Cellular Automata Approach in Optimum Shape of Concrete Arches under Dynamic Loads

Traditional methods in determination of optimum shape of structures don’t scale well. This paper discusses the application of cellular automata (CA) to study of optimum shape in concrete arches under dynamic loads by cellular automata and presents a novel approach for that. In this paper, samples of semi-circular, obtuse angel, four- centered pointed, Tudor, ogee, equilateral, catenaries, lancet and four-centered arches are modeled. Then they are analyzed and optimized under acceleration–time components of Elcentro earthquake. Using cellular automata model and provided rules, the mentioned arches are analyzed and optimized. The results of error range and time of analysis in cellular automata model and FEM software compared. According the results, in CA method, precision is less but it has less time of analysis and optimization .
