PROBLEM TO BE SOLVED: To provide a method by which strain caused in concrete through drying shrinkage may be simply and accurately estimated.SOLUTION: In a method for estimating strain caused in concrete through drying shrinkage, an estimated value of the strain caused in concrete through drying shrinkage is calculated in accordance with first and second formulas. In these formulas, α is a correction coefficient based on a coarse aggregate, and W, C, G, γ, γ, γ, &egr;(t,t), t, h and V/S respectively mean the same as in prediction formulas described on p. 182 of "Recommendation for Practice of Crack Control in Reinforced Concrete Buildings (Design and Construction)" (edited by Architectural Institute of Japan and published in February, 2006). |
