CONCRETE COLUMN DESIGN BY AASHO SPECIFICATIONS

THE AASHO SPECIFICATIONS OF CONCRETE COLUMN DESIGN FAIL TO ENSURE CONSISTENT AND UNIFORM RESULTS BECAUSE THE DESIGN METHOD FOR CRACKED AND UNCRACED SECTIONS YIELD DISSIMILAR ANSWERS TO THEIR COMMON BOUNDARY, AND BECAUSE IT IS LEFT TO THE DISCRETION OF THE DESIGNER TO WORK WITH A MODULAR RATIO OF EITHER N = 10 OR N = 20. A METHOD IS PROPOSED BY WHICH THE DEMONSTRATED INCONSISTANCIES CAN BE ELIMINATED AND INTERACTION DIAGRAMS ARE PRESENTED WHICH PERMIT THE DIRECT DETERMINATION OF REINFORCING REQUIREMENTS FOR THE MOST COMMON COLUMN CONFIGURATION INCLUDING THE CASE OF BENDING ABOUT TWO AXES. THE PROPOSED METHOD IS PURELY PRAGMATIC, APPLIES TO WORKING STRESS DESIGN ONLY, AND IS SOLELY INTENDED TO OFFER A CONVENIENT MEANS OF OBTAINING UNIFORM AND CONSISTENT RESULTS WITHIN THE FRAMEWORK OF THE CURRENT SPECIFICATIONS. /AUTHOR/
