【摘要】 异形柱结构由于其结构的特殊性,可将柱子隐于墙体,使房内不出棱角,以增加房屋有效使用面积,从而受到开发商的亲睐。将原先矩形柱结构改为异形柱结构后,通过高烈度下弹塑性动力时程分析,考查了某异形柱框架结构在设防和罕遇地震水准下的整体抗震性能,对结构能否达到抗震设防目标进行了初步评价。结果表明,该异形柱结构在设防烈度和罕遇烈度地震作用下基本能够达到预期的抗震设防目标。更多还原

【Abstract】 Special-shaped column structures are favored by developers for cryptostructure of the pillars,no edges in the room,and they can increase effective use area of the building. After changing the original rectangular column structure to the special-shaped column structure,the paper analyses overall seismic performance of special-shaped column frame structure under the fortification and the rarely met earthquake intensities through dynamic elastoplastic time history analysis,and makes the preliminary evaluation. The results show that,the special-shaped column structure achieves basically the goal of desired seismic fortification.更多还原
