HIGH-STRENGTH STRAND REINFORCEMENT FOR CONCRETE

A NEW THREE-WIRE STRAND, KNOWN AS BRISTRAND 100, HAVING A GUARANTEED 0.2% PROOF STRESS OF 100,000 LB/IN SQUARED, HAS BEEN DEVELOPED FOR USE AT A PERMISSIBLE WORKING STRESS OF 50,000 LB/IN SQUARES AS REINFORCEMENT IN NORMAL (I.E. NON- PRESTRESSED) CONCRETE CONSTRUCTION. THE DEVELOPMENT AND MANUFACTURE OF THE STRAND ARE EXPLAINED. DETAILS ARE GIVEN OF TESTS ON RECTANGULAR AND T-BEAMS REINFORCED WITH VARIOUS PERCENTAGES OF THREE-WIRE STRAND AND THE RESULTS OBTAINED ARE DISCUSSED AND COMPARED WITH THEORETICAL VALUES GIVEN BY A SUITABLE DESIGN METHOD. PARTICULAR ATTENTION IS PAID TO DEFLECTIONS AND CRACK WIDTHS, WHICH ARE OFTEN THE CRITICAL FACTORS CONTROLLING THE USE OF ULTRA-HIGH-STRENGTH STEEL AS REINFORCEMENT. /AUTHOR/
