Abstract

To investigate the dynamic response of the frame structure of the skid-mounted substations with electronic control reinforced by buckling-restrained braces (BRBs) under high-intensity earthquake and wind loads, the study utilized the Plastic (Wen) connection element in SAP2000 finite element software to simulate the behavior of the BRB structure, and the response spectrum and nonlinear time history analyses were conducted. These analyses demonstrate that the original substation structure maintains its safety during frequent earthquakes and wind loads. Upon encountering exceptionally strong earthquakes, the structure exhibited significantly increased lateral inter-story displacement angle. After reinforcement with BRB devices, the lateral inter-story displacement angle during rare seismic waves showed a 53% reduction relative to the unfortified structure, accompanied by a 13% decrease in base shear force. Under the 10-level wind load, the utmost lateral displacement diminished by 44%, and the peak stress saw a 37.5% reduction. The inclusion of BRBs notably dissipates the energy of earthquakes and wind loads, which provides a reference for designing substations that withstand such external disaster conditions.
