Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] A new post-earthquake self-resetting concrete frame-eccentric support structure system, the structure system includes a self-resetting concrete frame and an eccentric support structure.

[0031] Such as Figure 1-6 As shown, the self-resetting concrete frame of this structural system includes a cup-shaped foundation 4 and a frame column 5; The groove step assembled on the surface, the middle of the groove step is provided with a tapered groove 10, and the two ends of the tapered groove 10 on the groove step plane are arranged side by side. The middle layer of the trough 10 is provided with cup-shaped foundation reserved prestressed steel holes 9 side by side; the cup-shaped foundation reserved energy-dissipating steel holes 8 and the cup-shaped foundation reserved prestressed steel holes 9 are parallel structures.

[0032] The frame column 5 is a cylindrical...

Abstract

The invention relates to a novel post-earthquake self-reset concrete framework-eccentric supporting structural system, and belongs to the technical field of earthquake prevention and disaster reduction. The initial rigidity of an embedded type cup-shaped foundation is basically the same as the rigidity of a cast-in-place concrete structure, under the condition of a small interlayer displacement angle, prestressed steel keeps elasticity, energy consummation steel bars enter the plastic state to dissipate energy, and the embedded type cup-shaped foundation can reset to the initial position after the earthquake action. Compared with the prior art, the novel post-earthquake self-reset concrete framework-eccentric supporting structural system overturns a traditional concrete structural building foundation, and basically solves the difficult problems that concrete structures are not easy to assemble and poor in ductility. Compared with the traditional concrete structural foundation, the novel post-earthquake self-reset concrete framework-eccentric supporting structural system has the advantages of being high in safety performance, small in environmental pollution, few in accident, low in manufacturing cost of projects and the like.

Description

technical field [0001] The invention relates to a novel post-earthquake self-resetting concrete frame-eccentric support structure system, which belongs to the technical field of earthquake prevention and disaster reduction. Background technique [0002] The collapse of building structures in earthquakes is the most important reason that threatens people's lives and causes property losses. The Wenchuan and Ya'an earthquakes showed that concrete structures have poor seismic performance and weak foundations. At present, concrete structures are the main building structure forms in my country, especially the technology of prestressed concrete structures is at the international advanced level. The application of prestressed technology can reduce the deflection of beams and increase The span of the beam can also have the effect of self-resetting after the earthquake. Making full use of the advantages of prestressing technology and applying it to the concrete frame foundation will i...
