| 摘 要： | 为分析可变作用对桥梁受力的影响,结合邢台市柏乡牡丹桥的设计工作,研究了斜腿刚架桥箱梁特征断面在各种作用下的弯矩、剪力和轴力,分析了各种作用效应所占的比例.结果表明:该桥边跨跨中以受弯拉为主,中跨跨中以弯压为主,斜腿与箱梁相交处以剪弯为主.最后根据箱梁特征断面的受力性能确定了其各截面的控制作用工况.

| Abstract: | Combining with the design works of Peony Bridge in Baixiang County of Xingtai City to analyze the effect of variable loads to bridges,the bending moment,shear-force,axial-force of the box-beam characteristic section of slant legged rigid frame bridge under every actions were studied,the effect proportions of each action were analyzed.The results show that the side-mid-span section is mainly in bending-tensile state,the middle-mid-span section is mainly in bending-compressive state,and the joint section of slant-leg and box-beam is mainly in shear-bending state.At last,the controlling action are determined according to the loading properties of the box-beam characteristic section. |
