ABSTRACT
The Virtual Work Optimization Method (VWOM) is used in this paper to optimize steel structures for cost. The VWOM is an automated method that minimizes the cost of a structure with a given geometry, deflection criteria and load cases, while adhering to design code requirements. Members are selected from a user-defined database to meet design constraints which includes stiffness and strength criteria. The effect of labor and material costs on the optimized results are investigated. Two case are presented: (i) a two bay portal frame and (ii) a two bay three story building. A comparison of the optimized result with different mass/material and labor prices are compared.
