摘要： PROBLEM TO BE SOLVED: To provide a high tensile bolt frictional joining method capable of inhibiting effectively a strength decrease in case of a fire. SOLUTION: This joining method involves fastening structural frame members together with high tensiIe bolts 6, 10 via washers 7, 8, 11, 12 and joining plates 4, 5, for the high tensile bolt frictional joining of the structural frame members. In that case, a material having a greater coefficient of linear expansion than the structural frame members is used for at least either the washers 7, 8, 11, 12 or the joining plates 4, 5.

摘要： PROBLEM TO BE SOLVED: To provide a fire-resistance design method for a prestressed member which enables the strength of the prestressed member at a high temperature to be rationally evaluated only by an analysis without referring to cross-sectional specifications of the member, and without performing an experiment etc.
SOLUTION: The high-temperature flexural strength Mu(t) of the prestressed member is estimated by an expression: Mu(t)=Σκ×ati×σyi(t)×di. In the expression, σyi(t) represents the yield strength of each prestressed wire rod which is obtained based on the temperature history of the prestressed wire rod after fire breaking determined by a heat transfer analysis of the cross section of the prestressed member, and the yield strength of the prestressed wire rod against the temperature; ati represents each cross-sectional area; di represents a distance from the compressed edge of the prestressed member to each of the prestressed wire rods; and κ represents a flexural strength coefficient. Subsequently, a retained fire-resistive period is estimated by putting the magnitude of the bending moment obtained based on a dynamic boundary condition in contrast with the high-temperature flexural strength, and the cross-sectional shape etc. of the prestressed member are set so that the retained fire-resistive period can become longer.
