| Abstract: | The pseudo-static test on the longitudinal frame model of 3 stories and 3 spans with energy-dissipation braces is carried out.The experimental summary is briefly introduced.On the basis of experimental results,the deformation performance and ductility of the model structure are studied.Strengthening measure for weak story is put forward.The results indicate that the structure is of good ductility and energy-dissipation capacity,which meets the requirements of code.A method and a simplified formula for the determination of the stiffness parameter are proposed.Some recommendations to seismic design are presented for the sake of advanced theoretical analysis and engineering practice. |
