Alternative Formulations for Structural Optimization: An Evaluation Using Frames
Publisher: American Society of Civil Engineers
Abstract: Two alternative formulations based on the concept of simultaneous analysis and design are presented and evaluated for optimal design of framed structures. Different behavior variables, such as nodal displacements and member ...
Standardization of Steel Pole Design Using Discrete Optimization
Publisher: American Society of Civil Engineers
Abstract: An optimal design formulation is presented that incorporates the use of standard prefabricated sections for the design of steel transmission poles. This standardization is achieved by discretizing the design variables for ...
Optimal Design of Latticed Towers Subjected to Earthquake Loading
Publisher: American Society of Civil Engineers
Abstract: The problem of optimal design of latticed transmission towers subjected to normal operating loads and an earthquake load is formulated. A time history analysis of the structure is performed. The constraints given in a ...
