Buffering facilities for enhanced seismic performance in mixed-structure buildings with bottom frame

Abstract

The invention provides a buffer facility for improving the seismic performance in a bottom frame hybrid structure building, and belongs to the technical field of civil engineering. The buffer facilityis composed of bumper posts (1), a bottom frame structure (2), masonry structures (3), top cross bridges (4) and a pull rope pulley (18); the buffer facility is characterized in that the bumper posts(1) are located on the both sides of the long edge of the bottom frame hybrid structure building, and the tops of the masonry structures (3) are connected through the top cross bridges (4); each buffer post (1) is composed of fixing support pillars (5), unit partition plates (6), buffer units (7), pull rope rods (8), buffer springs (9) and thread-off prevention steel frames (10); the fixing support pillars (5) are arranged at the lower parts of the bumper posts (1), and the thread-off prevention steel frames (10) are arranged in the fixing support pillars (5); the upper parts of the bumper posts (1) comprise the multiple buffer units (7), and the unit partition plates (6) are arranged between every two adjacent buffer units (7); the buffer units (7) are internally provided with the pull rope rods (8), and the pull rope rods (8) are connected together through the buffer springs (9) in a hooking mode.

Description

technical field [0001] The invention relates to a buffer facility for enhancing the anti-seismic performance in a building with a bottom frame mixed structure, which belongs to the technical field of water conservancy and civil engineering. Background technique [0002] Earthquake disaster is a kind of sudden natural disaster, which is caused by plate tectonic movement, which causes the crust to squeeze and collide with each other. When the long-term accumulated energy of rocks in the crust reaches a certain level, it is released instantly, causing earth The surface fluctuates violently. Severe earthquakes will cause huge casualties and a large amount of property losses in a short period of time. Earthquakes will destroy lifeline facilities such as houses, roads, bridges and dams, and cause secondary disasters such as fires, tsunamis and mudslides. A devastating blow within ten seconds will also have a profound impact on the fear of human psychology. Therefore, earthquake ...

Problems solved by technology

[0003] In order to overcome the problem of unsatisfactory anti-seismic performance of the mixed structure building with bottom frame structure, the present invention provides a buffer facility for enhancing the anti-seismic performance in the mixed structure building with the bottom frame. The buffer columns are symmetrically arranged on both sides of the long side of the hybrid structure building, and the two buffer columns are connected by a top cross bridge at the top of the masonry structure. During an earthquake, the buffer columns provide a lateral traction resistance for the masonry structure, thereby increasing The shock absorption performance of the bottom frame hybrid structure building can reduce the damage degree of the bottom frame hybrid structure building by the earthquake, and finally achieve the purpose of overcoming the unsatisfactory seismic performance of the bottom frame structure hybrid structure building
