Plastic Layout Optimization of Large-Scale Frameworks Subject to Multiple Load Cases, Member Self-Weight and with Joint Length Penalties
1. Abstract In the past few decades plastic layout optimization methods have been largely ignored in favour of those based upon elastic design principles. However, when multiple load cases are present elastic methods are generally computationally expensive and/or are prone to finding local optima. Therefore, they may not at present provide a suitable basis for practical truss layout optimizatio...
متن کاملimproved seismic design of structural frames by optimization of equivalent lateral load pattern
well-known seismic design codes have offered an alternative equivalent static procedure for practical purposes instead of verifying design trials with complicated step-y-step dynamic analyses. such a pattern of base-shear distribution over the building height will enforce its special stiffness and strength distribution which is not necessarily best suited for seismic design. the present study, ...
متن کاملExperimental Load Transfer of Piles Subject to Lateral Soil Movement
Remediation of slope failures requires stabilization alternatives that address causes of slope instability. Slope reinforcement and pile stabilization systems, if properly designed, are effective in preventing slope movements in weak soils. Soil load transfer to pile elements from the lateral soil movement as occurs in slope failures is a complex soil-structure interaction problem, and the sign...
متن کاملTopological Derivative-based Topology Optimization of Structures Subject to Multiple Load-cases
The topological derivative measures the sensitivity of a shape functional with respect to an infinitesimal singular domain perturbation, such as the insertion of holes, inclusions or source-terms. The topological derivative has been successfully applied in obtaining the optimal topology for a large class of physics and engineering problems. In this paper the topological derivative is applied in...
متن کاملLayout Optimization of Braced Frames Using Differential Evolution Algorithm and Dolphin Echolocation Optimization
In this study, topology optimization is applied to concentrically braced frames in order to find economical solutions for conventional structural steel frames. Differential Evolution Algorithm and Dolphin Echolocation Optimization are applied for structural optimization. Numerical examples are studied and results of comparison with other meta-heuristic algorithms, including Genetic Algorithm, A...
