Size Effect of Shear Failure in Prestressed Concrete Beams
It is shown that the size effect predicted by dimensional analysis of fracture mechanics of failures due to progressive distributed microcracking agrees with the test data existing in the literature better than the presently used strength (ultimate load) criterion, which exhibits no size effect, and better than the linear i!lastic fracture mechanics criterion, which exhibits much too strong a s...
متن کاملNonlinear Damping Identification in Precast Prestressed Reinforced Concrete Beams
This article presents a damage detection method for prestressed reinforced concrete (PRC) elements based on free vibration tests and nonlinear damping identification. Integrated static and dynamic experiments were carried out on three precast PRC beam specimens. The static loading induced different levels of damage to the beams. At each damage level, impulsive loading was applied to the beams a...
متن کاملHysteretic Behavior of Conventionally Reinforced Concrete Coupling Beams in Reinforced Concrete Coupled Shear Wall
This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...
متن کاملReliability evaluation of reinforced concrete beams
The purpose of this paper is to evaluate the time-invariant reliability of reinforced concrete beams designed under the provisions of the ACI Building Code. A wide range of practical design situations is considered. The beams are subjected to bending, shear, and torsion. The interaction between shear and torsion is considered via an elliptical failure surface defined in the shear-torsion stress...
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 ...
