Structural Optimization for Seismic Design
The application of Heuristic Search Methods for the earthquake resistant design of structural frames is discussed. The Tabu Search method was selected for application to structural weight optimization of steel moment frame structures. A computer program was developed that uses Tabu Search for weight minimization of two-dimensional framed structures. Written in the FORTRAN computer language, the...
متن کاملOptimization and Multihazard Structural Design
There is a growing interest in the development of procedures for the design of structures exposed to multiple hazards. The goal is to achieve safer and/or more economical designs than would be the case if the structures were analyzed independently for each hazard and an envelope of the demands induced by each of the hazards were used for member sizing. We describe an optimization approach to mu...
متن کاملMultimodal structural optimization for conceptual design
The paper describes an optimization method to support the conceptual stages of structural design. The method, called Blended Close Harmony Search, is a population-based metaheuristic approach that incorporates the following key features: 1) decision variable types that include real numbers defining geometry, discrete structural sections, and topology variables of enumeration (e.g. how many bays...
متن کاملSolid Free Form Design for Structural Optimization
Most of the work in the field of topology optimization is concentrated on using sensitivity analysis and optimality criteria methods that need explicit formulation. The design systems are often hard-coded for a specific problem with specialized optimization and FEM routines. This paper presents a work that uses a system approach to solid free form design. It attempts to develop a general topolo...
متن کاملStructural Design Optimization using Generalized Fuzzy number
This paper presents solution technique of geometric programming with fuzzy parameters to solve structural model. Here we are considered all fuzzy parameters as a generalized fuzzy number i.e. generalized triangular fuzzy number and generalized trapezoidal fuzzy number. Here material density of the bar, permissible stress of each bar and applied load are fuzzy numbers. We use geometric programmi...
