摘　　要：通过可视化非线性有限元分析系统对带矩形孔的梁在集中荷载下的全过程仿真分析,详细研究开孔梁的应力、变形、裂缝以及破坏特征等等,总结出其裂缝和破坏的一些特点,为建立开孔梁的设计、验算方法提供更多依据。<Abstrcat> The paper made visual simulative analysis on the reinforced concrete beams with openings by nonlinear finite element method. Detailed study has been made on the beams' mechanical behavior, deformation, cracking and collapse forms under concertrated load. The characteristics of the cracks and the collapse modes were summarized to provide more referenes for the design and the calculation of this kind of the beams.
