不同静力等效方式对结构位移的影响分析

Influence of Static Equivalent Ways on Displacement Calculation of the Structure

探讨了在不同静力等效方式下,结构的力学响应;由结构力学的位移计算方法,从理论上推导位移计算公式,并以一个典型的简支梁模型为例,计算其在4种静力等效工况下的弯矩及位移。研究结果表明,在进行有限元计算时需在荷载作用位置处建立节点。

The paper discussed the mechanical responses under different static equivalent manners, based on the displacement calculation method of structural mechanics, a displacement formula was derived theoretically, and then taking a simply supported beam model as an example, the bending moment and displacement of the four kinds of static equivalent operating conditions were calculated. The results recommended the establishment of nodes should be conducted in the loading position in the finite element calculation.
