Abstract

This study is devoted to investigating the structural behavior of reinforced concrete hollow beams filled with cellular concrete blocks (thermostone) under the effect of shear. The number (or location) of the thermostone blocks is the major variable adopted in this research, while, the other variables are kept constant for all tested specimens. The experimental part includes casting and testing of five (200x300x1200mm) beam specimens with different locations of internal thermostone blocks. The experimental results indicated that the shear strength is increased (from 33%) to (70%) for beams containing internal ribs in comparison with the reference beam. Also, the change of beam state from hollow section to solid section led to increasing the capacity by about (100%). Comparison with ACI-318 Code empirical equation for shear takes place and the results indicated that the ultimate loads are in good agreement with the experimental results.
