چکیده
The research efforts reported here are aimed at experimentally investigating the effects of incorporating steel fibres, with various dosages, on shear capacity and behaviour characteristics reinforced concrete deep beams. primary experimental results obtained during this research, as well an extensive secondary dataset, were used to examine verify a proposed new model by authors for calculating resistance fibres (SFRC) investigation involved 12 beams four namely: 0, 30, 40, 65 kg/m3 three stirrup ratios, 0.1%, 0.15%, 0.25%. have shown that improved (up 55%), decreased crack width 68%), reduced displacement 57%), enhanced deformation 45%). propose semi-empirical formula estimation SFRC accuracy was evaluated using 116 dataset including project published dataset. reliability compared other formulas. It is evident newly increases when previously models.

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...
متن کاملDevelopment of Shear Capacity Equations for Rectangular Reinforced Concrete Beams
The problem of shear is not yet fully understood due to involvement of number of parameters. Designers are extra careful about shear, especially in beams and consequently higher safety factors are used in shear design. Several equations are available in literature to determine the shear capacity of beams, i.e. ACI equation, Zsutty equation and KIM & White equation. To verify the application of ...
متن کاملA Simple Approach to Predict the Shear Capacity and Failure Mode of Fix-ended Reinforced Concrete Deep Beams based on Experimental Study
Reinforced Concrete (RC) deep beams are commonly used in structural design to transfer vertical loads when there is a vertical discontinuity in the load path. Due to their deep geometry, the force distribution within the RC deep beams is very different than the RC shallow beams. There are some strut and tie model (STM) already been developed for RC deep beams. However, most of these models are ...
متن کاملExperimental Investigation on Shear Cracking Behavior in Reinforced Concrete Beams with Shear Reinforcement
This paper presents an experimental investigation to clarify shear cracking behavior of reinforced concrete beams. The effects of the various influential parameters on the spacing between shear cracks and the relationship between shear crack width and stirrup strain at the intersection with shear cracks were carefully investigated. It was found that shear crack width proportionally increases wi...
