Inclusion des contours de poteaux
<\/span><\/span><\/h2>\n
<\/p>\n

Pour am\u00e9liorer la pr\u00e9cision et optimiser les r\u00e9sultats des v\u00e9rifications du poin\u00e7onnement \u00e0 partir des r\u00e9sultats en \u00e9l\u00e9ments finis, <\/span><\/span><\/span>les contours de poteaux seront toujours d\u00e9coup\u00e9s du maillage en \u00e9l\u00e9ments finis pour les planchers-dalles et les radiers.  Voici le d\u00e9tail : <\/span><\/p>\n

<\/span><\/p>\n

    \n
  1. Tous les contours de poteaux sont automatiquement inclus dans le maillage EF, sauf en pr\u00e9sence de poutres ou de voiles de liaison. <\/span><\/span><\/span>
    <\/span><\/li>\n
  2. En d’autres termes, l’option \u00ab Inclure les contours de poteaux \u00bb ne contr\u00f4le que les poteaux avec poutres de liaison.<\/span>
    <\/span><\/li>\n
  3. Les contours de section ne sont pas inclus dans le maillage EF pour les poteaux avec chapiteaux.<\/span>
    <\/span><\/li>\n
  4. Les contours de section ne sont pas inclus dans le maillage EF pour les poteaux situ\u00e9s \u00e0 l’int\u00e9rieur (ou aux angles) des voiles de contreventement.<\/span><\/span> <\/span><\/span><\/li>\n<\/ol>\n<\/div>\n

    \n

    La m\u00e9thodologie<\/b><\/span><\/span><\/span><\/span>
    <\/span><\/h2>\n

    <\/p>\n

    La valeur maximale de la contrainte de cisaillement est obtenue en collectant les r\u00e9sultats sur le p\u00e9rim\u00e8tre de poin\u00e7onnement, qui peut \u00eatre rectangulaire, circulaire ou irr\u00e9gulier selon la g\u00e9om\u00e9trie du poteau et de la dalle.<\/span><\/span><\/div>\n

    <\/span><\/div>\n

    Les r\u00e9sultats sont collect\u00e9s pour chaque combinaison et la valeur enveloppe est retenue.<\/span><\/span><\/span><\/span><\/span><\/div>\n

          <\/div>\n
    Figures ci-dessus : contours de cisaillement V23 et points de station de poin\u00e7onnement pour les combinaisons enveloppes dans le post-processeur d’analyse.<\/span><\/i><\/span><\/div>\n

    Figures ci-dessus : chapiteaux de poteaux, p\u00e9rim\u00e8tres de poin\u00e7onnement et contours de cisaillement affich\u00e9s simultan\u00e9ment sur le plan physique du plancher<\/span><\/i><\/span>
    <\/div>\n
    <\/div>\n
    La m\u00e9thodologie et la formulation varient selon les codes de calcul. En principe, si la r\u00e9sistance \u00e0 la traction du b\u00e9ton suffit \u00e0 elle seule \u00e0 contrer les contraintes de poin\u00e7onnement autour du p\u00e9rim\u00e8tre de poin\u00e7onnement, aucune armature de poin\u00e7onnement suppl\u00e9mentaire n’est calcul\u00e9e. <\/span><\/span><\/span><\/span><\/span><\/div>\n
    Si la contrainte de poin\u00e7onnement d\u00e9passe la r\u00e9sistance \u00e0 la traction du b\u00e9ton, ProtaStructure calcule l’armature de poin\u00e7onnement.<\/span><\/span><\/span><\/span><\/span><\/div>\n
    \n
    \"Notes\"<\/p>\n
    L’armature existante de la dalle et l’armature de renfort local suppl\u00e9mentaire (le cas \u00e9ch\u00e9ant) sont prises en compte comme armature de poin\u00e7onnement.<\/span><\/div>\n
