Shear wall formed by embedding energy-dissipation bars between frame and wall with inbuilt multiple H-shaped steel plates and construction method

Abstract

The invention relates to a shear wall formed by embedding energy-dissipation bars between a frame and a wall with inbuilt multiple H-shaped steel plates and a construction method. The shear wall with the inbuilt multiple H-shaped steel plates comprises concrete-filled steel tube frame columns, precast concrete planks, high-damping energy-dissipation materials, connecting pieces and the middle H-shaped steel plates. The concrete-filled steel tube frame columns and the middle H-shaped steel plates are manufactured; strip-shaped spaces are reserved between the precast concrete planks and the frame base and beam part and between the middle H-shaped steel plates, and the strip-shaped spaces are filled with the high-damping materials to form the high-damping energy-dissipation frame. By the application of the multiple H-shaped steel plates, energy dissipation in blocks and strips is achieved, and the energy-dissipation capacity of the large-span wall is strengthened. The precast concrete planks can be quickly replaced after an earthquake, so that the post-seismic restoring speed is increased, and the use function of houses can be restored as soon as possible. As the multiple H-shaped steel plates are applied in a large-span space, the energy dissipation in blocks is achieved, and the materials can be fully utilized. Accordingly, good social benefits are achieved, and application prospects are broad.

Description

technical field [0001] The invention relates to an energy-dissipating strip shear wall embedded between a frame and a plurality of H-shaped steel plate walls and a method thereof, which belongs to the application technical field of a novel and practical, good seismic-resistance and energy-dissipating performance, and is suitable for high-rise structures. Background technique [0002] Earthquake is one of the natural disasters that seriously endanger human beings. It has the characteristics of suddenness, regionality and destructiveness. At present, due to the increasing shortage of urban land and the diversification of social needs, the height and span of buildings are increasing, and their shapes are becoming more and more complex. The difficulty of seismic analysis and design of structures is increasing. Many high-rise buildings that have been built or are under construction in our country are located in strong earthquake areas, facing the threat of serious earthquake disa...
