摘要
箱形截面梁剪力滞效应的影响是结构设计中不能忽视的因素.剪力滞效应的存在,使箱梁截面实际应力与按初等梁理论计算出的应力有很大差异.若忽略此影响会造成结构设计的不安全.对简支箱梁剪力滞效应进行研究,并分析了剪力滞效应的主要影响因素.
The impact of box-girder shear lag can not be ignored in the structural design. The existence of shear lag makes actual stress of box-girder shear lag diverge from stress obtained by elementary beam theory greatly. If this effect is ignored, it will cause insecurity of structure design. This paper discusses on shear lag effect existing in the simple girder, and analyzes the major factors to shear lag's effect.
