技术领域technical field
本实用新型涉及一种支撑插入式支撑双侧板节点,主要应用于建筑结构中的多层及高层建筑的钢管混凝土组合柱。The utility model relates to a support insertion type support double-side slab node, which is mainly applied to the steel pipe concrete composite columns of multi-storey and high-rise buildings in the building structure.
背景技术Background technique
随着经济全球化,城市化水平的提高,城市人口密集度逐渐增大,使得大量高层不断涌现。这就迫切需要新的技术支持高层及多层建筑的设计与建设。With the economic globalization and the improvement of urbanization level, the urban population density is gradually increasing, which makes a large number of high-rise buildings emerge continuously. There is an urgent need for new technologies to support the design and construction of high-rise and multi-storey buildings.
钢管混凝土利用钢管和混凝土两种材料在受力过程中的相互作用,即钢管对混凝土的约束作用使混凝土处于复杂应力状态,从而使混凝土的强度得以提高,塑性和韧性大为提高。同时,在钢管内部填充混凝土后,由于混凝土的支撑作用,可以避免或延缓钢管壁的屈曲。两种材料的结合弥补了各自的缺点,使得材料性能充分发挥。Concrete filled steel tube utilizes the interaction between the steel tube and concrete in the process of stress, that is, the restraint of the steel tube on the concrete makes the concrete in a complex stress state, so that the strength of the concrete is improved, and the plasticity and toughness are greatly improved. At the same time, after the steel pipe is filled with concrete, the buckling of the steel pipe wall can be avoided or delayed due to the supporting effect of the concrete. The combination of the two materials makes up for their respective shortcomings, making the material performance fully exerted.
随着社会的发展和生活水平的提高,人们对住宅的使用面积和美观性要求越来越高。传统的圆形或方形截面钢管混凝土柱,通常不能完全被墙体包围,柱脚很大一部分突出房间内部,占用一定的室内空间,使得家具摆设和房间布置受到一定限制。采用矩形截面钢管混凝土组合柱,可做到与墙同宽,解决了柱突出棱角的问题。With the development of society and the improvement of living standards, people have higher and higher requirements for the usable area and aesthetics of houses. The traditional round or square cross-section concrete-filled steel tube columns are usually not completely surrounded by walls, and a large part of the column feet protrudes from the interior of the room, occupying a certain amount of indoor space, which limits the furniture and room layout to a certain extent. The steel pipe concrete composite column with rectangular cross-section can be as wide as the wall, which solves the problem of protruding edges and corners of the column.
研究表明,一般形式的矩形钢管混凝土组合柱,钢管对核心混凝土的约束仅限于角点,在周边较弱,承载力相对较低。端柱为矩形钢管的多腔钢管混凝土组合柱在边缘设置约束构件以提高其承载力和耗能能力,横向设置加劲拉结措施,将柱身分隔为若干腔室,使钢板对混凝土的约束作用加强,同时减小钢板的宽厚比,防止或延缓钢板的局部屈曲。Studies have shown that for the general form of rectangular concrete-filled steel tube composite columns, the constraints of steel tubes on the core concrete are limited to the corner points, weaker at the periphery, and the bearing capacity is relatively low. The multi-cavity concrete-filled steel tube composite column whose end column is a rectangular steel tube is equipped with restraint members at the edge to improve its bearing capacity and energy dissipation capacity. Stiffening and tie measures are arranged laterally to divide the column body into several chambers, so that the restraint effect of the steel plate on the concrete Reinforce, reduce the aspect ratio of the steel plate at the same time, prevent or delay the local buckling of the steel plate.

Because the two side panels 2 are provided with the support upper cover plate 4 and the support lower cover plate 6 in advance, then the support square tube 5 is inserted, and it is convenient to insert the slanted beam (support square tube 5) on the spot, without damage Multi-cavity steel pipe concrete composite column saves material and labor.
下面以多腔钢管混凝土组合柱—钢梁U形刚接节点为列说明本实用新型支撑插入式支撑双侧板节点的力学性能。The mechanical properties of the utility model support plug-in support double-side plate joint will be described below by taking the multi-cavity steel pipe concrete composite column-steel beam U-shaped rigid joint joint as a column.
利用ABAQUS软件对节点进行有限元分析,节点柱为200x600的多腔钢管混凝土组合柱,梁采用H350x150x6x10的焊接工字钢,节点处双侧板以及盖板厚度均与梁翼缘同厚。有限元分析结果图7(a)-(c)所示。Using ABAQUS software to conduct finite element analysis on the joints, the joint column is a 200x600 multi-cavity concrete-filled steel pipe composite column, the beam is made of H350x150x6x10 welded I-beam, and the thickness of both side plates and cover plates at the joint is the same as that of the beam flange. The results of finite element analysis are shown in Fig. 7(a)-(c).
由于采用多腔钢管混凝土组合柱,钢管对混凝土有较强的约束作用,柱身整体的承载力以及延性均比较好,实现了强柱弱梁的设计要求。多腔钢管混凝土组合柱—钢梁U形刚节点的破坏顺序如图7(a)-(c)所所示。当作用外力较大时,远离节点连接区的梁端A首先出现塑性铰图7(a)所示,内力重分布,结构的承载力提高;随着外力的增加,梁盖板B先于侧板出现塑性铰图7(b)所示;结构的最终破坏如图7(c)所示,梁端翼缘屈曲,侧板上下侧C大面积屈服,但侧板未形成塑性铰,结构仍具有一定的耗能能力,满足强节点弱构件的设计要求。Due to the use of multi-cavity steel pipe concrete composite columns, the steel pipes have a strong restraint effect on the concrete, and the overall bearing capacity and ductility of the column body are relatively good, which meets the design requirements of strong columns and weak beams. The failure sequence of multi-cavity CFST composite column-steel beam U-shaped rigid joints is shown in Fig. 7(a)-(c). When the external force is large, plastic hinges first appear at the beam end A away from the joint connection area, as shown in Fig. 7(a), the internal force is redistributed, and the bearing capacity of the structure increases; Figure 7(b) shows plastic hinges in the plate; the final failure of the structure is shown in Figure 7(c), the beam end flange buckles, and the upper and lower sides C of the side plate yield in a large area, but the side plate does not form a plastic hinge, and the structure still has certain The energy dissipation capacity meets the design requirements of strong nodes and weak members.
本实用新型根据抗震概念设计原则,结构应具备多道抗震设防线,避免因部分构件破坏而导致整体体系破坏,同时也要求结构应具备必要的强度、良好的变形能力和耗能能力。本实用新型支撑插入式支撑双侧板节点采用多腔钢管混凝土组合柱—钢梁U形刚接节点形式,采用柱与梁端隔离的方式,通过全高度侧板以及盖板构成的节点连接件来传递梁端弯矩以及剪力。当地震作用时,梁端首先出现塑性铰,消耗一定的地震能量形成第一道地震设防线,之后盖板出现塑性铰,进一步耗散地震能量,形成第二道地震设防线,侧板最终形成塑性铰,形成第三道地震设防线。整体结构满足“强柱弱梁,强节点弱构件”的设计原则,结构的耗能性能比较好。如图8所示,节点的滞回曲线饱满,没有明显的捏缩现象,节点的耗能能力好,变形大,当地震来临时,让住户有更多的逃生时间。The utility model is based on the principle of seismic concept design. The structure should have multiple seismic fortification lines to avoid the damage of the whole system due to the damage of some components. At the same time, it also requires that the structure should have the necessary strength, good deformation capacity and energy dissipation capacity. The utility model's supporting plug-in supporting double-side plate joint adopts the multi-cavity steel pipe concrete composite column-steel beam U-shaped rigid connection joint form, adopts the isolation method of the column and the beam end, and uses the node connector composed of the full-height side plate and the cover plate To transmit the beam end bending moment and shear force. When an earthquake occurs, plastic hinges first appear at the end of the beam, which consumes a certain amount of seismic energy to form the first seismic fortification line, and then plastic hinges appear on the cover plate to further dissipate the seismic energy to form the second seismic fortification line, and the side panels finally form Plastic hinges form the third seismic fortification line. The overall structure meets the design principle of "strong columns and weak beams, strong nodes and weak components", and the energy dissipation performance of the structure is relatively good. As shown in Figure 8, the hysteresis curve of the node is full, without obvious pinch phenomenon, the energy dissipation capacity of the node is good, and the deformation is large. When the earthquake comes, the residents have more time to escape.
