SHEAR CAPACITY CALCULATION METHOD AND PRESTRESSED CONCRETE BEAM

摘要

PROBLEM TO BE SOLVED: To provide a shear capacity calculation method which can prevent the quantity of shear reinforcement from becoming excessive.;SOLUTION: A shear capacity calculation method for a prestressed concrete beam which has hole parts as a plurality of through-holes arranged in line calculates a shear capacity of a truss mechanism at the hole parts, calculates a shear capacity of a strut that is part of a truss mechanism imagined crossing between the hole parts, and calculates a shear capacity of an arch mechanism imagined consisting of a top chord and a bottom chord at the hole parts. Finally, the shear capacity of the beam is obtained as the sum of the shear capacity of the truss mechanism at the hole parts, the shear capacity of the strut crossing between the hole parts, and the shear capacity of the arch mechanism.;COPYRIGHT: (C)2012,JPO&INPIT
