| 摘 要： | 在桥梁结构中组合梁的弹性计算是一项重要的内容,然而要精确计算组合梁在弹性剪切连接(即有滑移)时的应力,须用到微分方程的解析解,在简单荷载作用下的静定结构还可得到这些解析解,但当荷载形式较复杂或为超静定结构时,要得到解析解就很困难了.目前还没有即简便,精度又高的实用计算方法,在<钢结构规范>1](GB50017-200...

| Abstract: | The elastic analysis of composite beams is an important content in bridge engineering.However,an accurate calculation of stresses of composite beams with elastic shear connections(with slips) is quite inconvenient,because a closed solution is needed.Getting a closed solution is possible for simple loads and is very difficult for complicated loads or statically indeterminate beams.At present a simple and accurate calculation method is not available and a related content cannot be found in(national norm) code... |
