Each fall, our Reinforced Concrete Design Lab provides our civil engineering students hand’s on experiences in the design, construction and testing of concrete beams. This year the experience was captured and posted to YouTube by civil engineering senior Scott Jackson. Scott’s lab mate civil engineering senior Antonio Sanchez described the insights they obtained from the experience. “By going through the entire process from making the forms to pouring the concrete, we learned to appreciate the procedure that goes into making a designed beam become real. The testing also allowed us to experience what we’ve been looking at in our books with regards to the different types of cracks that may appear on the concrete beam throughout its service life and analyze the causes of why they appear. It is a very useful experience to have when contrasted to the constant classroom environment.”
Scott shot the video to show it “to others who post SolidWorks and CAD designing projects online” and to capture and share with classmates, family and friends the work he and his classmates have done on projects like this one. Featured in the video is CE422 Reinforced Concrete Design Professor Ganesh Thiagarajan, GTA Gunjan Shetye and civil engineering students Scott Jackson, Antonio Sanchez and Brandon Sisk as the class is divided into 5-6 small groups with each laboratory group responsible for the construction of one of the several beams that will be tested. The student projects are designed to give students insight into the fundamental concepts and effects of reinforcement in concrete flexural members, specifically 1) flexural behavior in terms of reinforcement ratios and its effect on ductility and 2) shear behavior and the role of shear reinforcement (stirrups). The beam shown in the video was one of three different types constructed by the class with each type differing in the amount of steel that was placed to resist the tension forces when pressure loads were applied. Deflection was measured and calculations were based on 150 lbs/cf. We think it’s safe to say, “Beam us up, Engineer Scott”.
