Embodiment 1

[0026] Such as Figure 1 to Figure 5 As shown, a density gradient seismic building structure includes an excavated foundation 1, an anchor rod 3, a density gradient material 2 fixed on the slope of the excavated foundation 1 and the inherent foundation 10, and the density gradient material 2 The corners are bonded, welded or bolted 5 connections. It also includes a foundation lining 4, which is laid on the top of the density gradient material 2 fixed on the plane of the inherent foundation 10 and inside the density gradient material 2 fixed on the side slope of the excavated foundation 1 .

[0027] After the excavation of the foundation is completed, the slope of the foundation is leveled and the initial lining treatment is carried out; after the treatment is completed, the density gradient material 2 is closely attached to the periphery of the foundation and the surface of the inherent foundation 10 of the foundation, and the fixed surface of the excavated foundation 1 The d...

Abstract

The invention relates to a density gradient anti-seismic building structure, and belongs to the technical field of building structure anti-seismic projects. The density gradient anti-seismic buildingstructure comprises an excavated foundation, anchor rods and density gradient materials, wherein the density gradient materials are fixed to the foundation slope and the inherent base plane of the foundation through the anchor rods. The corner positions of the density gradient materials are bonded, welded or connected through bolts. The density gradient materials are composed of nonmetal-nonmetal,nonmetal-metal or metal-metal. The density gradient materials at least comprise four levels including first-level density materials, second-level density materials, third-level density materials andfourth-level density materials. According to the density gradient anti-seismic building structure, anti-seismic protection is directly implemented on the building structure foundation slope and the inherent base of the foundation, the complex technology that anti-seismic materials are added in a building structure is avoided, consumption of the anti-seismic materials is reduced, the self weight ofthe building structure is not changed, and the integral safety of the building structure can be better improved.

Description

technical field [0001] The invention relates to a density gradient anti-seismic building structure, which belongs to the technical field of anti-seismic engineering of building structures. Background technique [0002] my country is one of the most earthquake-prone countries in the world. About 70% of the large and medium-sized cities are located in earthquake zones above magnitude 7. Seismic activities are mainly distributed in 23 seismic zones in 5 regions. Therefore, how to find a safe and efficient method of seismic strengthening of building structures plays an extremely important role in earthquake resistance and disaster reduction. At present, there are three main methods to enhance the seismic capacity of buildings: (1) Seismic reinforcement, which uses measures such as enhancing the bearing capacity, deformation capacity, integrity of each component of the structure and improving the way of force transmission to resist earthquake action and absorb earthquake energy. ...
