The main goal of the structural optimization is to minimize the weight of structures while satisfying all design requirements imposed by design codes. A truss design model in fuzzy environment has been developed. The present paper proposes a fuzzy geometric programming approach in parametric form .We have considered a single objective structural optimization problem with weight as an objective function. The structural related load and other parameters are taken as fuzzy in nature. This structural model is formulated as a fuzzy geometric programming problem in parametric form. Fuzzy geometric programming in parametric approach is used to solve this single objective structural optimization model. Numerical example is given to illustrate the model through this approximation method. This approach provides an alternative solution technique to this problem. This method is more reliable and acceptable.

Truss design optimization using fuzzy geometric programming in parametric form

A method for minimization of the square sum of the natural periods of vibration of a frame

The main objective of structural engineers through out design history has been to obtain structure under the prescribed design conditions which can not only withstand external loads safety but also achieve an economic solution. This paper we apply General Fuzzy Non-Linear Programming [GFNLP] technique as well as Intuitionistic Fuzzy optimization[IFO] technique to solve the problem of optimum design of plane truss structures. Our objective is to prove IFO method perform better than GFNLP method. This approach is illustrated on planer truss optimization model and the results are discussed.

Fuzzy optimum design of plane truss structures

The main objective of structural engineers throughout design history has been to obtain structure under the prescribed design conditions which can not only withstand external loads safety but also achieve an economic solution. This paper focuses on the use of geometric programming solution method to optimum design of plane truss structures. This approach is illustrated on planer truss optimization model and the results are discussed.
