Abstract: A new concept of instantaneous secant stiffness is proposed and used for nonlinear elastic‐plastic analysis of steel space structures, which replaces the Newton‐Raphson technique (the instantaneous tangent stiffness method). ...

Abstract: A second‐order nonlinear analysis of steel space structures has been presented. Of the two types of nonlinearities, material and geometric, only geometric nonlinearity has been considered. The material of the structure ...

Abstract: Determination of scour depth is needed for economical design of bridge pier foundation. Currently, determination of design scour depth is mainly based on use of relationships for maximum scour depth in steady flow along ...
