Abstract: The moment magnifier method was introduced into design practice to eliminate the need for extensive calculations, based on the solution to a differential equation, for the second-order moments in slender columns. This ...

Abstract: The ACI standard 318-02 permits the use of a moment magnifier approach for the design of slender composite steel-concrete columns. This approach is strongly influenced by the effective flexural stiffness

Abstract: The ACI Building Code permits the use of the equivalent uniform bending moment diagram factor

Abstract: The composite steel-concrete beam-columns in which steel shapes are encased in concrete and second-order effects are significant were studied from 16 specimens loaded to failure. Loading included combinations of axial and ...
