ABSTRACT: The American Concrete Pipe Association™s PipeCAR software is a useful tool widely used in Canadian practice for the design of reinforced concrete pipes. PipeCAR is based on AASHTO™s Load Resistance Factor Design (LRFD) Bridge Design Specifications, whereas Canadian codes use the Limit-States (LS) design method. Hence, its conformance with the Canadian Highway Bridge Design Code (CHBDC) requirements needs to be evaluated. In this paper, PipeCAR results were validated per the requirements of ASCE 15-98 and the AASHTO Bridge Design Specifications and were compared with CHBDC requirements. Additionally, the validity of the Heger pressure distribution used in all of the above standards is verified using finite element analysis under a several heights of fill and soil conditions in trench installations.
RÉSUMÉ: Le logiciel de PipeCAR de l'American Concrete Pipe Association est un outil utile dans la pratique canadienne pour la conception de tuyaux en béton armé. PipeCAR est basé sur « Load Resistance Factor Design (LRFD) Bridge Design Specifications » de AASHTO, alors que les codes canadiens utilisent les méthode de conception « Limit-States » (LS). Par conséquent, sa conformité avec le « Canadian Highway Bridge Design Code » (CHBDC) doit être évaluée. Dans cet article, les résultats ont été validés par PipeCAR aux exigences de l'ASCE 15-98 et AASHTO et ont été comparées avec les exigences CHBDC. En outre, la validité de la distribution de pression de sol à Heger, utilisé dans toutes ces normes, est vérifiée en utilisant l'analyse par éléments finis avec un plusieurs hauteurs de remplissage et conditions de sol dans les installations en tranchée.
