高层RC结构小震下变形验算若干问题研究

Several Problems about Antiseismic Deformation Check of HighRise RC Building under Frequent Earthquake

综合考虑了试验结果、计算结果、实际工程计算侧移角的统计结果和多遇地震下建筑结构的容许破坏程度等因素，提出了符合多遇地震设防目标的结构层间弹性位移角限值．探讨了高层建筑结构中。

Considering test results, computing results, statistical results of drift angle in actual engineering computing and permissible degree of structural damage under frequent earthquake, the author presents the allowable interstorey drift index which conforms even more to the fortified objective of frequent earthquake. With regard to the interstoreyed rigid body displacement generated by global bending deflection of highrise building,the author approaches its proportion formed in entire interstoreyed displacement and relevant regular pattern by computing.
