Problems solved by technology

From the perspective of seismic engineering, the material requirements for building structures are high rigidity, high strength and high elastic-plasticity. Stiffness and elastic-plasticity are a pair of contradictory factors. The existing building structure materials have high strength and rigidity, but elasticity, The plasticity is low, and the strength and stiffness of structural materials with high elasticity and plasticity cannot meet the requirements. Traditional building structural materials cannot solve this contradiction. This is the problem existing in traditional building structural materials from the perspective of earthquake resistance engineering.

Abstract

The invention relates to an anti-seismic composite material and its manufacturing method. The material is a high-rigidity, high-strength and high-elasticoplastic material and it consists of steel member in a radial arrangement and members with the shock-absorbing performance. The number of two members can be same, or the number of the steel member is more than the number of the members. The method of manufacturing the anti-seismic composite material includes the following steps of preprocessing the steel members; welding the steel members to a box model; pouring melted material liquid with the shock-absorbing performance into the model by casting method and forming by cooling.

Description

technical field [0001] The invention relates to an anti-seismic composite material, in particular to an anti-seismic composite material used in the field of construction and walking machinery. The invention also relates to a method of manufacturing such an anti-seismic composite material. Background technique [0002] At present, the materials used in building structures require high strength and rigidity, and the damage to buildings caused by earthquake force will increase with the increase of the bearing capacity and stiffness of building structures. From the perspective of seismic engineering, the material requirements for building structures are high rigidity, high strength and high elastic-plasticity. Stiffness and elastic-plasticity are a pair of contradictory factors. The existing building structure materials have high strength and rigidity, but elasticity, The plasticity is low, and the strength and stiffness of structural materials with high elasticity and plastici...
