| Abstract: | The viscoelastic energy dissipative brace was applied to lattice roof-structure for seismic control in this paper.The equation to calculate the damping ratio of the structure and the equation to estimate the control effect were established successively according to single mass point model.And the mode decomposition response spectrum method or the time history analysis method was suggested for detailing design.Two specific projects were taken as examples for numerical analysis.The results indicated that the ... |
