Preliminary Research

With the extensive use of HSC in the tall building and super high-rise building, the harm of HSC subjected to fire has also been increasing. For the concrete structure in the seismic region after fire, its seismic performance after repair directly relates to the structure safety under the action of possible earthquake in the future. Based on the experimental data in the preliminary research, seismic response analysis on the repaired HSC structure after fire was made according to the principle of uniform section. The results indicate that the seismic performance of HSC frame structure repaired by the principle of uniform section can be restored to the level before fire. But we should pay more attention to the interlaminar maximum displacement of fire storey, which should be partly strengthened when necessary.

A parametric study of nonlinear seismic response analysis of transmission line structures subjected to earthquake loading is studied in this paper. The transmission lines are modeled by cable element which accounts for the nonlinearity of the cable based on a real project. Nonuniform ground motions are generated using a stochastic approach based on random vibration analysis. The effects of multicomponent ground motions, correlations among multicomponent ground motions, wave travel, coherency loss, and local site on the responses of the cables are investigated using nonlinear time history analysis method, respectively. The results show the multicomponent seismic excitations should be considered, but the correlations among multicomponent ground motions could be neglected. The wave passage effect has a significant influence on the responses of the cables. The change of the degree of coherency loss has little influence on the response of the cables, but the responses of the cables are affected significantly by the effect of coherency loss. The responses of the cables change little with the degree of the difference of site condition changing. The effect of multicomponent ground motions, wave passage, coherency loss, and local site should be considered for the seismic design of the transmission line structures.
