OPTIMAL DESIGN OF TRUSS BRIDGES USING TEACHING-LEARNING-BASED OPTIMIZATION ALGORITHM

In this study, teaching-learning-based optimization (TLBO) algorithm is employed for the first time for optimization of real world truss bridges. The objective function considered is the weight of the structure subjected to design constraints including internal stress within bar elements and serviceability (deflection). Two examples demonstrate the effectiveness of TLBO algorithm in optimizatio...

Optimal Truss Design Using Ant Colony Optimization

The paper presents a methodology to arrive at optimal truss designs using Ant Colony Optimization (ACO) algorithms. Ant Colony Optimization is a population-based, artificial multi-agent, general-search technique for the solution of difficult combinatorial problems with its theoretical roots based on the behavior of real ant colonies and the collective trail-laying and trail-following of its mem...

Modified genetic algorithm for optimal design of truss structures

Truss systems are widely used in engineering practice, mainly due to the economy, simple manufacturing, transportation and storage. These systems form the framework of such constructions as bridges, towers, roof supporting structures, etc. Usually a truss system includes a large number of elements (trusses), which can have different parameters (length, cross-sectional area, shape of crosssectio...

An Introduction to Optimality Criteria and Some Results on Optimal Block Design

X ′Xθ = X ′Y. Here, X ′X is called the “information matrix” of θ and var(θ̂) = σ(X ′X)−1 (provided Rank(X) = t). Let l′θ be an estimable linear parametric function. Then var(l′θ̂) = σ2l′(X ′X)−l. We choose a design d, with design matrix Xd, whose information matrix X ′ dXd is “large” (equivalently, (X ′ dXd) − is “small”) in some sense. Now, suppose we are interested in a component θ1 of θ. We write

Optimality criteria method for optimal design in hyperbolic problems∗,†

We consider an optimal design problem with a hyperbolic initial boundary value problem as the state equation. As a possible application consider a body made from a mixture of different materials which is vibrating under the given external force, subject to a prescribed boundary and initial values. The control function (the distribution of given materials in the given domain) uniquely determines...
