The content in the link of Post #1 is too short thus it appears to be the abstract of the paper.
I could not find the full paper but instead I found a related paper by the same authors.



Reinforced concrete beams without stirrups considering shear friction and fracture mechanics
Kazemi, M.T.1 ; Broujerdian, V.1

Abstract:

A new expression for the shear capacity of reinforced concrete beams without stirrups was derived by calculating the aggregate interlock capacity across the major diagonal crack of the beam, a procedure somewhat similar to those based on the modified compression field theory. Two formulas were obtained from the simplification of this expression. All three relations capture the dependence of shear strength on the size of the beam, the ratio of shear span to beam depth, longitudinal reinforcement ratio, maximum aggregate size, and concrete strength. The limits of these formulas agree well with the limit solutions of shear failure load for very small and very large beams based on plastic and fracture mechanics solutions, respectively. The proposed relations were calibrated by least-squares fitting of the existing experimental database (consisting of 398 data points) and resulted in low coefficients of variation. The simplest version is suitable for design codes. © 2006 NRC Canada.(20 refs)
