Transformer substation structural rigidity strengthening device

Abstract

The invention discloses a transformer substation structural rigidity strengthening device. The transformer substation structural rigidity strengthening device is mainly composed of a vertical energy consumption supporting system and a floorslab supporting system. The vertical energy consumption supporting system is mainly composed of buckling-restrained braces, partial buckling-restrained braces and a metal rubber damping device. The floorslab supporting system is mainly composed of welded I-steel. According to the strengthened supporting system, the overall rigidity of the structure is enhanced through different braces, and the structure is less damaged or broken under the earthquake action, the lateral force resisting rigidity of all layers of structure bodies can be improved through the vertical energy consumption supporting system, the plane rigidity of the structure is enhanced through the floorslab supporting system, and the structure bodies are connected into a whole to bear force together. The supporting scheme is an effective solution for planar and vertical irregular structures, and has the characteristics that the using function influence is small, construction is convenient, and the ratio of loss to profit is small, and has wide application prospects for irregular transformer substation structures.

Description

technical field [0001] The invention relates to the field of disaster prevention and reduction in civil engineering, in particular to a structural rigidity enhancing device for a substation. Background technique [0002] With the development of social economy and other aspects, people no longer pursue simple food and clothing, but put forward higher requirements for the quality of life, such as high-quality educational environment, medical and health conditions, and so on. Among them, the power system has almost become the core or an integral part of all walks of life. Today, the requirements for the power system are getting higher and higher, and the position of the substation structure in the power system is also becoming more and more important. [0003] At present, the mainstream of substation structure is reinforced concrete structure. Structural engineers often choose to increase the cross-sectional size of beams and columns in the structural seismic design to improve...

AI Technical Summary

Problems solved by technology

Under the action of an earthquake, the structure may cause vertical vibration of the floor or even vertical collapse; 2) The structure is irregular, and the substation structure is usually irregular in plane and vertical direction, and it is easy to form a weak layer under the action of the earthquake; 3) The equipment is tall and the substation Due to the use of the structure, the height of the equipment floor is very large, sometimes even up to 10m. Considering the structural rigidity, a frame beam will be installed in the middle of the storey. plastic hinge
