摘　　要：本文应用Abaqus有限元分析软件建立带有X型斜撑的泡沫混凝土复合板与钢筋混凝土框架协同工作状态下的复合墙板模型,通过模拟分析有无异形柱和现浇异形柱(T形柱)不同纵筋直径下泡沫混凝土复合墙板受力性能可知,与异形柱结合的装配整体式异形柱结构墙板承载力和抗震性能明显优于独立工作的墙板,随着异形柱纵筋直径的增大,泡沫混凝土复合墙板的承载力得到显著提升,延性先增大后减小,提升了该结构的承载能力和抗震性能。In this paper,the finite element analysis software Abaqus is used to establish a composite wall panel model of foam concrete composite slab with X-shaped slant support and reinforced concrete frame under the cooperative working state.Through the simulation analysis of the mechanical performance of foam concrete composite wall panels with and without special-shaped columns and cast-in-place special-shaped columns(T-shaped columns)under different longitudinal bar diameters,it can be seen that the stiffness of the wall panel of the assembled monolithic special-shaped column structure combined with special-shaped columns has been significantly improved.With the increase of the diameter of the longitudinal bar of the special-shaped column,the bearing capacity of the foam concrete composite wall panel has been significantly improved,and the ductility first increases and then decreases.
