Performance Evaluation of One-Way Concrete Slabs Reinforced with New Developed GFRP Bars

MOUTH BROODING FISH ALGORITHM FOR COST OPTIMIZATION OF REINFORCED CONCRETE ONE-WAY RIBBED SLABS

In this paper, the optimum design of a reinforced concrete one-way ribbed slab, is presented via recently developed metaheuristic algorithm, namely, the Mouth Brooding Fish (MBF). Meta-heuristics based on evolutionary computation and swarm intelligence are outstanding examples of nature-inspired solution techniques. The MBF algorithm simulates the symbiotic interaction strategies adopted by org...

OPTIMAL DESIGN OF REINFORCED CONCRETE ONE-WAY RIBBED SLABS USING IMPROVED TIME EVOLUTIONARY OPTIMIZATION

In this paper, a new robust metaheuristic optimization algorithm called improved time evolutionary optimization (ITEO) is applied to design reinforced concrete one-way ribbed slabs. Geometric and strength characteristics of concrete slabs are considered as design variables. The optimal design is such that in addition to achieving the minimum cost, all design constraints are satisfied under Amer...

Experimental Strengthening of the Two-way Reinforced Concrete Slabs with High Performance Fiber Reinforced Cement Composites Prefabricated Sheets

Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases strengthening of structural elements is much more economical than rebuilding the structure. Using HPFRCC with tensile stiffening behavior has been developed to strengthen the concrete structures over the recent few years. In this paper,...

Heat Transfer Analysis of Reinforced Concrete Beams Reinforced with GFRP Bars

Investigation of structural behaviour of GFRP reinforced concrete deck slabs through NLFEA

This paper presents a numerical study of the structural behaviour of concrete bridge deck slabs under static patch loads and dynamic traffic loads and an investigation of compressive membrane action (CMA) inside slabs. Those deck slabs were reinforced with Glass Fibre Reinforced Polymer (GFRP) bars. Non-linear finite element analysis (NLFEA) models were established using ABAQUS 6.10 software pa...
