Seismic Response Analysis on the Repaired HSC Structure after Fire

Abstract:

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.
