Publication Description | Construction of steel structures involves different aspect ranges from material and connection to labor. As such, design of these structures should be based on cost rather than weight minimization. A review of papers on cost optimization of steel structures published in archival journals is presented in this paper. These structures include beams, slabs, columns, frames and bridges. Interesting and important results and conclusions are summarized. A review of reliability-based cost optimization is also included in this paper. It is concluded that there is a need to perform research on cost optimization of realistic three-dimensional structures, especially large structures with large number of members where optimization can result in substantial savings. On the other hand, actual and non simple design equations and constraints are to be included in the optimization procedure. |
