Abstract
The conventional ACI-ASCE design approach to shear developed for reinforced portland cement concrete does not yield very good results when applied to reinforced polymer concrete (PC). A new procedure that combines the techniques of dimensional analysis and statistical regression analysis is therefore recommended for steel-reinforced PC beams without web reinforcement. The PC beams were made using unsaturated polyester resins and were designed in such a way to achieve a wide range of values in the variables affecting the shear strength of reinforced PC. The new procedure gives excellent results for both short beams and long beams.
