Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as Figure 1-2 As shown, the energy-dissipating strip shear wall is embedded between the frame and the built-in multiple steel plate walls. The wall includes steel pipe concrete frame columns 1, prefabricated concrete slabs 2, high-damping energy-dissipating materials 3, connectors 4, and intermediate steel plates 5 The steel pipe concrete column 1 is an ordinary steel pipe concrete column or a steel pipe recycled concrete column; the wall is welded by the middle steel plate 5 and the frame column 1, and vertical joints are left between the steel plates, and the two sides of the steel plate 5 are outsourced with prefabricated concrete slabs 2; prefabricated The concrete slab 2 and the middle steel plate 5 are connected by connectors 4; the space reserved between the prefabricated concrete slab 2 and the CFST frame 1 is filled with h...

The invention relates to a shear wall formed by embedding energy-dissipation bars between a frame and a wall with inbuilt multiple steel plates and a construction method. The shear wall with the inbuilt multiple steel plates comprises concrete-filled steel tube frame columns, precast concrete planks, high-damping energy-dissipation materials, connecting pieces and the middle steel plates. After the concrete-filled steel tube frame columns and the middle steel plates are manufactured, the precast concrete planks are manufactured at the same time; gaps are reserved between the precast concrete planks and the frame columns and between the precast concrete planks and the middle steel plates, and the gaps are filled with the high-damping materials. Under the action of an earthquake, the formed high-damping energy-dissipation bar frame firstly dissipates energy to protect the concrete planks and guarantees the integrity of the shear wall, so that the time before the concrete planks are damaged is prolonged, and seismic performance is improved. The precast concrete planks can be quickly replaced after the 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 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 built-in steel plate walls and a method thereof, and belongs to the technical application field of practicality, good seismic resistance and energy consumption performance, and being 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. In recent years, my country is in a period of frequent earthquakes. In 2006 alone, there were 17 earthquake disasters. Among them, the Wenchuan earthquake caused economic losses as high as 645.1 billion yuan, and more than 100,000 casualties. 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 difficu...
