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.

一个桁架的重力分析（A gravity load analysis of a truss）。

（1）定义材料的密度 (define the density property of material)

（2）定义静力荷载步 并 施加重力加速度 (define static loading step and apply gravitational acceleration load)

（3）结果（Analysis Results）

1点的竖向位移为 -0.0599903 mm. ( The vertical displacement of node 1 is -0.0599903 mm.)

（4）SAP2000分析结果（SAP2000 Analysis Results）

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.)
