Self-resetting steel frame-CLB filler wall and preparation method thereof

Abstract

The invention discloses a self-resetting steel frame-CLB filler wall and a preparation method thereof. The self-resetting steel frame-CLB filler wall comprises a basic steel beam, a plurality of layers of steel frames arranged on the basic steel beam, staggered laminating bamboo wallboards arranged in the layers of steel frames and unbonded prestressed ribs arranged on the staggered laminating bamboo wallboards, one ends of the unbonded prestressed ribs are fixedly connected with the steel frames, and the other ends of the unbonded prestressed ribs are fixedly connected with the basic steel beam. The preparation method of the self-resetting steel frame-CLB filler wall comprises the steps that firstly the staggered laminating bamboo wallboards are prepared according to the arranging position of the unbonded prestressed ribs of the staggered laminating bamboo wallboards; then the steel frames are arranged on the basic steel beam, and the staggered laminating bamboo wallboards are embedded into the steel frames; and finally, the unbonded prestressed ribs are separately and fixedly connected to the steel frames and the basic steel beam, and the self-resetting steel frame-CLB filler wall is prepared. According to the self-resetting steel frame-CLB filler wall and the preparation method thereof, the staggered laminating bamboo wallboards are combined with the steel frames, so that inter-story displacement of various layers of the steel frames tends to be uniform, horizontal displacement of the steel frames is reduced, and anti-seismic multi-channel defensive lines can be constituted.

Description

technical field [0001] The invention belongs to the field of self-resetting structures, in particular to a self-resetting steel frame-CLB filling wall and a preparation method thereof. Background technique [0002] For traditional steel frame structures, it is far from enough to resist earthquake action or wind load only through the frame itself. In order to reduce the horizontal displacement of the steel frame and enhance the structural rigidity, the steel frame and the wall can be combined to form a frame-filled wall structure. The hysteretic curve of the frame-filled wall structure is full, the energy dissipation capacity is strong, and the seismic performance is improved. However, most of the current frame-filled wall structures are steel frame-concrete filled walls, and most of the connection forms are steel connectors with bolts. The concrete infill wall is self-heavy and connected to the existing frame, which is easy to increase the seismic action of the structure, ...

AI Technical Summary

Problems solved by technology

At present, most of the existing self-resetting structures are reinforced concrete structures, which are self-heavy and difficult to hoist after prefabrication; and steel and concrete are non-renewable resources, which do not meet the requirements of sustainable development
