【摘要】 综合国内外规范关于结构抗扭设计的规定,就扭转不规则的界定和分类等问题进行了论述。对国内外规范中判断扭转不规则的参数进行了研究,对具体取值进行了评估。对扭转不规则系数的主要影响因素进行了分析,为地震作用下结构的抗扭设计提供了理论依据。更多还原

【Abstract】 Comparisons were made about the provisions of different seismic codes about torsion effect and torsional resistance design. Then torsional irregular measure was discussed . The parameters of torsional irregularity in seismic codes were studied and the limit values were evaluated. The effect factors on the parameter of torsional irregularity were analyzed. The conclusion provides theory basis to torsional resistance design of structures under earthquake.更多还原
