Three forms of lateral systems i.e. moment frames, steel cross bracings and concrete shear walls are utilized at varying elevations of the building to determine an optimal set of results. Besides analyzing structural optimality, the MATLAB algorithm developed as a part of this research paper also evaluates each system for its overall structural weight, material cost and embodied carbon. By taking a multi-objective optimization approach at the design of lateral load-resisting systems in buildings, this research devises a practical tool that can be used by designers to assess and examine the advantages and disadvantages of various layouts of lateral systems. The algorithm also enables the user to specify the location and type of certain lateral elements, which may correspond to practical architectural constraints, and juxtapose results from user-defined layouts with the optimized solution.","abstract_html":"This thesis explores the advantages of using vertically mixed lateral systems in rectangular buildings consisting of uniform bay dimensions.
