Experimental investigation to compare the modulus of rupture in high strength self compacting concrete deep beams and high strength concrete normal beams
This paper investigates and compares the cracking moment and modulus of rupture in deep and normal beams. Eight high-strength-self-compacting concrete (HSSCC) deep beams and nine high-strength concrete (HSC) normal beams are casted and tested. The results from ACI 318-95 and CSA-94 codes show the di...

| Summary: | This paper investigates and compares the cracking moment and modulus of rupture in deep and normal beams. Eight high-strength-self-compacting concrete (HSSCC) deep beams and nine high-strength concrete (HSC) normal beams are casted and tested. The results from ACI 318-95 and CSA-94 codes show the discrepancies in values of modulus of rupture for HSSCC deep and normal beams. These differences are due to non-consideration of load transfer mechanism in deep beams and high strength of concrete. Based on the present study ACI 318-95 is recommended for calculating modulus-of-rupture in HSSCC deep beams whereas CSA-94 is suggested for HSC normal beams. |
