The application of LRFD specification initiated numerous research works in this field. Beams with an extreme fiber tensile stress greater than 4. Due to this small strain capacity of plain concrete, only a small amount of longitudinal reinforcement could be used in order to ensure that the flexural member is tension-controlled. 00 Non-Member Price: $440. The geometrical proportion of beam sections are noted. In order to prevent slip between the two beams at the interface and ensure bending strain compatibility shear connectors are frequently used. The article explains right from the basics of load distribution over beams and moves into the core of the subject as it finally unfolds all the expressions required for the calculations of beam loads. A rail height of 28 inches is desirable to accommodate future overlays. Number of Girders/Spacing.
