建筑结构中短柱的界定及对改善抗震性能措施的评述

Circumscription of short pillar and the review of measures no how to inprove the seismic behavior

建筑结构设计特别是高层建筑结构设计中,在结构底部或者设备转换层常常形成短柱,本文依据现行规范及国内外关于柱抗震性能的研究成果,以及作者的结构设计经验,提出如何界定短柱及几种如何改善提高短柱抗震性能的措施,从而使广大结构设计人员更好的把握短柱设计,使短柱避免发生脆性破坏,保证结构安全。

The building structure design especially high-rise building the structure design,in the structure bottom perhaps equipments conversion layer usually formation short pillar,this text according to the current code and domestic and international concerning the pillar anti-vibration ability of research result,and the author＇s structure design experience,put forward how define how short pillar and several kind is improvement exaltation short pillar anti-vibration ability of measure,make thus large structure design the personnel is better confidence short pillar design,making the short pillar avoid occurrence brittleness break,assurance structure safety.
