摘　　要：以简支工字形钢梁为例,主要介绍在ABAQUS有限元模拟软件分析下工字形钢梁的一般受力特性,一个是,在外荷载作用下应力–应变之间的关系以及随时间变化的关系。另一个是,在外荷载作用下挠度、位移随时间变化的关系,来综合测定钢梁在均布荷载作用下,钢梁的受力变化及变形发展情况。Taking the simply supported I-shaped steel beam as an example, the general stress characteristics of the I-shaped steel beam under ABAQUS finite element simulation software are introduced. One is the relationship between stress-strain and the change with time under external load relationship. The other is the relationship between deflection and displacement with time under external load to comprehensively determine the force change and deformation development of the steel beam under uniform load.
