Description

Technical Field

[0001] The invention relates to the technical field of earthquake resistance in civil engineering, and more particularly to an integral sway controllable frame-shear wall structure. Background Art

[0002] The main purpose of traditional earthquake-resistant structures is to control the strength and ductility of the structure. The bearing capacity is designed in case of small earthquakes, and the ductility and deformation of the structure are verified in case of large earthquakes to ensure that the structure does not collapse or break down. However, when a strong earthquake occurs, although the traditional structure can also be designed in accordance with existing specifications, the structure will be seriously damaged, and it is difficult or expensive to repair the structure after the earthquake. For important engineering structures, it is not only required to effectively protect people's lives and property after a strong earthquake, but also emphasized that it should be able to quickly restore the normal use function of the structure after a strong earthquake to avoid causing greater indirect losses. The 2010 Christchurch earthquake in New Zealand showed that the indirect losses and direct losses caused by strong earthquakes to building structures are at the same level.

[0003] The rocking self-righting structure is an effective structural form to reduce structural earthquake damage, but the existing rocking structures have not been able to achieve overall structural deformation control and lack their seismic design methods. Therefore, it is an urgent problem for technicians in this field to develop a tough structure that can effectively reduce structural earthquake losses and propose its seismic design method.
