Abstract: Design Optimality of RC Buildings “that merges the perspective of design and construction” is a goal for each designer. This paper aims to compare between different structural systems that are commonly used as Lateral Force-Resisting Systems (LFRS) and choose the optimum structural system for each height and aspect ratio under the action of gravity and earthquake loads from the perspective of value engineering. This paper proposes three different feasible solutions for the selection of the LFRS and quantifies the impact of these selections on seismic performance and quality. The systems considered are: Rigid Frame, Core and Shear Wall and Tube in Tube. Moreover, applying value engineering approach on the solutions by considering two parameters: the design optimality index and design quality index. The design phase is considered one of the most important phases in the life cycle of a project. The coordination between designer and construction team should be insured to increase the building quality. So, improving the design phase by considering design quality to remain the project performance as well as time and cost saving. In this study, linear dynamic analyses of ten, twenty and thirty-story RC structures, which are primarily designed according to UBC 97, are performed. The results of the numerical simulations of dynamic linear responses were presented. Also results of design quality index were indicated. The recommendations for chosen the optimum structural system were based on the structure performance, maximum story drift, maximum displacement, and design quality indicators.
