一种多道防线抗震自复位装配式框架-摇摆墙耗能结构A Multi-line Defense Seismic Self-resetting Assembled Frame-Swing Wall Energy Dissipating Structure

技术领域technical field

Many scholars have shown that the deformation between the layers of the frame-swaying wall structure is basically the same, and the structural damage tends to be uniform, which significantly improves the damage caused by the excessive concentration of building damage. It is easier to achieve the design criteria of "strong column weak beam" and "strong shear weak bending", which improves the seismic performance of the structure.

具体实施方式detailed description

下面结合附图对本发明作进一步说明。The present invention will be further described below in conjunction with accompanying drawing.

实施例1Example 1

本发明的框架-摇摆墙耗能结构包括三道抗震防线，下面结合附图进一步说明。The frame-swing wall energy dissipation structure of the present invention includes three anti-seismic defense lines, which will be further described below in conjunction with the accompanying drawings.

如图1所示，一种多道防线抗震自复位装配式框架-摇摆墙耗能结构，包括框架结构1和摇摆墙2，框架结构与摇摆墙墙体铰接，铰接处设置转角位移阻尼器5,摇摆墙墙体底部与地基铰接，摇摆墙墙体两侧设置有预应力筋4，框架结构上设置有若干可控塑性铰节点3；As shown in Figure 1, a multi-line anti-seismic self-resetting assembled frame-swing wall energy dissipation structure includes a frame structure 1 and a swing wall 2, the frame structure and the swing wall are hinged, and a corner displacement damper 5 is set at the hinge , the bottom of the rocking wall is hinged to the foundation, prestressed tendons 4 are arranged on both sides of the rocking wall, and a number of controllable plastic hinge nodes 3 are arranged on the frame structure;

在摇摆墙墙体与框架结构的铰接处设置有转角位移阻尼器，摇摆墙及转角位移阻尼器可为框架结构提供侧向支撑，保证框架结构整体工作整体耗能，同时设置转角位移阻尼器可增强框架-摇摆墙结构的耗能能力。摇摆墙及转角位移阻尼器是第一道抗震防线；A corner displacement damper is provided at the hinge of the swing wall and the frame structure. The swing wall and the corner displacement damper can provide lateral support for the frame structure to ensure the overall energy consumption of the frame structure. At the same time, setting the corner displacement damper can Enhancing the energy dissipation capacity of frame-swing wall structures. Swing walls and angular displacement dampers are the first line of anti-seismic defense;

摇摆墙墙体两侧设置有预应力筋，通过后张法使预应力筋一端固接于地基，另一端与摇摆墙顶部锚接，采用预应力筋将框架-摇摆墙结构中摇摆墙墙体与基础相连，通过预应力筋施加给摇摆墙一个向下的作用力，可以消除框架-摇摆墙结构的高阶模态振型，削弱结构的扭转变形，给结构提供一种在震后自我恢复的能力；添加预应力筋可以有效地减小结构在各种载荷作用下的水平偏移量以及扭转偏移量，是一种安全可靠、经济适用、施工方便、构造简单的减振和提高抗震性能措施；预应力筋采用1×7股的φs15.2高强低松弛钢绞线，在摇摆墙墙体每侧至少设置1束。Prestressed tendons are arranged on both sides of the rocking wall, and one end of the prestressed tendons is fixed to the foundation through the post-tensioning method, and the other end is anchored to the top of the rocking wall. It is connected to the foundation and exerts a downward force on the swinging wall through prestressed tendons, which can eliminate the high-order mode shape of the frame-swinging wall structure, weaken the torsional deformation of the structure, and provide the structure with a self-recovery ability after an earthquake Adding prestressed tendons can effectively reduce the horizontal offset and torsional offset of the structure under various loads. It is a safe, reliable, economical, convenient construction, and simple structure for vibration reduction and improvement of seismic performance. ; The prestressed tendons use 1×7 strands of φ s 15.2 high-strength and low-relaxation steel strands, and at least one bundle is installed on each side of the swing wall.

预应力筋可为框架-摇摆墙结构提供自复位能力和耗能能力，具有震后自恢复的特点，使框架-摇摆墙结构即使大震后也能投入使用，这是第二道抗震防线。The prestressed tendons can provide self-resetting ability and energy dissipation capacity for the frame-swaying wall structure, and have the characteristics of self-recovery after an earthquake, so that the frame-swaying wall structure can be put into use even after a major earthquake. This is the second line of earthquake resistance.

框架结构上设置有若干可控塑性铰节点，如图2、3、4所示，可控塑性铰节点包括柱端短梁段6和主梁预埋件7，柱端短梁段一端与混凝土柱浇筑连接，另一端为球形凹槽8，主梁预埋件一端与主梁浇筑连接，另一端为万向球9，万向球与球形凹槽相配合使主梁预埋件与柱端短梁段铰接连接；A number of controllable plastic hinge nodes are set on the frame structure, as shown in Fig. 2, 3, and 4. The controllable plastic hinge nodes include the short beam section 6 at the column end and the embedded part 7 of the main beam. One end of the short beam section at the column end is connected to the concrete The column is connected by pouring, and the other end is a spherical groove 8. One end of the main beam embedded part is connected with the main beam pouring, and the other end is a universal ball 9. The universal ball is matched with the spherical groove to make the main beam embedded part and the column end Short beam section hinged connection;

如图5所示，为了使整体结构在地震作用后能够快速恢复抗震性能，在可控塑性铰节点上还增加了连接柱端短梁段和主梁预埋件的上下两块组合钢板10，组合钢板上设置有螺栓孔11，柱端短梁段的球形凹槽端和主梁预埋件的万向球端均设置有相对应的螺栓孔，上下两块组合钢板通过高强螺栓与柱端短梁段和主梁预埋件连接在一起。由于上下组合钢板的存在，在地震作用下，结构的变形和耗能集中在组合钢板上，仅组合钢板进入塑性耗能，其余部分和主体结构处于弹性范围，地震作用后，可以通过更换组合钢板实现结构整体功能的快速恢复。可控塑性铰节点，大大提高了框架-摇摆墙结构的整体耗能能力，实现了框架-摇摆墙的理想破坏模式，这是第三道抗震防线。As shown in Figure 5, in order to enable the overall structure to quickly recover the seismic performance after the earthquake, two upper and lower combined steel plates 10 connecting the short beam section at the end of the column and the embedded part of the main beam are added to the controllable plastic hinge node. Bolt holes 11 are set on the composite steel plate, and corresponding bolt holes are provided on the spherical groove end of the short beam section at the column end and the universal ball end of the main beam embedded part. The short beam section and the main beam embedded parts are connected together. Due to the existence of the upper and lower combined steel plates, under the earthquake, the deformation and energy consumption of the structure are concentrated on the combined steel plate, only the combined steel plate enters the plastic energy consumption, and the rest and the main structure are in the elastic range. After the earthquake, the combined steel plate can be replaced Realize the rapid recovery of the overall function of the structure. The controllable plastic hinge joint greatly improves the overall energy dissipation capacity of the frame-sway wall structure, and realizes the ideal failure mode of the frame-sway wall, which is the third line of earthquake resistance.

为了在施工时可把万向球比较容易的放置于球形凹槽内，柱端短梁段的球形凹槽端设计为可拆卸结构；为了使主梁预埋件主梁更好的固定连接，主梁预埋件的一端设计为钢筋笼结构，通过混凝土浇筑与主梁连接在一起；组合钢板的截面可以为U型或L型。In order to place the universal ball in the spherical groove relatively easily during construction, the spherical groove end of the short beam section at the column end is designed as a detachable structure; in order to make the main beam of the main beam embedded part better fixed and connected, One end of the main beam embedded part is designed as a steel cage structure, which is connected with the main beam through concrete pouring; the section of the combined steel plate can be U-shaped or L-shaped.

由于框架-摇摆墙结构在外部荷载作用下，容易出现水平位移峰值过大，残余变形较大的现象，因此框架结构上还设置有调谐质量阻尼器，调谐质量阻尼器包括质量块12、弹簧13、阻尼器14和固定件15，质量块与固定件之间分别设置有弹簧、阻尼器。Since the frame-swaying wall structure is prone to excessive peak value of horizontal displacement and large residual deformation under the action of external load, a tuned mass damper is also installed on the frame structure, and the tuned mass damper includes a mass block 12 and a spring 13 , a damper 14 and a fixed part 15, and a spring and a damper are respectively arranged between the mass block and the fixed part.

调谐质量阻尼器设置在结构顶部，可以将框架-摇摆墙结构上的设施改造为调谐质量阻尼器，利用调谐质量阻尼器将振动频率调整至主结构频率附近，改变结构共振特性，以达到减震效果。安装调谐质量阻尼器也是框架-摇摆墙振动控制的一种有效措施。The tuned mass damper is set on the top of the structure, and the facilities on the frame-swaying wall structure can be transformed into a tuned mass damper. The tuned mass damper is used to adjust the vibration frequency to near the frequency of the main structure and change the resonance characteristics of the structure to achieve shock absorption. Effect. Installing tuned mass dampers is also an effective measure for frame-swing wall vibration control.

本发明的框架-摇摆墙耗能结构可装配，以塑性铰节点为拆分点，拆分成混凝土梁、混凝土柱、梁柱节点、摇摆墙等构件，可实现装配式施工，符合大力发展装配式建筑、推动产业结构调整升级的产业发展需求。The frame-swing wall energy dissipation structure of the present invention can be assembled, and the plastic hinge joint is used as the split point to be split into concrete beams, concrete columns, beam-column joints, swing walls and other components, which can realize assembled construction and conform to the vigorous development of assembly The industrial development needs of modern buildings and promoting the adjustment and upgrading of industrial structure.
