Assembled column pestle connected steel structure system and design method thereof

Abstract

An assembled column pestle connected steel structure system and a design method thereof comprise at least two layers of steel frame structures which are vertically stacked; the steel columns of the two vertically adjacent layers of steel frame structures are disconnected with a floor slab at the lower layer, and the steel columns between the two adjacent layers of steel frame structures are connected through a pestle; the top of each steel column in the lower steel frame structure is provided with a mortise; the bottom surface of the mortise is a concave curved surface which is sunken downwards, and the top of the mortise is provided with a clamping edge; the bottom of the steel column in the upper-layer steel frame structure is provided with a tenon, and the bottom surface of the tenon isconvexly curved; the tenon at the bottom of the upper-layer steel column is correspondingly inserted into the mortise at the top of the lower-layer steel column, a space is reserved between the tenonand the clamping edge, and a space is reserved between the top of the mortise and the bottom of the upper-layer steel column; the vertical side wall of the tenon is provided with a spring block; andan elastic component which ejects an elastic block is arranged in the tenon. The assembled column pestle connected steel structure system solves the technical problems of complex structure, poor construction efficiency, poor seismic energy dissipation performance and poor seismic performance of the traditional assembled steel structure building node.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, in particular to a steel structure system connected by an assembled column and pestle and a design method thereof. Background technique [0002] The prefabricated steel structure building is based on the industrial construction method, and the parts and components are produced in a factory and assembled on site. With many advantages such as high construction efficiency, low environmental pollution, detachable, recyclable and easy maintenance, it has become a main theme of future architectural development. However, most of the current assembled steel structures are connected by bolts or welds, which reduces the construction efficiency to a certain extent; Low seismic performance. Contents of the invention [0003] The purpose of the present invention is to provide a steel structure system and its design method of assembled column and pestle connection, to solve the technical pro...
