Szukana fraza: [Abstract = "The elastic response spectrum analysis \(RSA\) and direct integration nonlinear time history analyses \(NL\-TH\) are carried out for the frame structure before and after reinforcement using ETABS finite element software. From the joints displacement, inter\-story displacement, inter\-story shear force, acceleration, energy dissipation, and other aspects of the seismic response of the strengthened structure and the non\-strengthened structure, the comparison has been made."]
