| Abstract: | Bearing capacity of slender compression members in concrete and masonry. Theoretical analysis about the bearing capacity of slender structural members use for the derivation of the bearing capacity reduction factors differential equation or numerical analysis. The analytical formulation by Hansen 4] delivers with similar assumptions as by Haller 2] a design concept with direct derivation of the eccentricity‐curvature relation and the bearing capacity for linear and non‐linear stress distribution in the section. In this paper the bearing capacity with rectangular stress distribution in the section has been derived in similar way. Using the limit term it's able to differ between cracked and uncracked sections. Another limit term defines, whether the section is in the buckling or the compression area. Depending on state and area the bearing capacity can be calculated directly. On the compressed side of the section it can lead to material softening. The stress decrees at the edge enlarge the curvature of the column and reduce bearing capacity. |
