finite element analysis of steel fiberreinforced concrete

This has resulted in an increased volume of high quality fly ash that is considered a waste product or a by-product that can be utilized in products such as portland cement concrete. There are several sources of the high quality fly ash located in Iowa currently producing a combined total of 281,000 tons of material annually.

In this paper, several FRP-reinforced concrete beams are modelled using a recently developed one-dimensional two-node layered composite beam element which accounts for the bond-slip between reinforcing bars and the surrounding concrete. Effect of different surfaces of FRP reinforcing bars on the structural response of FRP-reinforced concrete beams with bond-slip effect is also investigated.

This paper utilizes the advanced potential of pseudodynamic three-dimensional finite-element modeling to study the axial mechanical behavior of square and rectangular reinforced concrete columns, confined with fiber reinforced polymer (FRP) jackets and continuous composite ropes in seismic applications.

ABSTRACT Finite element models are analyzed and validated with the experimental shear capacities of steel fiber reinforced concrete (SFRC) as well as plain concretes. In this work, steel fibers with low aspect ratio which are commonly available in Bangladesh are used and sufficient capacity enhancements are attained.

The replacement of ordinary steel reinforcement by steel fibres can represent a great advance in this industry. The use of discrete steel fibres as a reinforcement system for cement based materials is now a current practice for several applications (di Prisco et al. 2004). The resulting material is designated Steel Fibre Reinforced Concrete (SFRC).

A new approach for nonlinear finite element analysis of corroded reinforcements in reinforced concrete (RC) structures is elaborated in the article. An algorithmic procedure for producing the tension-stiffening curve of RC elements taking into consideration most of effective parameters, e.g.: the rate of steel bar corrosion, bond-slip behavior

This thesis investigates the shear capacities of carbon-fiber reinforced polymer (CFRP) prestressed concrete T-beams using a non-linear finite element analysis. The finite element models on ANSYS are validated with the experimental results of four beams having the shear

Oct 15,  · A series of portland cement concrete mixtures covering (i) the selected coarse RAPs with varying replacement levels, (ii) 0.40 w/cm ratio and (iii) 309 kg/m 3 (520 lb/cy) cementitious content (20% fly ash replacement) were formulated. The amount of air entraining agent was selected to produce air content of 5.0% in the mixtures.

the concrete and steel reinforcement is assumed in the finite element analysis, but the assumption would not be true for the experimental beams. As bond slip occurs, the composite action between concrete and steel reinforcing bar is lost. Therefore, the overall stiffness of
