Description
技术领域technical field
本发明属于涉及土木工程抗震结构体系领域，具体涉及一种装配式自复位摇摆钢板墙结构体系。The invention belongs to the field of anti-seismic structural systems of civil engineering, in particular to an assembled self-resetting swing steel plate wall structural system.
背景技术Background technique
地震是一种破坏性极强的突发性自然灾害，对人类社会构成严重威胁。在土木工程领域，为了应对地震灾害，各种技术层出不穷，如采用阻尼器的耗能减震技术、采用隔震支座的隔震技术、采用吸振器的调谐减震等。近年来，“可恢复功能”结构逐渐成为学术届和工程届关注的热点之一，这其中“自复位结构”和“摇摆结构”已有了一定的研究和实践。Earthquake is a sudden and extremely destructive natural disaster, which poses a serious threat to human society. In the field of civil engineering, in order to cope with earthquake disasters, various technologies emerge in an endless stream, such as energy-dissipating shock absorption technology using dampers, shock isolation technology using shock-isolation bearings, and tuned shock absorption using shock absorbers. In recent years, the "recoverable function" structure has gradually become one of the hot spots in the academic and engineering circles. Among them, "self-resetting structure" and "swing structure" have been researched and practiced to a certain extent.
一般的摇摆结构及自复位结构是指放松结构与基础间约束或构件间约束，使结构与基础或构件间接触面处仅有受压能力而无受拉能力，则结构在地震作用下发生摇摆，通过自重或预应力使结构复位。这为设计具有恢复功能的结构提供了一种新思路，基于这种思路人们先后开发了一些摇摆及自复位的结构体系：可自复位的球入式带翼摇摆隔震墩柱(CN 104278620 A)，自复位梁-格栅式摩擦墙结构体系(CN 203583708 U)、带可更换连梁的自复位剪力墙(CN 203626080 U)、钢筋混凝土摇摆墙、摇摆墙组件及其制作方法(CN101851965 B)、一种套筒式连接的钢筋混凝土摇摆墙组件(CN 104631616 A)、一种可恢复功能的叠合板式剪力墙(CN 203640084 U)等。这些体系多是利用混凝土材料设计的摇摆墙和构件，且多无法实现预制拼装功能。The general rocking structure and self-resetting structure refer to loosening the constraints between the structure and the foundation or the constraints between the components, so that the contact surface between the structure and the foundation or the components has only the compressive capacity but no tensile capacity, and the structure will sway under the action of the earthquake. , to reset the structure by self-weight or prestress. This provides a new way of thinking for designing structures with recovery functions. Based on this way of thinking, people have successively developed some swinging and self-resetting structural systems: self-resetting ball-entry type winged swinging shock-isolation piers (CN 104278620 A ), self-resetting beam-grid friction wall structure system (CN 203583708 U), self-resetting shear wall with replaceable connecting beam (CN 203626080 U), reinforced concrete swinging wall, swinging wall assembly and manufacturing method thereof (CN101851965 B), a sleeve-connected reinforced concrete swing wall assembly (CN 104631616 A), a composite slab shear wall with recoverable function (CN 203640084 U), etc. Most of these systems are rocking walls and components designed using concrete materials, and most of them cannot realize the function of prefabricated assembly.
近年来，在国家的推动下，建筑工业化成为行业发展的重要趋势之一，各类装配式的结构体系日新月异，如一种全预制框架钢支撑结构(CN 203334474 U)、一种装配式组合钢板剪力墙(CN 204983239 U)、装配式双层钢板内填混凝土组合剪力墙结构体系(CN204983269 U)等，但这些都不具备自复位的耗能功能。随着工业化研究的推进，也有人将自复位概念引入预制剪力墙中，如预制装配式自复位剪力墙结构(CN 204876196 U)，该发明主要借助了上、下片墙体之间的变形，利用弹簧和阻尼器形成了耗能和自复位功能，但没有使墙体充分摆动起来，未形成摇摆墙的减震形式。In recent years, under the impetus of the state, the industrialization of construction has become one of the important trends in the development of the industry. Various prefabricated structural systems are changing with each passing day, such as a fully prefabricated frame steel support structure (CN 203334474 U), a prefabricated combined steel plate shear Force wall (CN 204983239 U), prefabricated double-layer steel plate filled concrete composite shear wall structure system (CN204983269 U), etc., but these do not possess the energy consumption function of self-resetting. With the advancement of industrialization research, some people have introduced the self-resetting concept into prefabricated shear walls, such as the prefabricated self-resetting shear wall structure (CN 204876196 U). Deformation, using the spring and damper to form energy dissipation and self-resetting functions, but it does not make the wall fully swing, and does not form the shock absorption form of the swing wall.
钢板剪力墙具有很好的抗侧力能力，关于它的研究工作一直从未停止，且已在实际工程中有较多的应用。由于主要材料为钢材，这类构件具有较高的工业化潜力。因此，本发明旨在设计一种装配式自复位摇摆钢板墙结构体系，将建筑工业化、摇摆结构、自复位和耗能减震的理念融为一体。The steel plate shear wall has a good ability to resist lateral force. The research work on it has never stopped, and it has been widely used in practical engineering. Since the main material is steel, this type of component has high industrialization potential. Therefore, the present invention aims to design an assembled self-resetting swinging steel plate wall structure system, which integrates the concepts of building industrialization, swinging structure, self-resetting and energy consumption and shock absorption.

本发明的原理：Principle of the present invention:
将摇摆钢板墙与框架结构结合，形成框架摇摆钢板墙结构体系，将钢板墙底部从固接变成了铰接，结构体系基本周期延长，钢板墙承载力需求减小。预制带肋钢板嵌在边框钢梁、钢柱内，利用其肋和预制填充板抑制钢板屈曲，形成了具有较大刚度钢板剪力墙体系，从而保证了钢板墙内部变形较小、整体摇摆。当地震来临时，结构发生变形，摇摆钢板墙与主结构之间产生相对位移，耗能元件耗散地震能量，钢板墙底部由于设置为铰接，钢板墙并不发生破坏；地震发生后，由于自复位拉索的存在，结构具有较高的恢复原先位置的能力。与此同时，大部分拼接节点采用螺栓连接，使摇摆结构具有了预制拼装的特性。The swinging steel plate wall is combined with the frame structure to form a frame swinging steel plate wall structure system, and the bottom of the steel plate wall is changed from fixed to hinged, the basic period of the structural system is extended, and the demand for the bearing capacity of the steel plate wall is reduced. The prefabricated ribbed steel plate is embedded in the frame steel beams and steel columns, and the buckling of the steel plate is restrained by the ribs and the prefabricated filling plate, forming a steel plate shear wall system with high rigidity, thus ensuring small internal deformation and overall swing of the steel plate wall. When an earthquake strikes, the structure deforms, and relative displacement occurs between the swaying steel plate wall and the main structure. With the existence of the reset cable, the structure has a high ability to restore the original position. At the same time, most of the spliced joints are connected by bolts, giving the rocking structure the characteristics of prefabricated assembly.
