在设计T形钢混组合梁时,翼板的纵剪强度有时(例如短柁梁) 会成为控制条件。图1是组合梁隔离体示意,假设受弯中和轴恰好处在Ⅰ形钢梁与混凝土翼板交界面上,在1-1最大弯矩截面上,混凝土翼板面的内压力P_1、P_2、P_3与钢梁中拉力F_(at)相 When designing a T-shaped steel composite beam, the shear strength of the wing (for example, a short truss beam) sometimes becomes a control condition. Figure 1 is a schematic diagram of a composite beam insulator. Assuming that the bending center and axis are just at the interface between the I-shaped steel beam and the concrete wing plate, the internal pressure of the concrete wing plate surface is P_1, P_2 at the 1-1 maximum moment cross-section. , P_3 and F_(at) phase in steel beam
