Displacement Response Analysis of Internal Factors of Reinforced Concrete Columns under Horizontal Impact Load
Abstract
The reinforced concrete (RC) column is an important force-bearing member in the structure. Therefore, it is necessary to study the displacement response of the RC column under impact load. In order to correctly understand the performance and characteristics of the RC column under the horizontal impact load, and provide reference for the improvement of the RC column impact design. A finite element model of RC column was established by using the finite element software ANSYS/LS-DYNA. Four kinds of internal factors such as column height, longitudinal reinforcement ratio, concrete strength and axial compression ratio were discussed in the horizontal impact load. The effect of the displacement response of the RC column under action. The results show that the displacement response of the RC column under horizontal impact loads can be reduced by increasing the longitudinal reinforcement ratio and increasing the axial compression ratio within a certain range.
