Dynamic Response Analysis of the T-Shaped Steel Reinforced Concrete Column under Different Impact Conditions

摘要

This paper simulated the resistance to lateral impact properties of the T-shaped steel reinforced concrete column through the large finite element software ABAQUS. Extracting the time-displacement curves of different impact sites, by comparison we know: with the impact site is farther and farther from solid end, the maximum lateral displacement in the impact site of the member is bigger and bigger. The maximum displacements in the symmetrical place to the mid-span of the member are very similar. From time-displacement curves of seven models we can know, after reaching the ultimate bearing capacity, the curves leveled off gradually and changed slowly showing good stability and showing good ductility and deformation capacity. It can be concluded: the impact different parts of the dynamic response of lateral impact of the T-shaped steel reinforced concrete columns have a certain impact.
