Seismic behavior of telescopic buckling braced frame structure

A telescopic buckling brace was investigated. The design method for the brace was established, and finite element simulations were conducted. The simulation accuracy was validated against the existing test results, and an elastoplastic dynamic time history analysis method was used to study the seismic performance of the telescopic buckling brace frame structure. The results showed that under the action of strong earthquakes, compared with ordinary braced frame structures, the shape of the base shear-vertex displacement hysteresis curve of the telescopic buckling frame structure was relatively full, the seismic energy dissipation capacity was increased by 34 %, and the base shear force of the structure was reduced by 23 %. The maximum floor displacement and the maximum story drift angle of the structure were reduced by 20 %.
