1. Abstract The distributed Genetic Algorithm (GA) for PC cluster with multi-core-CPUs is proposed as a time reducing method for determining the schemes of retrofitting existing buildings with Buckling restrained Brace (BRB). Nondominated Sorting Genetic Algorithm-II (NSGA-II), one of the derivative evolutionary algorithm in heuristic method, was applied since the optimization problem have a mu...

fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced concrete beam-column connections. Developing strut-and-tie models in reinforced concrete beam-column connections is treated as a topology optimizatio...

The static behavior of reinforced concrete (RC) beams plated with layers of fiber-reinforced composite material (FRP) is widely investigated in current literature, which deals with both its numerical modeling as well as experiments. Scientific interest in this topic is explained by the increasing widespread use of composite materials in retrofitting techniques, as well as the consolidation and ...

In this paper, a nonlinear finite element (FE) analysis of hybrid-steel concrete connections is presented. The detailed experimental results of the four full-scale hybrid-steel concrete connections with limited seismic detailing have been discussed in a different paper. However, due to the inherent complexity of beam–column joints and the unique features of the tested specimens, the experimenta...

lateral resistance of railway track is one of the most important parameters in lateral stability. this parameterdepends!on the conditions of different components of ballasted railway track (such as density of ballast layer,sleeper spacing, type of sleeper, etc.). from this perspective, type of sleeper has an important effect on lateralresistance. however in some conditions, in technical and eco...

Traditionally, reinforced concrete (RC) walls have long been adopted as an efficient lateral load resisting systems to enhance the stability and integrity of the buildings against dynamic actions such as wind, earthquakes etc. Later, steel plate walls were proposed as a promising alternative of concrete walls. Thin steel plate walls contributed in weight reduction of the structure with greater ...
