A kind of dk-type space converging node formed by welding box-shaped steel pipes and its application

Abstract

The invention discloses a DK-type space confluence joint formed by welding box-shaped steel pipes, which comprises a main partition stiffening plate assembly, butt joints of oblique column members, steel beam bolt welding joints and internal vertical support stiffening ribs. The main partition and stiffener assembly is a central support frame, which separates the butt joints of the slanted column members and the steel beam bolt welding joints from each other; the butt joints of the slanted column members are box-shaped steel pipe joints composed of welded plates, and The main partition stiffener assembly is butt welded; the steel beam bolt welding joints are located on both sides of the node horizontally, and rigid bolts are welded to the main partition stiffener assembly; the internal vertical support stiffeners are located inside the main partition stiffener assembly , as a local lateral support of the plate inside the node. The present invention is based on the section replacement technical scheme and nonlinear instability damage limit analysis. Its node plates have clear composition modules and clear force transmission. At the same time, it ensures better seismic performance and higher anti-lateral bearing capacity, and has a wide range of applications. .

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a DK-type space junction formed by welding box-shaped steel pipes. Background technique [0002] The slanted column system is a spatial vertical network structure composed of multi-directional crossed and regularly arranged slanted column components on the outer surface of the building circle. Due to its novel outer surface shape and great overall lateral stiffness, it is mainly used in Slanted column-frame tubes in super high-rise buildings. [0003] The huge lateral stiffness of the outer slanted column frame enables it to withstand extremely large horizontal loads (earthquakes, wind loads, etc.), and the effective lateral stiffness of the inner core tube can be reduced by weakly connected beams under the premise that the total horizontal force remains unchanged. The connection is appropriately reduced, and the room arrangement based on the building ...
