INORGANIC BEARING SURFACE MATERIAL AND BEARING WALL

WIPO Patent Application WO/2024/024189

A1

Provided are: an inorganic bearing surface material for which an ultimate proof strength correction value is increased as much as possible by increasing a plasticity rate in order to enable a wall magnification to be increased; and a bearing wall which comprises this inorganic bearing surface material. The bearing surface material 50 is of an inorganic type and has a surface material width of less than 910 mm in a front view of the bearing surface material 50. Preferably, a proof strength value to be applied when calculating the wall magnification of the bearing surface material is determined by the ultimate proof strength correction value, among the four kinds of proof strengths given below, which is obtained by correcting the ultimate proof strength of the bearing surface material on the basis of the plasticity rate. (1) Yield strength Py (2) Ultimate proof strength correction value Pu' obtained by correcting ultimate proof strength Pu on the basis of plasticity rate µ (here, µ = δu/δv, δu represents ultimate displacement, and δv represents yield point displacement) (3) 2/3 of maximum proof strength Pmax (4) Proof strength when apparent shear deformation angle is 1/120 rad, or proof strength when true shear deformation angle is 1/300 rad
