【摘要】 针对目前实际工程中对钢货架结构纵向抗侧体系及抗震性能研究的不足,对高层货架结构与多层货架结构进行抗震性能对比分析,通过不同的模型来研究背拉体系与水平支撑对这两种钢货架结构的影响。研究结果表明,钢货架结构可以简化为单榀模型来进行抗震分析。无纵向抗侧体系的钢货架结构受力方式与钢框架结构类似,高层货架结构受力方式与多层钢货架结构存在较大差异性,仅设背拉但无水平支撑的多层钢货架的抗侧能力几乎没有提高,背拉支撑与水平支撑相结合方可形成有效的结构纵向抗侧体系。更多还原

【Abstract】 In this paper, in view of the inadequacy of the lateral anti-leaning system and the shake-proof performance of the steel racking systems in practice, we compared the shake-proof performance of the high rack structure with the multi-storey rack structure and studied the influence of the back-tension system and lateral bracing on the two structures and at the end, elaborated on the conclusions reached.更多还原
