Abstract

"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 results indicate that the measured values of stiffness decrease with an increase in the bending moment. For noncracked sections the measured values are higher than the calculated values. Best agreement between the theoretical and measured values of EI occurred shortly after the cracked section was formed. The best correlation between the rotation and deflection method for determining stiffness also occurred in this same region"--Abstract, page ii.
