Abstract:
Through time history analysis under single-component earthquake excitations, the deficiencies of the seismic performance of the exiting structural system of air-cooled condenser were pointed out. Comparisons between the structural system with and without buckling-restrained braced(BRB)supporting systems were carried out. The mechanical behaviors of BRB structural system of air-cooled condenser under two-component earthquake excitations were preliminarily studied, and a connecting procedure of the super-long BRB was proposed. The results show that the influences of overall torsion deformation under earthquake excitations are prohibited efficiently by adding BRB to the existing structural system of air-cooled condenser, and the torsion deformation has an increase trend after yielding of the BRB in two-component arrangement of the structural system.
