Twelve self compacted concrete (SCC) T-section beams were design and tested to determine the effect of using SCC on the shear behavior under two concentrated loads. All beams have the same longitudinal steel ratio of (0.018823) and gross section area of (20000) mm 2. The tested beams were divided into two groups-with and without stirrups. The first...

The beam on elastic foundation is a common technical problem in engineering and many solutions have been proposed in recent years. The key aspect in the design of flexible structural elements in contact with bearing soils is the way in which soil reaction, referred to qualitatively as soil's reactive pressure (p), is assumed or accounted for in ana...
