Abstract: Lack of uniqueness of the kinematic solution of elastoplastic flexural frames is studied by deriving a general solution for nonholonomic behavior. A singular hinge set is defined as a collection ...

Abstract: A procedure for progressive nonholonomic analysis of elastoplastic plane frames neglecting axial force effects is developed. Within the framework of simple plastic theory the governing condition is expressed in terms of ...

Abstract: A method for predicting the torsional strength of a reinforced concrete beam containing a rectangular opening is developed using the principles of limit analysis. A simple yield criterion for yielding under combined bending ...

Abstract: This study presents a derivation of an exact relationship between the deflection values of a simply supported Mindlin plate and the corresponding simply supported Kirchhoff plate. The relationship is valid for any polygonal ...

Abstract: The elastic buckling of columns with allowance for prebuckling axial shortening is analyzed using Trefftz's initial stress theory of 1933 and the engineering strain definition; the results are compared with earlier results ...

Abstract: The paper considers the elastic buckling of skew plates subjected to in‐plane loadings. The buckling analysis is performed using the Rayleigh‐Ritz method with the newly proposed pb‐2 Ritz functions, which consist of the ...
