技术领域technical field
本发明涉及抗震结构体系领域，特别涉及一种可恢复功能新型结构体系。The invention relates to the field of anti-seismic structural systems, in particular to a novel structural system with recoverable functions.
背景技术Background technique
随着抗震技术的进步和社会经济发展水平的提升，抗震设计应逐步由抗倒塌设计向可恢复功能设计转变。可恢复功能结构是目前抗震领域的研究热点，也是未来抗震的重要发展方向。传统的抗震结构注重增强结构的延性，良好的延性和足够的承载力虽能避免结构在强震时产生倒塌，但往往会对结构造成较大的损伤，震后较难修复或代价昂贵。With the advancement of anti-seismic technology and the improvement of social and economic development level, anti-seismic design should gradually change from anti-collapse design to design of recoverable function. Recoverable functional structure is a research hotspot in the field of earthquake resistance at present, and it is also an important development direction of earthquake resistance in the future. Traditional seismic structures focus on enhancing the ductility of the structure. Although good ductility and sufficient bearing capacity can prevent the structure from collapsing during strong earthquakes, it often causes greater damage to the structure, making it difficult or expensive to repair after the earthquake.
因此，研制开发一种能够在强震后快速恢复其正常使用功能的可恢复功能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 recoverable functional structural system that can quickly restore its normal function after a strong earthquake.

The upper end of the cable is anchored on the top of the column, and the lower end is anchored on the foundation. The column and the beam are connected by a high-strength prestressed cable, and the two ends of the replaceable energy-dissipating component are respectively installed on the adjacent column. .
所述的柱为钢筋混凝土柱或钢管混凝土柱或钢柱。The column is a reinforced concrete column or a steel tube concrete column or a steel column.
所述的梁为钢筋混凝土梁或钢管混凝土梁或钢梁。The beam is a reinforced concrete beam or a steel pipe concrete beam or a steel beam.
所述的可更换耗能构件为金属耗能部件或黏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 energy-dissipating component 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.

本发明具有如下显著优点：The present invention has following remarkable advantages:
(1)能够有效减轻上部结构的破坏。相比目前已有的上部结构与基础完全固定的传统抗震结构，本发明通过在强震时的受控摇摆反应可以有效减轻上部结构破坏。(1) It can effectively reduce the damage of the superstructure. Compared with the existing traditional anti-seismic structure in which the superstructure and the foundation are completely fixed, the present invention can effectively reduce the damage of the superstructure through the controlled sway response during strong earthquakes.
(2)有利于结构的震后修复或更换。本发明主要将耗能和损伤集中在可更换耗能构件，有利于强震后对可更换耗能构件进行修复或更换。(2) Conducive to post-earthquake repair or replacement of structures. The invention mainly concentrates energy consumption and damage on the replaceable energy consumption component, which is beneficial to repair or replace the replaceable energy consumption component after a strong earthquake.
(3)震后残余变形小。本发明通过设置在结构中的高强预应力拉索可以对结构提供自复位能力，有效减小结构的震后残余变形。(3) The residual deformation after the earthquake is small. The invention can provide self-reset capability for the structure through the high-strength prestressed cable arranged in the structure, and effectively reduce the residual deformation of the structure after the earthquake.
本发明可用于高烈度地震区的重要建筑结构中，不仅能够有效减轻结构主要受力构件的破坏，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.
