Evaluation of Shear Design Provisions for Reinforced Concrete Beams and Prestressed Concrete Beams
Journal of the Korea Concrete Institute, 2005Shear 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.

Water distribution in concrete beams
Materials and Structures, 2004Moisture transfers have a major effect on concrete durability. For Alkali-Silica Reaction (ASR), chemical swellings depend on water content, and drying can have important consequences. Within the framework of a large experimental study developed in partnership by the Laboratoire Central des Ponts et Chaussees (LCPC) and Electricite de France (EDF), the

Analysis of Concrete Masonry Beams
Journal of Structural Engineering, 1995This paper presents an in-depth structural engineering and structural reliability analysis of concrete masonry beams. The ductile response of masonry beams was studied in detail. A limit-state design methodology for reinforced-concrete masonry beams is presented in this paper based on the principles of structural reliability.

A LIMIT MODEL IN THE ANALYSIS OF STEEL-CONCRETE BEAMS
Mathematical Models and Methods in Applied Sciences, 2000The problem of two bodies joined along their common surface by a thin soft third material having a periodic micro-structure has been considered. After identifying the two natural smallness parameters ε (which measures the thickness and the softness of the intermediate body) and η (which is the period of the micro-structure), the limits of the solution ...

Although the geometry of the influence of the load on a beam is identical irrespective of material there is a fundamental difference in the way that a reinforced concrete beam produces the resistance moment. Within very small limits, a plain concrete beam would behave like any other elastic material.

Beams — Concrete and Plasterboard
1990Once having produced a level ceiling, the work of squaring up a beam is made much easier. If the beams are deep, it may be an advantage to work in the sides or cheeks of the beam from the ceiling scaffold, and the bottom or soffit from a scaffold set up at a lower level.

Concrete Beams with Prestressed Reinforcement
Journal of the Structural Division, 1970Tests on six rectangular beams reinforced with variable amounts of deformed steel bars and precast prestressed concrete prisms are reported. Methods are suggested for computing the moment causing cracking of the in situ concrete and that causing cracking of the prestressed reinforcement.

Prestressed concrete simple beams
1987Prestressed concrete construction has now developed [1–4] to such a stage that a general understanding of its principles and of the design procedures is necessary for the structural engineer. Prestressed concrete may be defined as concrete in which internal stresses of such magnitude and distribution have been introduced that the stresses resulting ...

Performance of Concrete Masonry Beams
The Masonry Society Journal, 1993This research studied the performance of concrete masonry beams. The neutral axis location and the ductility capacity of beams was quantified as a function of bar size. A limit state characterization of performance is proposed.

DEFLEXIONS OF REINFORCED CONCRETE BEAMS
Proceedings of the Institution of Civil Engineers, 1972A SERIES OF SUSTAINED LOADING TESTS ON REINFORCED CONCRETE BEAMS IS DESCRIBED, IN WHICH THE MAJOR FACTORS AFFECTING THE DEVELOPMENT OF DEFLEXION AND CRACKING WERE VARIED. THE RESULTS OF THE TESTS ARE DISCUSSED AND METHODS FOR ESTIMATING DEFLEXION OF REINFORCED CONCRETE BEAMS ARE PROPOSED. /AUTHOR/
