Abstract: | Es wird ein Rechenmodell vorgestellt, das zur Vorbemessung beim Nachweis der Querkrafttragfähigkeit älterer parallelgurtiger Spannbetonbrücken angewendet werden kann. Das Nachweisverfahren leitet sich aus dem Prinzip vom Minimum der Formänderungsenergie ab und berücksichtigt den Betontraganteil der Querkrafttragfähigkeit über den rechnerischen Ansatz einer begrenzten Mitwirkung der Betonzugfestigkeit. A model for pre-designing the shear bearing capacity of elder prestressed bridges It is presented a structural model that can be applied for pre-designing for the assessment of the shear bearing capacity of elder prestressed concrete bridges. The design procedure is derived from the principle of the minimum of strain energy and takes into account the part of concrete bearing capacity of the shear bearing capacity with a design approach of a limited involvement of the concrete tensile strength. |
