ABSTRACT
The Virtual Work Optimization Method(VWOM) is used in this paper to optimize steel structures and connections. 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 including stiffness and strength criteria. Connections are designed using the eToolkit. The cost is calculated using a costing sheet, which accounts for labor and material cost. The contribution of connection cost to the overall structural cost is explored. Three case studies are considered (i) one bay portal frame; (ii) one bay two story building; (iii) four story one bay building.
