Análisis estructural y diseño de reforzamiento de dos viviendas adosadas ante amenaza sísmica

Abstract

This technical project focuses on the study of the reinforcement of two townhouses of informal construction located in the north of Quito. The structural system of both dwellings consists of reinforced concrete frames, band beams, slabs and block masonry walls. Based on an inspection and seismic evaluation of the structures under study, it was determined that both houses are highly vulnerable. In situ and laboratory tests are used to determine the properties of the soil and materials. With the help of computer programs, the two houses are modeled using Link-Gap elements that simulate the interaction between the two structures to determine their modal behavior. The results of the behavior of the two houses are obtained and it is determined that both require reinforcement to comply with the requirements established by the NEC-15. It is established that veneer is the best option for the reinforcement and that the two houses should be joined in order not to change their architecture. By veneering the walls, the requirements established by the NEC are met. Structural plans are generated and a referential budget is given for the reinforcement.
