ULTIMATE STRENGTH OF COMPOSITE BEAMS

SIMPLE METHODS OF PREDICTING THE ULTIMATE MOMENT OF RESISTANCE AND THE CURVATURE OF CROSS-SECTIONS OF COMPOSITE STEEL-CONCRETE BEAMS ARE PRESENTED, BASED ON RECENT RESEARCH ON THE STRESS/STRAIN CURVE FOR CONCRETE. THESE DESIGN METHODS ARE COMPARED WITH THE RESULTS OF LABORATORY TESTS AND WITH SIMULATED TESTS CARRIED OUT ON A COMPUTER. /RRL/A/
