On the Transverse Strength of Fiber-Reinforced Materials
Journal of Applied Mechanics, 1973Using plasticity limit theorems, transverse strengths for unidirectionally reinforced composites containing fibers with hexagonal cross sections are found and compared with earlier “exact” values found by Drucker for symmetric deformation. Using unsymmetric deformation modes, upper bounds are found which are lower than the values found by Drucker for ...

Transverse Flow of Fibre-Reinforced Composites
1990An experimental and theoretical investigation into the flow of continuous fibre-reinforced materials is presented. In particular a study is made of the flow mechanisms that take place during consolidation under constant load. A theoretical model is considered in which the material is treated as an incompressible anisotropic fluid.

Drift Capacity of Reinforced Concrete Columns with Light Transverse Reinforcement
Earthquake Spectra, 2005Existing reinforced concrete columns with light transverse reinforcement are vulnerable to shear failure during seismic response. Shear strength models, modeling the degradation of shear strength with increasing displacement ductility demand, have been widely used to evaluate the interstory drift capacity of such columns.

Shear Strength of Reinforced Concrete Beams without Transverse Reinforcement
ACI Structural Journal, 2001This paper presents a simplified analytical model to compute the shear strength of reinforced concrete members without stirrups. The approach uses basic principles of mechanics and a parametric study of experimental data. The main variables considered are: the compressive strength of concrete; longitudinal reinforcement ratio; and shear span-to ...

Post-earthquake examinations of reinforced concrete structures often show structural damage resulting from bond and shear failures. Such failures typically occur in reinforced concrete elements with details known to cause problems, such as widely spaced transverse reinforcement and/or lap splices located in regions of flexural yielding.

Abstract In this paper, the description of the shear strength of orthogonally reinforced concrete slabs without transverse reinforcement by the newly developed extended sandwich model is presented. Based on a sandwich model, the slab element is subdivided into two cover elements and a core element, respectively; while the covers are subjected to in ...

Shear design of FRP reinforced concrete beams without transverse reinforcement
Composites Part B: Engineering, 2014Abstract A simple and rational model for the prediction of the shear strength of FRP reinforced concrete beams without shear reinforcement is presented. The method is based on the principles of structural mechanics and on the experimentally observed behavior of RC beams at shear-flexural failure.

This study investigates the effects of transverse reinforcement ratios on the post-elastic performance of diagonally-reinforced coupling beams in coupled core wall systems. Two coupled wall subassemblages, with two different transverse reinforcement detailings, were designed and tested under cyclic reversed loads.

Can Steel Fibers Replace Transverse Reinforcements in Reinforced Concrete Beams?
ACI Materials Journal, 1997Steel fiber reinforced concretes currently used do not have enough post-cracking tensile strength to be used alone, without main reinforcement (rebars), in a beam. On the other hand, replacement of the secondary reinforcement (stirrups) seems promising.
