【摘要】：混凝土框架梁柱节点作为抗震的关键部位,其抗震性能对结构的破坏程度起着举足轻重的作用。目前国内外对混凝土梁柱节点的研究资料很多,但只是单一的对梁柱节点的抗震性能研究和对其影响因素的研究,缺少墙板对梁柱节点抗震性能的研究。本文在先前单纯研究框架梁柱节点的基础上,考虑了楼板和直交梁的作用,构件研究更符合地震时的真实情况。本文着重研究密肋复合墙板对框架梁柱节点抗震性能的影响,我们把密肋复合墙板和框架结构的组合称之为框架—密肋复合墙板结构。密肋复合墙板是一种新型结构体系,它集围护、承重、抗震耗能于一体,在目前已有的研究和实践中都有良好的性能表现。本文采用以普通混凝土为框格,内嵌加气混凝土砌块的一种密肋复合墙板进行模拟分析。本文研究的主要内容:1、采用大型通用有限元软件ABAQUS建立了3组框架结构梁柱节点和框架—密肋复合墙板梁柱节点。这3组框架结构梁柱节点和框架—密肋复合墙板梁柱节点分别为中层中节点、中层边节点及中层角节点,并对它们进行有限元非线性模拟分析。2、对以上节点进行有限元非线性分析,并对计算结果进行整理,分别对各个梁柱节点裂缝出现的位置及开裂程度、滞回曲线、骨架曲线、耗能能力、延性性能和刚度退化进行分析,并对比分析了密肋复合墙板对框架梁柱节点在以上各个方面的影响。从以上各个方面分析对比可知,密肋复合墙板的使用对于框架结构节点在抗震方面的提升作用很大,进而增强了整个框架结构的安全性能。3、提出从造价和抗震的角度对密肋复合墙板进行优化,然后将框架—密肋复合墙板结构和框架结构及框架—剪力墙结构进行对比,提出密肋复合墙板的布置原则,并分别考虑从尺寸方面、形状方面和拓扑方面对整体的框架—密肋复合墙板结构进行优化,从而在最合理的经济条件下,达到最佳的抗震效果。
[Abstract]:As the key part of the earthquake resistance, the seismic performance of concrete frame beam column joints plays an important role in the damage degree of the structure. At present, there are many researches on concrete beam column joints at home and abroad, but they are only a single research on the seismic behavior of beam column joints and its influencing factors. In this paper, on the basis of the previous study of frame beam column joints, the function of floor and direct beam is considered, and the research of component is more in line with the real situation of earthquake. This paper focuses on the effect of multi ribbed composite wall panels on the seismic behavior of frame beam column joints. We call the combination of multi ribbed composite wall panels and frame structures as frame multi ribbed composite wall panels. Multi ribbed composite wallboard is a new structural system, which integrates enclosure, load-bearing and seismic energy dissipation. It has good performance in current research and practice. This paper uses the ordinary concrete as the sash, embedded in aerated concrete multi ribbed composite wall is simulated and analyzed. The main contents of this paper are as follows: 1. 3 groups of frame structure beam column joints and frame multi ribbed composite wall beam column joints were established by using the large-scale general finite element software ABAQUS. The 3 groups of frame structure beam column joints and frame multi ribbed composite wall beam column joints are middle, middle, and middle angle nodes respectively, and finite element nonlinear simulation analysis is carried out. 2, nonlinear finite element analysis of the above nodes, and the results are sorted, and the degree of cracking, position of each beam column joints cracks hysteresis curves, energy dissipation capacity, ductility and stiffness degradation were analyzed, and the comparative analysis of the influence of multi ribbed composite wall of frame beam column the nodes in the above aspects. From all aspects above, we can see that the use of multi ribbed composite wallboard plays a great role in improving the seismic performance of frame structure joints, and further enhances the safety performance of the whole frame structure. 3, put forward the optimization of multi ribbed composite wall from the cost and the angle of the seismic, and then the frame of multi ribbed composite wall structure and frame structure and frame shear wall structure are compared, put forward the layout principle of multi ribbed composite wall, and considering the size, shape and topology of the whole frame multi ribbed composite wall structure is optimized, resulting in the most reasonable economic conditions, to achieve the best effect of earthquake.
