摘　　要：采用Madis有限元软件建立中穿H型钢简支冠梁的有限元模型,研究截面削弱对混凝土梁受力及变形的影响。研究表明:中穿H型钢混凝土冠梁在荷载作用下,其位移及应力比实体混凝土冠梁的大;沿梁长方向,中穿H型钢混凝土冠梁与实体混凝土冠梁的应力分布形式有明显的不同。By using Madis finite element software to establish the model of the simply supported top beam through H - beams, study on concrete beams and weakening of section deformation. The results show that the displacement and stress of the H steel reinforced concrete crown beam are larger than that of the con-crete crown beam under load; Along the long direction of the beam, the stress distribution of the H steel reinforced concrete crown beam and concrete crown beam is obviously different.
