A dual-function shock-absorbing support structure for liquid storage tanks

Abstract

The invention relates to a dual-function shock-absorbing support structure for a liquid storage tank, which includes a plurality of columns made of section steel, the bottom ends of each column are welded to the bottom end of the liquid storage tank, and the support structure also includes a pedestal and energy-dissipating components , the number of pedestals and energy-dissipating components is the same as the number of columns. One end of each energy-dissipating component is connected to the outer surface of the corresponding column, and the other end is connected to the corresponding pedestal. Each pedestal is fixed on the installation foundation. Horizontal restraint steel plates are connected between adjacent columns, and each horizontal restraint steel plate is horizontally installed on the installation foundation and embedded into the grooves of the connected columns. Compared with the prior art, the present invention can reduce the seismic response of the supporting liquid storage tank structure, improve its anti-seismic performance, facilitate disassembly and replacement after a disaster, quickly restore the normal use of the liquid storage tank, and have the advantages of not being damaged by small earthquakes, The double function that can be replaced by a big shock.

Description

technical field [0001] The invention relates to the technical field of material storage and transportation, in particular to a dual-function shock-absorbing support structure for a liquid storage tank. Background technique [0002] In order to meet the increasing energy storage and demand, liquid storage tanks are widely used in practical projects. Due to the flammable and explosive properties of LNG, the construction and design of liquid storage tanks have strict requirements. The construction of large liquid storage tanks has become a development trend with the continuous advancement of technology. my country is located in the volcanic seismic belt around the Pacific Ocean, and most of the petrochemical industry is located in the earthquake area. As a sudden and highly harmful natural disaster, an earthquake may cause damage to the structure of the LNG storage tank, fire, Secondary disasters such as environmental pollution and explosions cause casualties and huge economic ...

AI Technical Summary

Problems solved by technology

The structural system has no energy-dissipating components, and it is prone to damage under earthquake loads. There are mainly two forms. One is that the tank wall at the welded part of the pillar and the tank body will undergo yield damage, and the other is that the pillar will undergo bending damage. Both will enter the plastic stage and cannot be repaired, and the liquid storage tank cannot continue to be used
