Abstract:
To enable structural designers to make more accurate assessments of the long-term deflection performance of reinforced concrete flat slabs and plates, the deflections of several actual slabs were measured for up to 9 years, and the results were compared with calculated values. It was found that the measured values were up to five times the values calculated by normal methods. A more accurate method of calculation was developed. This paper provides additional research information for one previous investigation, and summarizes others for the purposes of comparison.
