Connection joint between endplate type concrete-filled steel tube column and steel beam with internal reinforcement ring

Abstract

The invention discloses a connection joint between an endplate type concrete-filled steel tube column and a steel beam with an internal reinforcement ring. The connection joint comprises a concrete-filled circular steel tube column, a steel beam, an endplate, bolts and an internal reinforcement ring. The connection node is high in stressing performance and high in seismic performance, simple in structure, clear and definite in force transfer and quick to construct; the structural layout is facilitated; the problem that the high-strength bolts are not liable to construct can be solved; the connection joint is not required to be welded on site; the connection joint is liable to dismount and replace; the connection joint is a novel concrete-filled steel tubular column-steel beam rigid connection joint.

Description

technical field [0001] The invention relates to the field of structural engineering connection nodes, in particular to an end-plate type steel pipe concrete column and steel beam connection node with an inner reinforcing ring. technical background [0002] Before the 1980s, most of the high-rise buildings in my country used reinforced concrete structures. However, with the increase in height and number of floors, the use of building functions has become increasingly complex. Concrete structures or pure steel structures can no longer meet the requirements of functional functions. Facing the huge challenge of high-rise and super-high-rise buildings, concrete-filled steel tube structures are increasingly being used in high-rise building structures due to their excellent performance. However, the research on joints between concrete filled steel tubes and steel beams is far less thorough than the research on joints between steel columns and steel beams. Therefore, research on mor...
