摘要
介绍了薄壁箱梁剪力滞效应及常用求解方法,通过对一具体例题的有限元求解,详细阐述了剪力滞现象的存在。剪力滞后现象使翼缘有效分布宽度的确定成为正截面承载力计算的关键,结合现行规范,对考虑箱梁有效宽度后的应力计算结果与有限元求解结果进行了对比。
The paper introduces the hysteresis effects of shear force and the common solving process. By finite element solving of specific example, the paper elaborates existance of hysteresis effects of shear force. The hysteresis effects may make effective distriblltion width of lip be determined ,which is a key to calculation of bearing capacity of normal section. In the light of specification in force, the stress calculating results of beam box with effective width is compared to ones of finite
