Abstract

The invention discloses a novel all-dimensional twisting energy dissipation damping supporting seat. The novel all-dimensional twisting energy dissipation damping supporting seat includes a base and atop seat, the base is provided with at least three energy dissipation supporting columns, the energy dissipation supporting columns are provided with limiting parts which are connected with the base,and the energy dissipation supporting columns are connected with connecting parts which are rotatably provided with sliding blocks in a connecting mode; each of the sliding blocks is suitably matchedwith a corresponding sliding groove, the sliding grooves are connected at the lower surface of the top base, and the sliding blocks can slide in correspondence with corresponding sliding grooves; andthe sliding grooves are located at the same plane, at least two sliding grooves are not mutually parallel, and the energy dissipation supporting columns are mild steel members. According to the novelall-dimensional twisting energy dissipation damping supporting seat, the principle of a traditional supporting seat energy dissipation due to friction can be broken, deformation capability of materials can be fully played, earthquake kinetic energy amount can be effectively consumed, the blindness and the directionality in present designing and installing process can be avoided, the energy dissipation effect of the supporting seat is improved, and the entire anti-quake performance and safety of a structure can be improved.

Description

technical field [0001] The invention relates to the field of bridge anti-seismic technology, in particular to a novel all-round torsional energy-dissipating damping support. Background technique [0002] my country is one of the countries with the strongest seismic activity and the worst earthquake disasters in the world. With the vigorous development of transportation in our country, there are many high-speed railways planned or constructed especially in the western mountainous area and the eastern coast. The proportion of bridges in the line is However, due to the generally large span of bridges, in the event of disasters such as earthquakes and strong winds, bridges often appear torsion, pull, subsidence, overturning and other phenomena, resulting in damage. The damage and collapse of bridges in earthquake areas not only hinders the current Disaster relief operations, but also affect the restoration and reconstruction of bridges after the disaster. [0003] In the prior ar...
