The present work consists of the analysis and design of the steel foundations of the Begonias and Westin Libertador buildings, located in Lima, Peru. These buildings have a peculiar foundation (foundation platforms with cants greater than 2 meters), which present a core structure also called ''corewall'', in which the structural system is made up of shear walls, columns and reinforced concrete elevator boxes. From the modeling of the structures in the ETABS program, thanks to the original plans of the buildings, the ultimate loads that reach the foundation have been determined using all the combinations of the Peruvian technical standard E.060. The ''strut&tie'' methodology allows us to identify the internal behavior of the concrete (internal forces of traction and compression) based on the modeling of reinforcements in the body of the foundation. The reinforcement configurations are based on the points where the loads fall and on the limits of the foundation that are proposed in the original plans. For this study, the steel reinforcement of the foundation will be analyzed, considering the internal forces of the reinforcement proposed with the "strut&tie" methodology, with these results and with the yield stress of the steel, it is possible to determine the area of steel that satisfies the internal force. Once the steel reinforcement was determined, the design amounts were determined, which were less than the design amounts of the original reinforcement (for the two buildings). Consequently, the ratios of steel to the volume of concrete were also lower and finally the price analysis favored the steel design by the “strut&tie” methodology.
