【摘要】 通过对大量建筑结构模型模拟地震振动台试验研究成果的整理和分析,在总结建筑幕墙振动台试验经验的基础上,提出改进的建筑幕墙抗震性能评价指标,即加速度放大系数指标和层间位移角指标。分析各指标沿建筑高度的分布规律,探讨建筑幕墙抗震性能评价方法,并对评价指标在工程设计和试验研究中的应用进行阐述。对建筑幕墙的抗震设计方法和抗震性能试验研究方法进行深入探讨,并指出各方法的适用范围和优缺点。最后,用改进的试验方法对建筑幕墙进行振动台试验,利用新的指标来评价幕墙的抗震性能,验证其有效性。更多还原

【Abstract】 Based on the shaking table test results of structural models of high-rise building and architectural curtain wall specimens,the indices for evaluation of the seismic performance of architectural curtain walls,i.e.indices of acceleration magnification coefficients and inter-story drift angles,are put forward.The characteristics of distribution of the indices along the height of the building are analyzed,and the method for appraisal of the seismic performance of architectural walls investigated.Application of the method in curtain wall design and the experimental study are discussed and the advantages and disadvantages pointed out.Shaking table tests of curtain walls are conducted using improved experiment method,and the seismic performance of the specimens are estimated with the indices.更多还原
