Abaqus的Standard模块中,重力通过指定材料的密度、定义静力加载步并施加重力加速度的方式来施加。

In Abaqus/Standard, gravity load are specified by three steps: define the density property of material, define static loading step and apply gravitational acceleration load to the whole model.

SAP2000模型,1点的竖向位移为 -0.05997 mm,接近Abaqus的分析结。

( In SAP2000, the analyzed vertical displacement of node 1 is -0.05997 mm , which is closed to the analysis result provided by Abaqus.)
