摘　　要：为了改善框架结构梁柱节点容易破坏的特点,提出一种较为理想的钢筋泡沫混凝土复合墙板,用于提高建筑结构抗震性能的能力。运用有限元模拟软件ABAQUS对该墙板进行分析,获得墙板在配置最佳斜向配筋率时的力学性能,分析复合墙板在抵抗水平方向的荷载能力和抵抗变形的能力,以及承载能力、延性。通过模拟分析可知,在斜向配筋率最佳情况下,泡沫混凝土复合墙板具有较强的强度,承载力和延性均达到正常使用要求,能够有效的控制裂缝发展。In order to improve the characteristics of beam and column joints of frame structures which are easy to be broken, a kind of ideal reinforced foamed concrete composite wallboard is proposed to improve the seismic performance of building structures. The Finite Element Method simulation software ABAQUS was used to analyze the wallboard, to obtain the mechanical properties of the wallboard when it was equipped with the optimal oblique reinforcement ratio, to analyze the load resistance and deformation resistance of the composite wallboard in the horizontal direction, as well as the bearing capacity, ductility and hysteresis curve, etc. According to the simulation analysis, it can be seen that under the optimal condition of oblique reinforcement ratio, the foamed concrete composite wallboard has strong strength, and the bearing capacity and ductility meet the requirements of normal use, which can effectively control the development of cracks.
