技术领域technical field
本发明涉及抗震结构体系领域，特别涉及一种带可更换连梁的自复位剪力墙。The invention relates to the field of anti-seismic structural systems, in particular to a self-resetting shear wall with replaceable connecting beams.
背景技术Background technique
自复位剪力墙是一种新型的结构形式，其可以在中震或大震时通过墙体底部的抬升减轻墙体的破坏，而可更换连梁是在连梁上设置可更换耗能部件，在地震时通过可更换耗能部件的耗能减轻连梁其余部分和墙体的破坏，而且震后方便对可更换耗能部件进行修复更换。但目前大多数研究针对单片自复位剪力墙和带可更换连梁的传统剪力墙，单片自复位剪力墙虽然可以减轻墙体的震害，但却不能减轻与之相连的传统连梁的破坏，带可更换连梁的传统剪力墙虽然可以减轻连梁非屈服段的破坏，但对墙体的保护效果有限。The self-resetting shear wall is a new type of structure, which can reduce the damage of the wall through the uplift of the bottom of the wall during a moderate earthquake or a large earthquake, and the replaceable connecting beam is a replaceable energy-consuming part installed on the connecting beam , during an earthquake, the energy consumption of the replaceable energy-dissipating parts can be used to reduce the damage of the rest of the coupling beam and the wall, and it is convenient to repair and replace the replaceable energy-dissipating parts after the earthquake. However, most of the current research focuses on the single-piece self-resetting shear wall and the traditional shear wall with replaceable coupling beams. Although the single-piece self-resetting shear wall can reduce the seismic damage of the wall, it cannot reduce the traditional shear wall connected to it. For the failure of coupling beams, although the traditional shear wall with replaceable coupling beams can reduce the damage of the non-yielding section of coupling beams, the protection effect on the wall is limited.
因此，研制开发一种既能够提高剪力墙的抗震能力，又能够减轻连梁破坏的新型抗震结构体系就显得既迫切而且特别有意义。Therefore, it is urgent and particularly meaningful to develop a new type of seismic structural system that can not only improve the seismic capacity of shear walls but also reduce the damage of coupling beams.
发明内容Contents of the invention
为了克服目前已有剪力墙结构存在的难以同时减轻墙体和连梁震害的不足之处，本发明提供一种既能够提高剪力墙的抗震能力，又能够减轻连梁破坏的带可更换连梁的自复位剪力墙。In order to overcome the insufficiency of the current existing shear wall structure that it is difficult to reduce the seismic damage of the wall and the coupling beam at the same time, the present invention provides a belt-stable structure that can not only improve the seismic capacity of the shear wall, but also reduce the damage of the coupling beam. Replace the self-resetting shear wall of the coupling beam.
本发明所采用的技术方案是一种带可更换连梁的自复位剪力墙，它由可更换连梁和与之相连的自复位剪力墙构成，所述的可更换连梁由可更换段和非屈服段构成，所述的自复位剪力墙为后张拉无粘结预制剪力墙。The technical solution adopted in the present invention is a self-resetting shear wall with a replaceable connecting beam, which is composed of a replaceable connecting beam and a self-resetting shear wall connected to it, and the replaceable connecting beam is composed of a replaceable segment and non-yielding segment, and the self-resetting shear wall is post-tensioned unbonded prefabricated shear wall.
所述的可更换段为金属耗能部件或粘弹性阻尼耗能部件或摩擦阻尼耗能部件或复合阻尼耗能部件。The replaceable section is a metal energy-dissipating component or a viscoelastic damping energy-dissipating component or a frictional damping energy-dissipating component or a composite damping energy-dissipating component.
所述的非屈服段为钢构件或钢-混凝土组合构件或钢筋混凝土构件。The non-yielding section is a steel member or a steel-concrete composite member or a reinforced concrete member.
所述的后张拉无粘结预制剪力墙的预应力通过高强度抗拉材料施加。The prestress of the post-tensioned unbonded prefabricated shear wall is applied by high-strength tensile materials.
所述的后张拉无粘结预制剪力墙和基础之间设置阻尼器。A damper is arranged between the post-tensioned unbonded prefabricated shear wall and the foundation.
所述的高强度抗拉材料为钢绞线或高强芳纶纤维筋。The high-strength tensile material is steel strand or high-strength aramid fiber reinforcement.
所述的带可更换连梁的自复位剪力墙可以在工厂预制完成，运到现场后安装。The self-resetting shear wall with replaceable connecting beams can be prefabricated in a factory and installed after being transported to the site.
本发明具有如下显著优点：The present invention has following remarkable advantage:
（1）能够有效减轻墙体的破坏。相比目前已有的上部结构与基础完全固定的剪力墙结构，本发明通过墙体在中震或大震时的摇摆可以有效减轻墙体的破坏。(1) It can effectively reduce the damage of the wall. Compared with the existing shear wall structure in which the upper structure and the foundation are completely fixed, the present invention can effectively reduce the damage of the wall through the sway of the wall during a moderate earthquake or a large earthquake.
（2）能够有效减轻连梁的破坏。目前大多数传统连梁在大震时的震害都非常严重，本发明通过可更换连梁不仅能够增强连梁的耗能能力，而且在震后对受损的连梁便于修复更换。(2) It can effectively reduce the damage of the coupling beam. At present, most of the traditional coupling beams suffer very serious earthquake damage during major earthquakes. The invention can not only enhance the energy dissipation capacity of the coupling beams through the replaceable coupling beams, but also facilitate the repair and replacement of the damaged coupling beams after the earthquake.
（3）震后残余变形小。本发明通过设置在墙体中的高强度抗拉材料可以对墙体提供自复位能力，有效减小剪力墙的震后残余变形。(3) The residual deformation after the earthquake is small. The invention can provide self-resetting ability for the wall body through the high-strength tensile material arranged in the wall body, and effectively reduce the residual deformation of the shear wall after the earthquake.
本发明可用于高烈度地震区的重要建筑结构中，不仅能够有效减轻墙体和连梁的破坏，而且具有较好的自复位能力，震后残余变形小，施工方便，造价合理，具有良好的应用前景。The invention can be used in important building structures in high-intensity earthquake areas. It can not only effectively reduce the damage of walls and connecting beams, but also has good self-resetting ability, small residual deformation after earthquakes, convenient construction, reasonable cost and good performance.
