［摘要］結(jié)合工程實(shí)例，對平面尺度指標(biāo)超限結(jié)構(gòu)體系的抗震性能進(jìn)行分析。在建筑功能對結(jié)構(gòu)豎向構(gòu)件布置存在限制的前提下，提出改善結(jié)構(gòu)抗側(cè)剛度和抗扭能力的措施，并對最大彈性層間位移角接近混凝土高規(guī)限值規(guī)定進(jìn)行可行性研究。對轉(zhuǎn)換層位于層2，且層高較高的特殊情況，應(yīng)同時(shí)驗(yàn)算3項(xiàng)剛度比指標(biāo)方能達(dá)到控制轉(zhuǎn)換層剛度突變的目的。采用屈服判別法研究結(jié)構(gòu)在中震作用下的抗震性能，可在宏觀上把握結(jié)構(gòu)薄弱部位，有針對性地采取加強(qiáng)措施，以確保結(jié)構(gòu)具備良好的抗震性能。

Abstract:The aseismatic performance of structural system with extending plane dimension index is analyzed for the given project. The proposals are offered for improving the lateral stiffness and tensional ability of the structure, on condition that the architectural functional requirement restricts the position of vertical supports(columns and walls), and the feasibility is analyzed when the maximum elastic storey drift angle is close to the prescriptive value of -Technical Specification for Concrete Structure of Tall Buiding. In the special circumstances of transfer storey in the second floor and storey height beyond the normal level, the aim that controls vertical rigidity sudden changes can be achieved by means of checking three indexes about storey-lateral-stiffness ratio. The weak members can be distinguished on the whole through the studying of the aseismic performance under middle earthquake by the yield prediction method, the intensifying measures are adopted purposefully to ensure the excellent aseismic performance.
Keywords:shear walls supported by frame; plane irregularity; weak member; yield prediction method
