| Sumario: | Reinforced concrete buildings subjected to seismic events may present different damages even though they have similar characteristics when designed with the regulatory seismic load combination. This results in higher costs and inconsistent structural reliability over the life cycle of the buildings. This work focuses on comparing the life cycle costs of reinforced concrete buildings of various levels located on soil with period Ts=0.75s and Ts=2.0s in Mexico City. For this purpose, a set of seismic load combinations proposed for the design of the buildings were used. The capacity of the designs was evaluated by incremental dynamic analysis and the structural reliability was examined by structural demand hazard curves. In addition, simulations of seismic demands were performed to estimate the damage that could occur during the life cycle of the buildings. Finally, initial and total damage costs were obtained for all the buildings analyzed. The results showed that some proposed load combinations provided cost savings while improving the structural performance of the buildings over time. These findings could be valuable to the construction industry, as they offer a clearer picture of how to optimize the design and seismic resistance of buildings. |
