预应力钢带约束混凝土柱有限元分析

摘要

This essay uses ANSYS to simulate prestressing concrete square columns confined with prestressed steel strip, and details the modeling methods for ANSYS simulation, including the selection of element type and its constitutive relations, the mesh and pre-stressing etc., and the simulation results are compared with experimental results. The simulation results are in good agreement with the experimental results, indicating that during a simulation the selected of material model, element and analysis model is reasonable, it can effectively analyze the axial compression performance of concrete columns confined with prestressed steel strip.%本文运用ANSYS对已试验的预应力钢带约束混凝土方柱进行了数值模拟，详细介绍了ANSYS模拟的建模方法，包括单元类型和本构关系的选取，网格划分以及预应力的施加等，并将模拟结果与试验结果进行对比，模拟结果与试验结果吻合较好，表明模拟过程中选取的材料模型、单元和分析模型是合理的，能够有效地分析预应力钢带约束混凝土方柱的轴心受压性能。
