THE CONTROL OF TENSILE CRACKING IN REINFORCED CONCRETE HIGHWAY STRUCTURES

SINCE THE PUBLICATION OF THE MINISTRY OF TRANSPORT'S MEMORANDUM NO. 577/2 (REINFORCED CONCRETE FOR HIGHWAY STRUCTURES: MATERIALS, WORKMANSHIP, DESIGN REQUIREMENT AND PERMISSIBLE STRESSES, JUNE, 1968) THE CONTROL OF TENSILE CRACKING IN REINFORCED CONCRETE HIGHWAY STRUCTURES HAS BECOME A DESIGN REQUIREMENT WITH BOTH MILD AND HIGH TENSILE REINFORCEMENT. THIS CONTROL ON CRACKING IMPOSES SEVERE RESTRICTIONS ON THE STRESSES THAT CAN BE USED IN REINFORCED CONCRETE, AND SUBSTUNTIAL ECONOMIES CAN BE ACHIEVED BY RIGOUROUS DESIGN. TRIAL AND ERROR METHODS OF LIMITING CRACK WIDTH ARE NEITHER SATISFACTORY NOR ECONOMICAL. CRACK CONTROL IS A BASIC CRITERION OF DESIGN AND AS SUCH IT SHOULD BE CONSIDERED FROM THE OUTSET OF A DESIGN. A SIMPLE PROCEDURE FOR DOING THIS IS DEVELOPED IN THE SECOND HALF OF THIS ARTICLE. /UTHOR/
