A design method of steel structure system with prestressed column falcon connection

Abstract

The invention provides a prestress column tenon connection steel structure system and a design method thereof. The prestress column tenon connection steel structure system comprises at least two layers of steel-frame structures stacked in the vertical direction; steel columns of each layer of the steel-frame structure are broken at the connecting parts between the steel columns and the lower layers of floor slabs; adjacent steel-frame structures are connected through prestress column tenon connection structures; the prestress column tenon connection structures comprise through holes, top sleeving tenons, elastic materials and high-strength pulling cables; the through holes are formed in the tops of the steel columns of the lower layers of the steel-frame structures; the top sleeving tenonsare connected with the bottoms of the steel columns of the upper layers of the steel-frame structures; the top sleeving tenons at the bottoms of the steel columns are correspondingly inserted into the through holes in the tops of the steel columns; gaps are reserved between the side walls of the top sleeving tenons and the side walls of the through holes; gaps are reserved between the tops of thethrough holes and the bottoms of the steel columns of the upper layers of the steel-frame structures; the elastic materials are arranged in the gaps between the top sleeving tenons and the through holes; and the high-strength pulling cables penetrate through the steel columns vertically corresponding in the steel structure system. The technical problem that a traditional steel structure is low inconstruction efficiency, severe in environmental pollution and poor in connecting joint anti-seismic property is solved.

Description

Technical field[0001]The invention belongs to the technical field of structural engineering, in particular to a design method of a steel structure system connected by prestressed columns and falcons.Background technique[0002]Fabricated steel structure building refers to a building assembled from prefabricated parts and components on the site. It has many advantages such as fast construction speed, less restricted by climatic conditions, labor saving, and improvement of building quality. It is currently being vigorously promoted; however, the current assembly steel Most of the structural buildings use bolted or welded connections, which reduces the construction efficiency to a certain extent and causes environmental pollution; and the bolted or welded connections are rigid connections, and the energy consumption performance of the connection nodes is poor, and the steel structure system is relatively seismic low.Summary of the invention[0003]The purpose of the present invention is to...
