Analysis Study On Performance Of Energy Dissipation Structure System Of Modular Container Building

As a kind of prefabricated building form and its special architectural aesthetics,container building has set a high application boom and research heat in the world.This type of building conforms to the current development trend of our country and has a high application range.It is a development direction that cannot be ignored in prefabricated buildings.The connection node of the container building is a key factor to ensure the structural integrity,and it is also an important limitation of the current application scope of container construction.At the same time,the research on the seismic performance of container buildings is carried out less.The seismic design methods for container buildings are incomplete,there are no specific construction measures,and specific guidance schemes cannot be given in the structural design.This paper sorts out the problems existing in the current stage of modular container construction,and proposes a modular container damping structure system,and proposes a modular container damping connection node.The main research contents include the following aspects:Based on the common nodes of container construction,combined with the idea of ??seismic isolation,a shock-absorbing connection node for container construction was designed,and the finite element modeling was carried out for the proposed damping connection node.A conventional connection node analyzes the feasibility of the connection form and obtains its basic seismic performance.On the basis of the proposed shock-absorbing connection node,it is placed in a modular container building to form a shock-absorbing structure system.The finite element modeling of the conventional structure and the shock absorbing structure is carried out,and the seismicperformance of the conventional structure and the shock absorbing structure are obtained respectively.The performance parameters under different structural forms are revealed,and the comparative analysis is carried out to discuss the seismic performance of the shock absorbing structure.Improvement range and seismic performance of the shock-absorbing connection node.When used as a building,the used container will be modified in advance to further improve the structural strength and lateral stiffness of the box itself,or to open the hole in the side plate of the box in order to meet the needs of the building,or even remove it.The entire side panel,so for different transformation measures,the container building after the box transformation is modeled,revealing the seismic performance of the shock absorbing structure system and the conventional structural system,the internal force transmission path,the damping connection node and the box module unit The cooperative working mechanism between components.
