简支箱梁结构变形计算
The shear lag has been studied for many years. Nevertheless, most of the studies are related to the effect of the shear lag on stressdistribution and very few have investigated the effect on deflection, although some design codes have formulas for the effect of the shearlag on deflection. In this conjunction, the present study carries out three-dimensional finite element analyses for various box girders to investigate the deflection at the mid-span. The multimesh extrapolation is employed to ensure the accuracy. The present study thus reveals the influence of the parameters that characterize the geometry of a box girder on the deflection. It is also shown that the formulas adopted in the design codes underestimate the deflection considerably. Based on the present numerical results, empirical formulas are proposed to compute the deflection magnification factors that account for the difference between the deflections due to the finite element 本站免费提供《简支箱梁结构变形计算》下载，我们己经对《简支箱梁结构变形计算》进行全面的整理检查，以保证您安全的下载《简支箱梁结构变形计算》，如果下载的压缩文件需要密码那就是本站的网址 http://www.xiaozhibei.com，简支箱梁结构变形计算的文件大小为451 KB，本站还有大量关于结构论文,结构论文方面的资源提供下载哦，可以多找找。为下次能方便快速的找到本站，记得收藏我们的网址（http://www.xiaozhibei.com）哦！
