Problems solved by technology

However, several major earthquake disasters at home and abroad in recent years and studies have shown that after the traditional steel frame structure has experienced strong earthquakes, significant residual deformation will remain in the structure, and the subsequent "repair" or "demolition-reconstruction" work will become a formidable challenge

Abstract

The invention discloses an assembly type conical special-shaped steel pipe column foot with a restorable function and an assembly method. The column foot comprises a box-shaped foundation, a conical special-shaped steel pipe short column, an I-shaped steel column, semi-arc angle steel, prestressed cables and special-shaped soft steel ring springs; and the box-shaped foundation is connected with the semi-arc angle steel through high-strength bolts, the conical special-shaped steel pipe is provided with vertical long circular bolt holes and connected with the semi-arc angle steel through high-strength bolts configured with the special-shaped soft steel ring springs, the outer side conical curved surface pipe wall is tightly combined with the inner side conical curved surface of the semi-arcangle steel to form a wedge-shaped friction pair, the special-shaped soft steel ring springs are tightly combined with the contact faces, the conical special-shaped steel pipe short column and the I-shaped steel column are connected through high-strength bolts, and the box-shaped foundation and the I-shaped steel column are connected through the prestressed cables to achieve a self-resetting function. According to the column foot and the method, the assembly degree is high, the use function of the column foot can be rapidly recovered by replacing a small number of damaged elements after an earthquake, meanwhile, the self-resetting function is achieved, and a replaceable structure system and a self-resetting system are combined.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled conical special-shaped steel pipe column foot with a recoverable function and an assembly method. Background technique [0002] The steel frame structure is an effective anti-seismic system. In order to achieve better anti-seismic performance at a relatively low economic cost, the traditionally designed building steel structure undergoes inelastic deformation under strong earthquakes and prevents the structural system from being damaged by earthquakes. The collapse below is the fundamental starting point. However, several major earthquake disasters at home and abroad in recent years and studies have shown that after the traditional steel frame structure has experienced strong earthquakes, significant residual deformation will remain in the structure, and the subsequent "repair" or "demolition-reconstruction" work will become a formidable challenge. ...
