PROBLEM TO BE SOLVED: To simply estimate a maximum cracking width of a newly-built wall-shaped reinforced concrete structure without performing any analysis which is complicated and which requires an enormous number of man-hours. SOLUTION: An estimated unit cracking width is calculated based on actual measurement data on cracking in the existing wall-shaped reinforced concrete structure which receives external restraint. An estimated average cracking width is calculated from the estimated unit cracking width and an estimated number of unit cracks. Then the maximum cracking width of the newly-built wall-shaped reinforced concrete structure which receives external restraint is estimated based on the relationship between the calculated estimated average cracking width, an actual measurement average cracking width, and an actual measurement maximum cracking width, both of which are obtained based on the actual measurement data on cracking.
