INFLUENCE OF CREEP AND SHRINKAGE OF CONCRETE ON COMPOSITE CONSTRUCTION

IN REINFORCED CONCRETE CONSTRUCTION THE TWO MATERIALS TO BE CONSIDERED ARE CONCRETE AND STEEL. THESE MATERIALS HAVE DIFFERENT PROPERTIES WHICH MUST BE TAKEN INTO ACCOUNT WHEN DESIGNING A CONCRETE STRUCTURE. SHRINKAGE, CREEP, AND ELASTICITY ARE TIME-DEPENDENT PROPERTIES WHICH, WHEN MODIFIED, WILL CHANGE THE STRESSES IN THE STRUCTURE. IF THE STRUCTURE IS DESIGNED FOR THE ULTIMATE LOAD, THE TIME- DEPENDENT PROPERTIES BECOME INTERNAL MODIFICATIONS AND CAN BE IGNORED. IF, HOWEVER, THE STRUCTURE IS DESIGNED ACCORDING TO THE THEORY OF ELASTICITY, THESE TIME-DEPENDENT FACTORS ARE IMPORTANT AND MUST BE CONSIDERED. IN THIS STUDY, A NEW METHOD IS GIVEN FOR CALCULATING THE EFFECT OF CREEP AND SHRINKAGE IN CONCRETE, THE CREEP OF STEEL, AND THE TIME- DEPENDENT INCREASES OF THE MODULUS OF ELASTICITY UPON COMPOSITE CONSTRUCTIONS OF REINFORCED OR PRESTRESSED CONCRETE. A BASIC FORMULA IS DERIVED. EXAMPLES OF ITS APPLICATION ARE GIVEN AND COMPARISONS ARE MADE BETWEEN OLDER METHODS OF CALCULATION AND THE ONE DESCRIBED HERE. A SATISFACTORY CORRELATION IS ACHIEVED. /AUTHOR/
