比拟杆法在边箱形主梁剪力滞效应分析中的应用研究

摘要

利用比拟杆法对边箱形截面的剪力滞效应进行分析.推导承受集中荷载和均布荷载的简支梁考虑剪力滞效应的正应力计算公式.最后以算例进行分析计算,并利用计算结果与有限元软件计算所得结果进行对比.%Analogous bar method is used to analyze the shear lag effeet in side-box girder. Normal stress calculation formula of considering the shear lag effect in beam is deriv which withstand concentrated load and uniformly distributed load. Finally an example is given to analyze and calculate. And it also compares the calculate results of method presented with of finite element software.
