Cracking and Crushing in Prestressed Concrete Beams

ACI Structural Journal, 2021
The cohesive/overlapping crack model represents an effective tool in the study of failure transition phenomena occurring in plain or reinforced concrete structures. In the present paper, this non-linear fracture mechanics model is applied to study the global structural behavior of prestressed concrete beams casted by means of pre-tensioning technique ...

Design of reinforced concrete beams

1996
Reinforced concrete beam design consists primarily of producing member details which will adequately resist the ultimate bending moments, shear forces and torsional moments. At the same time serviceability requirements must be considered to ensure that the member will behave satisfactorily under working loads.

Evaluation of Shear Design Provisions for Reinforced Concrete Beams and Prestressed Concrete Beams

Journal of the Korea Concrete Institute, 2005
Shear test data have been extracted from previous experimental research and compiled into a database that may be the largest ever made. In this paper, the shear database (SDB) was used for evaluating shear design provisions for both reinforced concrete (RC) beams and prestressd concrete (PSC) beams.

Damage modelling of reinforced concrete beams

Advances in Engineering Software, 2007
Analysis of reinforced concrete building floor frames can be significantly improved when appropriate material models are assumed to represent the actual global behaviour and consequently to improve the ultimate and serviceability limit state verifications.

Vibrations of Steel-Concrete Composite Beams

Journal of Vibration and Control, 2000
This paper is an experimental analytical investigation on the dynamic behavior of steel-concrete composite beams subject to small vibrations. A one-dimensional model of a composite beam is presented, where the elements connecting the steel beam and the reinforced concrete slab are described by means of a strain energy density function defined ...

Flexural Deformability of Reinforced Concrete Beams

Journal of Structural Engineering, 1998
In reinforced concrete beams, the sectional definition of the moment-curvature relationship is not straightforward owing to the presence of cracks. In general, this problem has been solved by considering a representative portion of the beam and by defining the curvature 1/\ir as the ratio between the rotation of the portion considered and its length ...
