چکیده
The objective of this article is to present an optimization problem formulation reduce the total structural cost prestressed doubly-symmetric and monosymmetric I-shaped steel simply supported beams with straight tendons. was implemented via MATLAB’s native Genetic Algorithm. validation evaluation processes adopted two examples from literature. design method follows Brazilian standard NBR 8800:2008 for Ultimate Serviceability Limit States. best result found a case by up 20.00% 25.70%. Saving in material weight installation tendons, without exceeding security limits, also effective. Furthermore, results presented efficient alternative engineering, providing significant model similar analyzes.

Computational cost of metaheuristic based optimum design algorithms grows excessively with structure size. This results in computational inefficiency of modern metaheuristic algorithms in tackling optimum design problems of large scale structural systems. This paper attempts to provide a computationally efficient optimization tool for optimum design of large scale steel frame structures to AISC...
متن کاملPrediction of effective moment of inertia for hybrid FRP-steel reinforced concrete beams using the genetic algorithm
Abstract: The use of Concrete beams reinforced with a combination of fiber reinforced polymer (FRP) and steel bars has increased dramatically in recent years, due to improvement in strength and flexural ductility simultaneously. In this paper, we proposed a new equation for estimating the effective moment of inertia of hybrid FRP-steel reinforced concrete (RC) beams on the basis of the...
