Description
技术领域technical field
本发明涉及一种由波形钢板与钢管混凝土构件组成的剪力墙，属于结构工程技术领域。The invention relates to a shear wall composed of corrugated steel plates and steel tube concrete components, which belongs to the technical field of structural engineering.
背景技术Background technique
剪力墙结构具有抗侧刚度大、承载力高、抗震性能好等优势，在高层民用建筑中有广泛应用。钢筋混凝土剪力墙是最早应用的剪力墙单元，其使用热度至今仍然不减，但由于混凝土材料具有脆性破坏的特征，在地震作用下延性不佳。钢板剪力墙相较钢筋混凝土剪力墙，在承载力和延性方面均有所提高，并具有良好的滞回性能和耗能能力。但为了充分发挥钢板剪力墙力学性能和经济性能方面的优势，钢板厚度不宜过大，且需采取一些措施，防止钢板墙过早出现屈曲而不屈服，如设置加劲肋、混凝土盖板或采用波形钢板等。之后迅速发展起来的钢板与混凝土所组成的各种形式的剪力墙，因其能通过组合效应，充分发挥钢和混凝土两种材料各自的优势，在高层建筑市场中应用比较活跃。其中，以平钢板-混凝土组合墙、钢管束-混凝土组合墙和波形钢板-混凝土组合墙在工程建设中应用最多。平钢板包裹混凝土所组成的剪力墙，在浇筑混凝土时需要支撑模板，施工措施费较高，为保证平钢板的受力性能，往往还需要较为密集地布置剪力连接件，会影响内部混凝土的填充，并且墙体破坏时仍不能避免其发生脆性断裂，延性不佳。钢管束-混凝土组合墙由多个C形截面冷弯型钢依次焊接所组成，自然焊接工作量较大，生产效率低下，特别当上、下两块组合墙连接时，在其对接位置内部的竖向板件难以焊接，故不能连续贯通，导致内部的竖向板件不能直接传递轴向力。波形钢板-混凝土组合墙则需要独立地制作波形钢板，还需要特制对穿螺栓，如果手工组装，工厂效率不高，如果采用自动化和智能化生产线，还需要进一步研制相应的设备。The shear wall structure has the advantages of large lateral stiffness, high bearing capacity, and good seismic performance, and is widely used in high-rise civil buildings. Reinforced concrete shear wall is the earliest applied shear wall unit, and its use is still unabated. However, due to the brittle failure characteristics of concrete materials, the ductility under earthquake is not good. Compared with reinforced concrete shear walls, steel plate shear walls have improved bearing capacity and ductility, and have good hysteretic performance and energy dissipation capacity. However, in order to give full play to the advantages of the steel plate shear wall in terms of mechanical properties and economic performance, the thickness of the steel plate should not be too large, and some measures should be taken to prevent the steel plate wall from buckling prematurely without yielding, such as setting stiffeners, concrete cover slabs or using Corrugated steel plate, etc. Various forms of shear walls composed of steel plates and concrete developed rapidly afterwards, because they can give full play to the respective advantages of steel and concrete through the combination effect, and are relatively active in the high-rise building market. Among them, the flat steel plate-concrete composite wall, the steel pipe beam-concrete composite wall and the corrugated steel plate-concrete composite wall are the most used in engineering construction. The shear wall composed of flat steel plate wrapped with concrete needs to support the formwork when pouring concrete, and the construction cost is high. In order to ensure the mechanical performance of the flat steel plate, it is often necessary to arrange shear connectors densely, which will affect the internal concrete. Filling, and brittle fracture cannot be avoided when the wall is damaged, and the ductility is not good. The steel pipe bundle-concrete composite wall is composed of a plurality of C-shaped cross-section cold-formed steels welded in sequence. Naturally, the welding workload is large and the production efficiency is low. Especially when the upper and lower composite walls are connected, vertical It is difficult to weld the vertical plate, so it cannot be continuously penetrated, so that the internal vertical plate cannot directly transmit the axial force. The corrugated steel plate-concrete composite wall needs to be made independently of the corrugated steel plate, and special through-bolts are also required. If it is assembled manually, the factory efficiency is not high. If an automated and intelligent production line is used, the corresponding equipment needs to be further developed.
鉴于上述问题，有必要设计一种新型组合剪力墙，在保证承载力和延性的同时，提高生产效率，降低施工难度和建设成本。In view of the above problems, it is necessary to design a new type of composite shear wall, which can improve production efficiency and reduce construction difficulty and construction cost while ensuring bearing capacity and ductility.
