Composite steel pipe UHPC damping column pier

Abstract

The invention relates to the technical field of civil engineering, and especially relates to a composite steel pipe UHPC damping column pier. The composite steel pipe UHPC damping column pier is composed of an external steel pipe, an internal steel pipe, an UHPC layer and a rubber concrete layer; the internal steel pipe is sleeved in the external steel pipe, a part between the inner wall of the external steel pipe and the outer wall of the internal steel pipe is filled with the UHPC layer, and an internal part of the internal steel pipe is filled with the rubber concrete layer. The composite steel pipe UHPC damping column pier uses the advantages of steel pipe, UHPC and the rubber concrete, can better solve the anticorrosion problem of the steel pipe concrete, increases the endurance of amember, reduces the life-cycle cost of the member, and prolongs the life period of the member; the damping column pier has the advantages of energy saving and environmental protection, accords with continuous development requirement of green building idea and building industry; the member has the advantages of large carrying capacity reserve, good ductility, seismic performance and fatigue resistance, excellent shock resistance, and good damping performance, and has excellent seismic performance and good damping capability.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a composite steel pipe UHPC shock-absorbing pier. Background technique [0002] my country is one of the countries that produce the largest amount of waste rubber tires, and its consumption of rubber resources ranks among the top in the world. According to relevant data predictions, by 2020, the generation of waste rubber in my country will reach more than 6 million tons. Waste rubber is not easy to degrade, and it will pollute the environment after landfill, and incineration will bring air pollution. Simultaneously, if waste rubber can not be rationally utilized, it will also cause a waste of effective energy. The disposal of waste rubber and how to reasonably solve the resource utilization of waste rubber have become urgent problems to be solved. [0003] Rubber aggregate concrete is a new type of green environmental protection building material made by mixing rubb...

Problems solved by technology

[0007] At present, the earthquake resistance of buildings mainly depends on the strength and stiffness of structural components, resulting in excessive structure weight, resulting in excessive use of building materials, resulting in resource shortages, high engineering costs, and to a certain extent, affecting the aesthetics and functions of buildings.

The practice of resisting earthquakes by increasing the rigidity and strength of the structure does not meet the requirements of sustainable development of the construction industry
