Diseño sostenible de la ampliación de una edificación de cuatro niveles y análisis integral de su desempeño sísmico

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The objective of this project is to carry out the structural design and comprehensive seismic analysis of the expansion of a four-story building in Guayaquil, Ecuador. The working hypothesis holds that the choice of sustainable materials, such as ecological concrete and recycled steel, along with a detailed seismic performance evaluation, will ensure the safety and efficiency of the design. This study is relevant for demonstrating how structural solutions adapted to seismic standards can improve the resilience of existing buildings. For the development of the project, a detailed technical survey of the existing structure was conducted due to the lack of original plans. Structural calculations were then made using specialized software and local seismic standards were applied. Two structural alternatives were evaluated: the first using ecological concrete and the second using recycled steel. In both cases, basal shear, period, and drift analyses were conducted, adhering to the safety parameters established by the standards. The results show that both alternatives meet the seismic resistance requirements, without exceeding deformation limits and with adequate structural loads. Recycled steel, due to its lightweight nature, proves to be a favorable option as it does not impose additional loads on the existing foundation. In conclusion, the proposed structural expansion ensures the seismic safety and sustainability of the building, complying with the current standards. The choice of recycled steel is recommended for its low impact on the foundation and its structural performance. Keywords: Seismic evaluation, structural expansion, sustainability, seismic resistance
