摘要
简支梁在纵横向荷载作用下的弯曲变形是土木工程结构物中非常普遍的现象。从推导和建立简支梁纵横弯曲微分方程出发,研究简支梁在纵横向荷载作用下的挠度、弯矩及应力,对简支梁在纵横向荷载作用下弯曲变形的变化进行分析,并通过实例计算出纵横向荷载作用下简支梁的挠度、弯矩及应力的变化情况,得出结论。
The bending deformation of simply supported beam under vertical and horizontal loads is a very common phenomenon in civil engineering structures. Starting from the derivation and the establishment of the differential equations of the simply supported beam,the deflection,bending moment and stress of simply supported beam under vertical and horizontal loads is studied. The change of bending deformation of the simply supported beam is analyzed. Through an example,the change of deflection,bending moment and stress of simply supported beam under vertical and horizontal loads are calculated.
