Abstract

The invention discloses an energy dissipation and shock absorption node for a steel structure. The energy dissipation and shock absorption node comprises a connecting block and a wedge-shaped body, wherein the left side of the connecting block is fixedly connected to a steel column; a wedge-shaped groove with the opening direction facing to the right is formed in the right side of the connecting block; the distance between upper and lower wedge-shaped groove walls of the wedge-shaped groove is gradually reduced from right to left; the wedge-shaped body is positioned in the wedge-shaped groove;the right side of the wedge-shaped body is fixedly connected with a steel beam; the left side of the wedge-shaped body is in contact with the groove bottom of the wedge-shaped groove; the distance between the upper wedge-shaped surface and the lower wedge-shaped surface of the wedge-shaped body is gradually reduced from right to left; the wedge-shaped groove walls are connected with the corresponding wedge-shaped surfaces through elastic sheets; the corresponding wedge-shaped groove walls, wedge-shaped surfaces and elastic sheets jointly form a closed space; the closed space is filled with damping materials; and the upper side and the lower side of the connecting block are respectively connected with the corresponding sides of the steel beam through at least one anchor cable. The energy dissipation effect can be achieved through a damping energy dissipation mechanism, deformation of the beam column can be effectively prevented, and the purposes of energy dissipation and shock absorption can be achieved.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to an energy-dissipating and shock-absorbing node for steel structures. Background technique [0002] Earthquake, as one of the natural disasters, seriously affects the life of building structures. Due to the complex force of the joints, the damage and destruction of the joints are the most serious in previous earthquake damages, and the damage of the joints often leads to the continuous collapse of the structure. Therefore, the design of the joints is the key to the seismic design of the structure, and the traditional steel structure joints, The "hard resistance" design method of "strong nodes and weak components" is often used in the design, and the plastic hinges appear in the beams and columns by making strong nodes, so as to consume the energy of the earthquake, so that the joints of beams and columns are damaged due to the appearance of plastic hinges. Deformation of...
