Creep strain behaviour under seismic loads in reinforced concrete silos at high temperatures

This study investigates the creep behavior of a typical concentric conical hopper concrete silo used in Guerrero, Mexico, at high temperatures, comparing its response under static and seismic loading conditions. Primary creep deformation over 210 days was analyzed using the Time-Hardening Law, followed by a 20-year secondary creep analysis using Norton’s Power Law. Seismic loads were simulated through time-history analysis using a synthetic acceleration signal. The results, along with the comparison between seismic and non-seismic scenarios, highlight the significant influence of seismic events on long-term creep deformation and stress redistribution in concrete silos, with implications for the design and maintenance of these structures in seismically active regions.
