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。
The finite element model of the H-beam simply supported cantilevered beam was constructed by using Madis finite element software to study the effect of weakening of cross-section on the force and deformation of concrete beams. The results show that the stress and displacement of H-CFST crown beam under load are larger than that of solid concrete crown beam. The stress distribution of H-CFST crown beam and solid concrete crown beam is obvious along the beam length direction s difference.
