Mixed control damping structure with overall reset function

Abstract

The invention discloses a mixed control damping structure with an overall reset function. The mixed control damping structure with the overall reset function comprises a damping frame which is formed by an upper portion frame and a lower portion frame, a flat-plate sliding support is arranged between the lower portion of the frame stand column of the cross point of the vertical and the horizontal main frame beams of the upper portion frame and the lower portion frame, a laminate rubber support is arranged between the lower portion of the frame stand column of the cross point of the sub-frame beams of the upper portion frame and the lower portion frame, and a viscous damper is arranged on the outermost main frame beam of the damping frame. The construction damping structure of the mixed control damping structure with the overall reset function comprehensively adopts laminate rubber shock isolation, the flat plate sliding support and the viscous damper to form a mixed control damping system, respective advantages of devices are played, earthquake energy is dissipated, and therefore an ideal damping effect is achieved.

Description

technical field [0001] The invention relates to a building shock absorbing device. Background technique [0002] After the magnitude 8.0 earthquake in Wenchuan on 5.12 and the magnitude 7.1 earthquake in Yushu, Qinghai, people now have higher and higher requirements for anti-seismic technology, and put forward higher requirements for the anti-seismic level of buildings. The traditional anti-seismic structural system resists earthquakes by enhancing the performance of the structure itself, such as adding steel bars and increasing the cross-sectional dimensions of beams, columns, and walls. In this way, with the improvement of the anti-seismic level of building buildings, the steel bars and cross-sectional dimensions of the building structure will become geometric multiples The increase will greatly increase the structural construction cost, and will have a serious impact on the layout of the housing space and the aesthetics of the structure. The traditional anti-seismic meth...

The traditional anti-seismic structural system resists earthquakes by enhancing the performance of the structure itself, such as adding steel bars and increasing the cross-sectional dimensions of beams, columns, and walls. In this way, with the improvement of the anti-seismic level of building buildings, the steel bars and cross-sectional dimensions of the building structure will become geometric multiples The increase of the structure will greatly increase the construction cost of the structure, and will have a serious impact on the layout of the house space and the beauty of the structure.

Traditional structural anti-seismic methods are becoming more and more difficult to meet the increasing anti-seismic requirements

[0003] In the prior art, laminated rubber bearings and flat sliding bearings are generally used as shock absorbing devices alone, which cannot meet high seismic requirements.
