| چکیده | ||
| Earth retaining structures are referred to those structures which can control backfill heights that are just about to slide. Some examples of these structures are gravity and cantilever retaining walls. The cantilever retaining walls were utilized after the introduction of the reinforced-concrete construction technique. In the previous studies, the optimization of the retaining walls has been accomplished by quasi-static methods; however, in this paper a pseudodynamic approach is utilized. The advantage of the pseudo-dynamic analysis is that the phase difference effects and time can be entered in the design of retaining walls as the dynamic characteristics of the earthquake loading. Here, by optimizing a cantilever retaining wall via a recently developed method, so-called Ray Optimization, the design controlling parameters are investigated. Ray Optimization method is a multi-agent optimization method which is inspired from the concept of light refraction. In this method by moving the agents to new positions, the optimal solution is found. | ||
