enclosure wall and light-weight concrete wall,and the dynamic amplification coefficient should be taken as 5.0and 3.6 for building＇s seismic importance type B or C separately.
