Abstract: Conventional approaches to the design and analysis of steel frames commonly assume the structure to be of either simple or rigid construction. In the simple construction approach, connections between members are not capable ...

Abstract: The paper presents the derivation of a deformation stiffness matrix for an asymmetric thin‐walled beam‐column element. This matrix

Abstract: A nonlinear finite element procedure for the pre‐ and postbuckling analysis of thin‐walled box‐section beam‐columns is presented. The influence of local plate buckling upon the overall ultimate buckling behavior of the ...

Abstract: The paper compares two elasto‐plastic models for incorporating the effects of material nonlinearity into a finite element procedure in the large deflection analyses of angle beam columns and trusses. These are the fiber ...

Abstract: A finite element method using thin‐plate elements is presented. The method is capable of predicting the buckling capacity of arbitrarily shaped thin‐walled structural members under any general load and boundary conditions. ...
