Description
技术领域technical field
本实用新型属于土木工程抗震与减震领域，涉及一种可更换的竖波软钢阻尼器。The utility model belongs to the field of anti-seismic and shock-absorbing civil engineering, and relates to a replaceable vertical wave mild steel damper.
背景技术Background technique
传统建筑主要靠结构自身变形来吸收地震能量，许多主要构件损伤后很难被修复。随着抗震理论、技术、方法的不断进步以及更多高性能材料的发展应用，人们对结构的抗震性能要求越来越高，结构抗震已由抗倒塌设计逐步向可恢复功能设计转变，以期在震后将整个社会的损失降到最低。Traditional buildings mainly rely on the deformation of the structure itself to absorb earthquake energy, and many major components are difficult to repair after damage. With the continuous advancement of anti-seismic theory, technology and methods and the development and application of more high-performance materials, people have higher and higher requirements for the anti-seismic performance of structures. After the earthquake, the loss of the whole society will be minimized.
在实现可恢复功能结构的这几种方法中，目前最具有可操作性的是可更换结构，在结构中设置可更换的结构构件，在强震时使结构的损伤主要集中在可更换构件，不仅可以利用其有效耗散地震输入结构能量，而且有利于震后对受损的可更换构件快速更换，尽快恢复结构的正常使用功能。Among the several methods to realize the recoverable functional structure, the most operable is the replaceable structure. Replaceable structural components are set in the structure, and the damage of the structure is mainly concentrated in the replaceable components during strong earthquakes. Not only can it be used to effectively dissipate the earthquake input structural energy, but also it is beneficial to quickly replace the damaged replaceable components after the earthquake, and restore the normal function of the structure as soon as possible.
金属阻尼器尤其是软钢阻尼器是一种良好的减震隔震构件，由于金属在进入塑性状态后具有良好的滞回特性，并在弹塑性变形过程中吸收大量能量，因而被用来制造不同类型和构造的耗能减震器。从受力形式上可分为轴向屈服型、剪切屈服型、弯曲屈服型和扭转屈服型阻尼器，已有的耗能阻尼器有以下这几种：X形和三角形耗能器、扭转梁耗能器、弯曲梁耗能器、U型钢板耗能器、钢棒耗能器、圆环耗能器、双圆环耗能器、加劲圆环耗能器等。相比于其粘弹型、摩擦型、粘滞液体型等其他类型阻尼器，金属阻尼器易加工、滞回性能稳定、易于更换、造价及维护费用低廉，因此被广泛应用于工程结构的抗震加固和修复领域。Metal dampers, especially mild steel dampers, are good shock-absorbing and shock-isolating components. Because metals have good hysteresis characteristics after entering the plastic state, and absorb a lot of energy during elastic-plastic deformation, they are used to manufacture Energy-dissipating shock absorbers of different types and constructions. From the force form, it can be divided into axial yield type, shear yield type, bending yield type and torsional yield type damper. The existing energy dissipation dampers are as follows: X-shaped and triangular energy dissipation, torsional Beam energy dissipation device, bending beam energy dissipation device, U-shaped steel plate energy dissipation device, steel bar energy dissipation device, circular energy dissipation device, double circular ring energy dissipation device, stiffened circular ring energy dissipation device, etc. Compared with other types of dampers such as viscoelastic, friction, and viscous liquid, metal dampers are easy to process, have stable hysteresis performance, are easy to replace, and have low cost and maintenance costs, so they are widely used in earthquake resistance of engineering structures. Reinforcement and repair areas.
传统的金属阻尼器大多为放置于梁内的剪切型阻尼器，对于放于剪力墙体内的既受拉压又受剪切的软钢阻尼器目前研究甚少，在现有技术中，研究的基本都是纯拉压或纯剪切型阻尼器，因此需要设计出一种阻尼器，该阻尼器能够在水平方向及竖直方向均具有优良的减震耗能性能。Most of the traditional metal dampers are shear type dampers placed in the beam. There is little research on the mild steel damper placed in the shear wall that is subjected to both tension, compression and shear. In the existing technology , the studies are basically pure tension-compression or pure shear dampers, so it is necessary to design a damper that can have excellent shock absorption and energy dissipation performance in both horizontal and vertical directions.

实施例一Embodiment one
参考图6，将本实用新型应用于型钢混凝土剪力墙中，具体的，在剪力墙上预留阻尼器安置腔，然后将阻尼器安装于阻尼器安置腔内，通过上端板1及下端板2分别与剪力墙内的型钢及下层楼面构件相连接，其中，阻尼器安置腔的位置根据地震作用的能量大小及地震作用下剪力墙墙趾易发生破坏的塑性区域确定。Referring to Fig. 6, the utility model is applied to the steel concrete shear wall. Specifically, a damper installation chamber is reserved on the shear wall, and then the damper is installed in the damper installation chamber, and the upper end plate 1 and the lower end Plate 2 is respectively connected to the section steel in the shear wall and the lower floor members. The location of the damper installation cavity is determined according to the energy of the earthquake and the plastic area where the toe of the shear wall is prone to damage under the earthquake.
阻尼器中各部件均采用焊接，耗能部件在地震发生后，首先产生塑性变形进行耗能，保证结构自身不受破坏，震后即可拆卸后进行更换。All components in the damper are welded. After the earthquake occurs, the energy-consuming components first produce plastic deformation to dissipate energy to ensure that the structure itself is not damaged. After the earthquake, it can be disassembled and replaced.
另外，剪力墙因被挖去一定的空间，承载能力下降，通过减小阻尼器平行高度范围内的剪力墙水平分布钢筋的间距来补偿损失的承载力，然后装入阻尼器的剪力墙的承载力与原有剪力墙的承载力基本持平。In addition, the bearing capacity of the shear wall is reduced due to the excavation of a certain space. The lost bearing capacity is compensated by reducing the spacing of the horizontally distributed steel bars in the shear wall within the parallel height range of the damper, and then the shear force of the damper is installed. The bearing capacity of the wall is basically the same as that of the original shear wall.
