Shear capacity of concrete slabs reinforced with glass
The ultimate shear capacity of slabs reinforced with glass-fiber-reinforced polymer (GFRP) bars is compared with the shear strength predicted using the modified compression field theory (MCFT). This paper uses the results of 20 tests of GFRP-reinforced slabs with either lightweight or normalweight concrete with measured strengths in excess of
5 Methods for On-Site Evaluation of Concrete Strength
On-site evaluation of concrete strength is a challenge in the assessment of existing structures. Combination of NDT methods can be used to measure strength.
PDF Out-of-Plane Shear Strength of Reinforced Concrete Walls
2006) has shown that deep, lightly reinforced one-way slabs, particularly if constructed with high-strength concrete or concrete having a small coarse aggregate size, may fail at shears less than Vc calculated from Eq. (126.96.36.199). One-way slabs subjected to concentrated loads are more likely to exhibit this vulnerability.

PDF Composite Slabs and Beams using Steel Decking: Best
Composite slabs consist of profiled steel decking with an in-situ reinforced concrete topping. The decking not only acts as permanent formwork to the concrete, but also provides sufficient shear bond with the concrete so that, when the concrete has gained strength, the two materials act together compositely.
Punching Shear CSCT - Punching Shear in Reinforced
Punching shear strength of reinforced concrete slabs without transverse reinforcement." ACI structural Journal, 4 ( ): 440-450. The app currently covers the theoretical case of an axisymmetric circular slab. The user can specify the geometry and reinforcement of the slab.
PDF Design of Reinforced Concrete Beams per ACI 318-02
A) Flexural Strength of Reinforced Concrete Beams and Slabs 1. Introduction The design of reinforced concrete structural members may be done by two different methods. One, called working stress design (WSD), is based on the straight-line distribution of compressive stress in the concrete (Fig. 1), covered in Appendix B by ACI 318.
Ultimate Flexural Capacity of Reinforced Concrete Elements
Worldwide, steel corrosion is one of the greatest deterioration problems for reinforced concrete structures. Comparing some experimental results from literature with a complex FEM model, the present paper points out the principal aspects that characterize the static behavior of reinforced concrete (RC) elements damaged by corrosion. Moreover, the nondimensional abaci defined for some specific
Flexural Strengthening of Concrete Slab-Type Elements with
The ultimate load-carrying capacity of the strengthened slabs was compared with that of an unstrengthened slab as well as the theoretical solutions. The failure test results indicated that the stiffness and the ultimate flexural capacity of the strengthened slab were at least 112% and 165% greater, respectively, than that of the unstrengthened
