摘要
目前,钢结构广告牌时常发生安全事故。落地钢结构广告牌主要承受风荷载和自重,通过分析某落地钢结构广告牌的整体稳定性,立柱和水平梁的弯曲正应力、剪应力,来评估该结构的安全性,为类似结构设计提供参考。
The steel billboard accidents frequently occur now.The landing steel billboard primarily bears the wind load and dead-weight.Here, the security of a landing steel billboard is evaluated through analyzing its integrity stability,and the normal stress and shear stress of the upright column and horizontal beam,so as to offer references for dealing with similar structural designs in the future.
