Microcomputer‐Based Optimization of Steel Structures in Professional Practice

The paper concerns the computer-automated design of least-weight structural steel frameworks, where members are automatically sized using commercial standard steel sections in full conformance with steel design code provisions for strength/stability and stiffness. The necessary features and functions of such a design system are first identified. Two alternative approaches to the optimal design of steel frameworks are then discussed. Finally, a microcomputer software system is applied for the least-weight design of a steel framework comprised of a variety of member types and subject to a number of load effects. A number of alternative designs of the framework are conducted to illustrate differing optimization strategies and corresponding outcomes.
