چکیده

Fatigue cracks often occur in the deck asphalt pavement of steel bridges at top longitudinal stiffening rib. To prevent this issue, traditional design strategy bridge structure was optimized, and a new approach is presented. This optimization technique exploits strength simulation steel—epoxy structure, stress concentration location subsequently determined. A solid model including sensitive areas then established. We examined maximum point layer stiffeners variation stiffeners. reduce stiffeners, an method that combines orthogonal experimental design, neural network (BP), genetic algorithm (GA) for GA—BP utilized to optimize Sutong Yangzi River Bridge. confirmed presented improved fatigue reliability established efficacy method.

Parameters Optimization for Piezoelectric Harvesting Energy from Pavement Based on Taguchi’s Orthogonal Experiment Design

To effectively harvest vibration energy from pavement without affecting driving comfort and safety, parameter optimization was done with the orthogonal experiment design and the finite element analysis. L16(44) Taguchi’s orthogonal experiments were carried out with planted depth, PZT material, PZT diameter and thickness as optimization parameters and with open voltage and pavement displacement ...

An orthogonal design based constrained evolutionary optimization algorithm

Solving constrained optimization problems (COPs) via evolutionary algorithms (EAs) has attracted much attention. In this article, an orthogonal design based constrained optimization evolutionary algorithm (ODCOEA) to tackle COPs is proposed. In principle, ODCOEA belongs to a class of steady state evolutionary algorithms. In the evolutionary process, several individuals are chosen from the popul...
