Comparison Of Measured And Calculated Stiffnesses For Lightweight Normal Concrete Beams, Raman Patel

Masters Theses

"This study is a presentation of the findings involving experimental measurements of stiffness (EI) for different percentages of reinforcement steel in normal and lightweight concrete beams. The experimental values of stiffness are compared with calculated values obtained by applying the standard reinforced concrete theory. The measured values of stiffness obtained by the rotation method are compared with those obtained by the deflection method. Of the thirty beams that were tested, fifteen were tested for normal concrete and the remaining fifteen for lightweight concrete. Each of these beams were tested at different ages, ranging from seven to twenty-eight days.

The test …
