beam and girder construction

crossed beams is better than ribbed beam and girder construction floor in large span structure

论大跨距空间结构的交叉梁结构优于肋形楼盖主次梁结构

According to the influence factors of girder displacement and the action effects combination, taking all displacements and rotations of girder end, improving the design methods for displacement parameters of beam-ends devices and construction.

基于梁端位移的影响因素和作用效应组合的研究成果，充分考虑了梁端各方向的变位，改进了梁端附属装置和梁端构造的位移参数的设计方法。

Beam-ends displacement is a important design parameters for construction and devices of girder end, and for the bridge health monitoring.

梁端位移不仅是梁端附属装置和梁端构造的一个重要设计参数，也是缆索承重体系桥梁健康监测的重要参数之一。
