Strengthening of Existing RC Two-Way Slabs using New Combined FRP fabric/rod Technique
This study presents the results of an experimental program to investigate the effectiveness of an innovative combined FRP technique using combination of externally bonded (EB) FRP fabrics and near surface mounted (NSM) FRP rods for flexural strengthening of existing reinforced concrete (RC) two-wayslabs with low clear cover thickness. Three full-scale RC slabs (1500×1500×120 mm) were tested und...
متن کاملExperimental 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,...

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...
متن کاملShear Strengthening Using Cfrp Sheets for a Prestressed Concrete Highway Bridge in Manitoba, Canada
The use of heavier trucks demanded upgrading of a twenty-seven year old bridge in Winnipeg, Manitoba, Canada. Analysis of the precast prestressed concrete girders using the current AASHTO Code indicates a deficiency in the shear capacity. Shear strengthening using Carbon Fibre Reinforced Polymer (CFRP) sheets provides a low-cost solution by increasing the speed of construction and reducing traf...
