上海铁路新客站工程设计是采用高架候车的形式,如图1所示。在悬臂的端部。纵向柱距为12.0m,每隔4.0m设次梁,次梁亦为6.0m跨,带有3.0m长的悬臂。施工阶段,悬臂端和预制梁的连结点按铰接考虑;使用阶段,构造上形成刚接,按6.0+19.5+6.0m三跨连梁考虑。主、次梁的布置构成正交梁系,在主、次梁的相交结点处,既有弯曲变形,又有扭转变形,要同时取 Shanghai Railway New Passenger Station project design is the form of elevated waiting bus, as shown in Figure 1. At the end of the cantilever. Longitudinal column spacing of 12.0m, every 4.0m minor beams, secondary beams also 6.0m span, with 3.0m long cantilever. Construction stage, the cantilever end and the prefabricated beam connection point by the hinge to consider; use stage, the formation of the formation of just connected, according to 6.0 +19.5 +6.0 m three cross beams considered. The arrangement of the main beam and the secondary beam forms an orthogonal beam system. At the intersection of the primary beam and the secondary beam, there are both bending deformation and torsional deformation, and at the same time
