摘　　要：采用有限元分析软件ANSYS对普通钢筋混凝土轴心受压柱和湿式外包钢加固轴心受压柱进行了相关力学研究,对两种柱在加载过程中混凝土裂缝的发展及混凝土、钢筋和外包钢的应力分布进行了对比分析。研究表明,在提高构件的延性和承载力方面,外包钢骨架发挥了较好的作用。Based on ANSYS, the reinforced concrete column and the steel encased concrete column under the axial compression are researched into mechanical behavior. The crack patterns and the stress distribution characteristics of the concrete are researched in the procedure of numerical simulation load test. And the stress distribution characteristics of the steel bars and the steels encased are analyzed also. The analysis found that the steel encased frame plays an important role in reinforcing ductility and bearing capacity.
