【摘要】 钢管混凝土在高层建筑中应用较多，钢板剪力墙在超高层建筑中应用近年发展较快。将钢管混凝土的抗震优势与钢板剪力墙的抗震优势合理结合，对提高高层建筑抗震性能十分重要。本文提出并研发了钢管混凝土边框内藏钢板组合剪力墙，并进行了试验研究、理论分析、数值模拟和设计方法研究。主要贡献如下：1．提出并研发了型钢混凝土边框内藏钢板组合剪力墙。进行了5个型钢混凝土边框内藏钢板组合剪力墙模型和1个普通钢筋混凝土剪力墙模型的低周反复荷载试验研究，分析了各试件的承载力、刚度及其退化过程、延性、滞回特性、耗能能力及破坏特征等；与普通钢筋混凝土剪力墙相比较，揭示了型钢混凝土边框钢板混凝土组合剪力墙的抗震机理。2．提出并研发了钢管混凝土边框内藏钢板组合剪力墙。进行了9个钢管混凝土边框内藏钢板组合剪力墙模型的低周反复荷载试验研究，分析了各试件的承载力、刚度及其退化过程、延性、滞回特性、耗能能力及破坏特征等，与型钢混凝土边框内藏钢板组合剪力墙相比较，揭示了钢管混凝土边框内藏钢板组合剪力墙的抗震机理。3．提出并研发了剪力墙内藏钢板与外包钢筋混凝土之间的新型抗剪连接技术。并通过对采用此抗剪连接技术的剪力墙模型进行低周反复荷载试验，验证了此种抗剪连接技术在保证钢板与混凝土间整体性方面的良好性能。4.建立了钢管混凝土边框内藏钢板组合剪力墙和型钢混凝土边框内藏钢板组合剪力墙的承载力计算模型、恢复力模型，并采用软件ABAQUS对有代表性的试件进行了有限元分析，计算结果与实测结果符合较好。根据理论分析，揭示了此种新型组合剪力墙的破坏机制。5．提出了钢管混凝土边框内藏钢板组合剪力墙抗震设计方法和构造措施。包括适用范围、一般规定、在结构中的布置原则和构造措施。根据试验研究结果，得出如下主要结论：1.与普通钢筋混凝土剪力墙相比，钢管混凝土边框内藏钢板剪力墙和型钢混凝土边框内藏钢板剪力墙的抗震性能更好。不仅承载力高、刚度大，而且由于钢管混凝土边框柱对剪力墙的约束更强，使钢管混凝土边框内藏钢板剪力墙承载力和刚度的退化速度减慢，表现出更好的延性和耗能能力。2.钢管混凝土边框内藏钢板组合剪力墙，由于剪力墙墙体内藏钢板的设置，有效延迟了剪力墙斜裂缝的出现并制约了其继续发展，提高了剪力墙的后期刚度,改善了其破坏机制。3.在钢板开孔率适当和配筋率相同的情况下，新型钢板混凝土连接件的性能与栓钉性能相当，但其变形能力较好，有利于剪力墙的耗能。更多还原

【Abstract】 Concrete filled steel tube (CFST) has been used more often in high-rise buildings,at the same time the steel plate shear wall is also being applied with rapiddevelopment in recent years. The rational combination of CFST and steel plate shearwall is important for improving the anti-seismic performance of high-rise buildings.The embedded steel plate composite shear wall with CFST columns has beendeveloped in the thesis. And experimental study, theoretical analysis, numericalsimulation and design method about it were conducted. The main contributions are asfollows:1．An embedded steel plate shear wall with profile steel reinforced concretecolumns has been proposed. The low cyclic loading tests of5composite wallspecimens and1normal RC shear wall specimen have been carried out. The columnstyle, thickness of plate, connections and axial force ratio were considered. The loadbearing capacity, stiffness degradation, ductility, hysteretic behavior, energydissipation capacity and failure characteristics have been analyzed. The effect ofprofile steel reinforced concrete boundary columns and the embedded steel plate onimproving the entire seismic behavior of the shear wall has been revealed.2．A new embedded steel plate composite shear wall with CFST columns hasbeen proposed. The low cyclic loading tests of9specimens have been carried out.The column style, thickness of plate, shear span ratio, connections and axial forceratio were considered. The load bearing capacity, stiffness degradation, ductility,hysteretic behavior, energy dissipation capacity and failure characteristics have beenanalyzed. Compare with the embedded steel plate shear wall with profile steelreinforced concrete columns, the embedded steel plate composite shear wall withCFST columns shows better seismic behavior.3．A new shear connecting technique between the internal steel plate and theexternal concrete has been proposed and studied. It is demonstrated that the integratedseismic performance between steel plate and concrete is good by low cyclic loadingtests of specimens with the technique.4．The load bearing capacity calculated model and the restoring force model ofthe embedded steel plate composite shear wall with CFST columns and the embeddedsteel plate shear wall with profiled steel reinforced concrete columns have beenestablished. Simulation of several typical specimens has been conducted by the finite element analysis software ABAQUS. The computed results agree well with the testresults. According to the theoretical calculation and analysis, the failure mechanism ofthe new composite shear wall is made.5．Suggestions about design and construction measures of the new wall,including the general rules, scope of application and the principles of construction aregiven.According to results of the research, main contributions are as follows：1． Comparing with the normal RC shear wall，the embedded steel plate shearwall with profiled steel reinforced concrete columns and the embedded steel platecomposite shear wall with CFST columns shows excellent seismic behavior withhigher load bearing capacity, larger initial stiffness. Constrained by the strongerboundary CFST columns, the embedded steel plate composite shear wall with CFSTcolumns has better ductility and better energy dissipation capacity.2． Owing to the steel plate embedded in the wall, the occurrence of inclinedcracks on surface of concrete wall is delayed, and their development is alsoconstrained. Thus the late rigidity of the shear wall is well held. At the same time, thefailure mechanism of the wall is also improved.3． In the case of rational plate opening rate and the same reinforcement rate,the wall equipped with new connectors between the embedded steel plate and outerconcrete has nearly the same working performance, the better capacity of deformationand energy dissipation than using steel studs.更多还原
