Prestress column tenon connection steel structure system and design method thereof

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 steel structure system connected by prestressed column falcons and a design method thereof. Background technique [0002] Prefabricated steel structure buildings refer to buildings assembled from prefabricated parts and components on site. They have many advantages such as fast construction speed, less restriction by climatic conditions, labor saving, and improvement of construction quality. They are currently being vigorously promoted; Most of the structural buildings are connected by bolts or welds, which reduces the construction efficiency to a certain extent and causes environmental pollution; and the bolts or welds are rigid connections, the energy dissipation performance of the connection nodes is poor, and the seismic resistance of the steel structure system is relatively low. Low. Contents of the invention [0003] The object of the present invention i...
