摘要
按《玻璃幕墙工程技术规范》(JGJ 102—2003)进行幕墙抗震设计时,风和地震作用的效应组合表达形式与现行其他国家规范以及欧洲标准有所不同。本文对幕墙承载力极限状态设计时的幕墙地震作用效应组合形式提出设计建议。结合试验数据以及超高层建筑幕墙的实际特性,对幕墙位置系数、状态系数和动力放大系数取值进行调整。此外,在调整后的地震作用效应组合形式和动力放大系数新建议取值的基础上,对超高层建筑顶部区域幕墙有无地震作用效应的组合值结果进行比较,提出一些设计建议。
According to the Technical Code for Glass Curtian Wall Engineering （JGJ 102--2003 ） , the combination expression of wind load and earthquake action is different from the actual other national codes and European standard in seismic design of curtain wall. The new combination expression of earthquake action for ultimate bearing capacity design of eurtian wall is suggested. Based on test data and actual characteristics of super high-rise building curtain walls, the position coefficient, state coefficient and dynamic amplification coefficient are adjusted. Meamtime, according to the suggested combination expression of earthquake action and dynamic amplification coefficient, the combination values of loads with and without earthquake action are compared, and some design suggestions are proposed.
