Abstract: The hybrid stress method of finite elements as advocated by Pian and others is reviewed. Whereas variational methods are the most frequently used vehicle for formulating hybrid finite elements, the present communication ...

Abstract: For important structures, it is increasingly required that catastrophic failure of the entire structure be prevented. Failure of an element due to an accidental event must not result in progressive collapse of other elements ...

Abstract: A method of analysis of instantaneous and time‐dependent stresses and strains in prestressed noncracked cross sections of curved members is presented. The procedure is an extension of an existing method of analysis that ...

Abstract: A method of analysis is presented to predict the behavior of prestressed concrete structures with internal or external tendons up to ultimate. The structure is modeled as an assemblage of plane frame members connected at ...

Abstract: Unbalanced moments are transferred between columns and flat plates as a result of pattern gravity loading or lateral forces due to wind and earthquakes. Shear stresses produced by moment transfer must be considered in the ...

Abstract: A method is presented for prediction of stresses and strains of partially prestressed concrete structures. Members are assumed to be uncracked under permanent loads, but cracking can occur under transient live load. A ...

Abstract: Nonlinear temperature variation over the cross section of a simplysupported bridge produces longitudinal stresses (eigenstresses). In a continuous bridge, additional continuity stresses develop. Parametric studies are ...

Abstract: A method is presented for analysis of the stresses and strains in plane frames composed of straight noncracked reinforced concrete members with or withour prestressing subjected to large axial forces and/or supported on ...
