摘要
为了探究轻型门式刚架结构抗震性能的影响。本文利用有限元分析软件ANSYS对《门式刚架轻型房屋钢结构标准图集》(02SG518-1)[1]中单层单跨门式刚架进行了横向地震作用计算。分析了该结构在不同地震波和不同抗震设防烈度阶段的受力性能、变形特征和破坏机理。最终分析结果表明:标准图集(02SG518-1)刚架的设计符合《建筑抗震设计规范》(GB50011-2010)[2]"小震不坏,中震可修,大震不倒"的抗震设防要求。说明单层单跨门式刚架结构具有优良的抗震性能。
In order to explore light portal frame structure of the effects on seismic characteristics.This paper use of finite element software ANSYS analysis'Atlas of Gate-type Rigid-framed Light House Steel-frame Standard'(02SG518-1)[1] in single-story and single-span portal frame on the horizontal seismic action calculation.This paper analyzes the structure under different seismic wave and different seismic fortification intensity phase of the mechanical properties,deformation characteristics and failure mechanism.Final analysis results show that the standard atla(02SG518-1) frame design accord with'Construction Anti-seimsic Design Standard'(GB50011-2010)[2]'small earthquake not bad,the shock of repairable,not strong'of the requirements for seismicresistance.That single-story and single-span portal frame structure has good seismic performance.
