Annular box type energy dissipation reticulated shell joint

Abstract

The invention relates to an annular box type energy dissipation reticulated shell joint and belongs to the building technical field. The annular box type energy dissipation reticulated shell joint is composed of an inner cylindrical reinforcing plate, outer polygonal reinforcing plates, side rib energy dissipation steel plates, horizontal rib energy dissipation steel plates and installation cover plates, wherein the inner cylindrical reinforcing plate is arranged at the center, the outer polygonal reinforcing plates are arranged outside the inner cylindrical reinforcing plate, the side rib energy dissipation steel plates are arranged between the inner cylindrical reinforcing plate and the outer polygonal reinforcing plates, the inner cylindrical reinforcing plate and the outer polygonal reinforcing plates are of the same height, the horizontal rib energy dissipation steel plates are arranged on the bottom, in the middle and on the top of the inner cylindrical reinforcing plate and on the bottom, in the middle and on the top of each outer polygonal reinforcing plate, and the installation cover plates are arranged on the bottom and top of the inner cylindrical reinforcing plate and on the bottom and top of each outer polygonal reinforcing plate. The joint has the advantages that initial rigidity is quite high, energy dissipation effect is good, no obvious stress concentration phenomenon occurs, manufacturing and installation are easy, and using is convenient.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a ring-box type energy-dissipating reticulated shell node for vibration control of building structures. Background technique [0002] The reticulated shell is a space bar structure similar to the flat grid. It is based on bars, forms a grid according to certain rules, and is a space frame arranged according to the shell structure. It has the properties of bar systems and shells. The characteristic of its force transmission is mainly to transmit force point by point through the tension, pressure or shear force in two directions in the shell. This structure is a spatial structure that has attracted much attention at home and abroad and has broad development prospects. [0003] The development of the reticulated shell structure and a large number of engineering practice applications provide a novel and reasonable structural form for the building structure, mainly because the reti...
