[摘要]對四川耿達(dá)小學(xué)教學(xué)樓結(jié)構(gòu)進(jìn)行了基礎(chǔ)隔震設(shè)計,并采用靜力等效側(cè)力法和時程分析法對隔震結(jié)構(gòu)和非隔震結(jié)構(gòu)進(jìn)行對比分析。結(jié)果表明,隔震結(jié)構(gòu)能明顯減小結(jié)構(gòu)的地震反應(yīng),改善結(jié)構(gòu)的抗震性能,提高結(jié)構(gòu)的延性。最后,提出了隔震層的連接構(gòu)造措施。

Abstract: A base isolation design for teaching building of Sichuan Gengda primary school was carried out. Comparative analysis of the isolated structure and non-isolated structure was conducted through the static equivalent lateral force method and time history analysis method. The results show that the isolated structure can significantly reduce the seismic response,improve the seismic performance and increase the ductility of the structure. Finally, the structural connection measure of the isolation layer was proposed.
Keywords: isolation performance; rubber bearing isolator; seismic response
