Effect of fiber amount and stirrup ratio on shear resistance of steel fiber reinforced concrete deep beams

نویسندگان

چکیده

This paper deals with the effect of steel fiber amounts and interaction between amount stirrup ratio on shear behavior capacity reinforced concrete (RC) deep beams fibers. The experimental program was carried out twelve different (0, 30, 40, 65 kg/m3) ratios (0.1, 0.15, 0.25%). test results have shown that use fibers increased resistance (up to 55%), reduced crack width 11 times) deflection 57%) tested beams. Also, it found using unsuitable would reduce efficiency in a beam due stirrups. Increasing high can efficacy enhancing beam. most cost-effective be around 30 45 kg/m3.
 Keywords:
 fibers; beam; capacity; amount; ratio.

Stepwise Regression for shear capacity assessment of steel fiber reinforced concrete beams

The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...

INFLUENCE OF FIBER ASPECT RATIO ON SHEAR CAPACITY OF DEEP BEAMS USING ARTIFICIAL NEURAL NETWORK TECHNIQUE

This paper deals with the effect of fiber aspect ratio of steel fibers on shear strength of steel fiber reinforced concrete deep beams loaded with shear span to depth ratio less than two using the artificial neural network technique. The network model predicts reasonably good results when compared with the equation proposed by previous researchers. The parametric study invol...

Retrofitting of Reinforced Concrete Beams with Steel Fiber Reinforced Composite Jackets

In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...

Shear Behavior Models of Steel Fiber Reinforced Concrete Beams Modifying Softened Truss Model Approaches

Recognizing that steel fibers can supplement the brittle tensile characteristics of concrete, many studies have been conducted on the shear performance of steel fiber reinforced concrete (SFRC) members. However, previous studies were mostly focused on the shear strength and proposed empirical shear strength equations based on their experimental results. Thus, this study attempts to estimate the...

Some Studies on Steel Fiber Reinforced Concrete

Fibres are generally used as resistance of cracking and strengthening of concrete. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural strength of concrete. According to various research papers, it has been found that steel fibres give the maximum strength in comparison to glass and polypropylene fibres. Hence, in this pr...
