METHOD FOR CALCULATING MINIMUM CRACK INDEX OF CONCRETE STRUCTURE, AND CALCULATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device to quickly calculate a minimum crack index of a concrete structure using a portable mobile type personal computer without expensive dedicated software or a high performance personal computer.;SOLUTION: The concrete structure is classified into analysis models according to the structure forms. An analysis pattern is defined of which factor related to the minimum crack index of the concrete structure is selected for each classified analysis model. Based on the analysis pattern, temperature stress analysis is performed by the finite element method. An estimation formula is defined by performing multiple linear regression analysis with changed factor for each analysis model. Based on the estimation formula, the minimum crack index is calculated. A portable personal computer having calculation software of the minimum crack index by the estimation formula is also provided.;COPYRIGHT: (C)2009,JPO&INPIT
