TORSIONAL BEHAVIOR OF PLAIN HIGH-STRENGTH CONCRETE BEAMS

摘要: Test results of 13 rectangular plain high-strength concrete beams subjected to pure torsion are presented. The variable was the strength, with nominal strength ranging from 40 90 MPa (5800 13,000 psi). Coarse aggregate high crushing and having a fineness modulus were used along Type I portland cement. under failed suddenly violently smooth surface. skew-bending theory is found suitable for prediting torsional capacity beams, provided that splitting tensile taken represent strength.
