Variable-rigidity variable-damping building joint internal energy dissipation device
The invention discloses a variable-rigidity variable-damping building joint internal energy dissipation device. The variable-rigidity variable-damping building joint internal energy dissipation devicecomprises an internal stress bearing platform and left and right stress frames which are arranged on the two sides of the internal stress bearing platform in a sleeving mode, bent steel sheets are arranged between the internal stress bearing platform and the left and right stress frames in a connected mode, the left stress frame and the right stress frame are connected through a plurality of setsof springs which are arranged on the left stress frame and the right stress frame, the springs are fixedly connected with the left stress frame and the right stress frame through thin wire ropes which are arranged at the end parts of the springs correspondingly; sliding blocks are arranged on the stress frames correspondingly, independent sliding rails corresponding to the sliding blocks are arranged on the internal stress bearing platform correspondingly, limiting ends are arranged at the two ends of each sliding rail correspondingly; and spring pieces are connected between the sliding blocks and the corresponding limiting ends close to the end part of the internal stress bearing platform. The variable-rigidity variable-damping building joint internal energy dissipation device can bear loads in the horizontal direction and the vertical direction at the same time, resist a certain bending moment effect and achieve staged changes of damping and rigidity in the horizontal direction so as to cope with the effect of external input energy with different magnitudes.
