Abstract: This paper deals with the analysis of reinforced concrete (RC) structures with special emphasis on modeling of the interaction between concrete and reinforcement. A new mode for consideration of the response of the composite ...

Abstract: The proposed mode of consideration of the steel-concrete interaction (Part I) is applied to real-life engineering structures. Two structures recently investigated numerically at Vienna University of Technology are considered: ...

Abstract: This paper deals with the application of an adaptive calculation scheme to ultimate load analyses of reinforced concrete (RC) plates and shells. The influence of the user-prescribed accuracy on the numerical results, ...

Abstract: This paper contains the description of an adaptive calculation scheme for nonlinear (elastoplastic) finite element (FE) analysis. The underlying error estimator accounts for the error in the elastic regime as well as for ...

Abstract: The low viscosity of asphalt concrete at

Abstract: According to the New Austrian Tunneling Method (NATM), after excavation of a cross section of a tunnel, shotcrete is applied onto the tunnel walls, constituting a thin flexible, closed shell. Deformations, as well as the ...

Abstract: An assessment of the structural performance of concrete tunnel linings under fire load is presented for the Lainzer Tunnel, a shallow tunnel recently constructed in Austria. Prior to the installation of the concrete lining ...

Abstract: Freezing of water in porous media such as soil results in a change of mechanical and thermal properties. This change of properties is exploited during artificial ground freezing (AGF) employed in tunneling, during open ...

Abstract: This paper presents the application of three-dimensional (3D)-constitutive models for concrete formulated in the framework of plasticity theory to structural analyses of anchor devices. For this purpose, two commonly ...

Abstract: The transport and mechanical properties of saturated soil drastically change when temperatures drop below the freezing temperature of water. During artificial ground freezing, this change of properties is exploited in order ...
