Residual Bearing Capacity Numerical Simulation and Theoretical Analysis of H-Shaped Steel Column Impacted under Different Axis Pressure

Abstract

H-beam is usually used as column structure of single industrial workshop, steel column will inevitably encounter lateral impact of lifting weights or factory vehicle in the process of daily production, causing its defects in material and geometry, thus the change of axial bearing capacity.This aratical takes H-shaped steel column of a factory as the research object, establishes its residual bearing capacity theory of finite element analysis model in different situations under the impact using ABAQUS software platform, discusses the load parameters analysis in axial force-impac and Launches the functional relation between axial compression ratio and impact energy, providing a basis for assessing the residual loading capacity of such members after the impact.
