Vous pouvez effectuer des v\u00e9rifications de poin\u00e7onnement selon le code b\u00e9ton s\u00e9lectionn\u00e9 \u00e0 l’aide de l’option \u00ab <\/b><\/span><\/span>V\u00e9rification du poin\u00e7onnement de poteau<\/b><\/span><\/span><\/i> \u00bb<\/b> situ\u00e9e dans l’onglet \u00ab <\/b><\/span><\/span>Calcul<\/b><\/span><\/span><\/i> \u00bb<\/b>.<\/span><\/span><\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

<\/div>\n
Les calculs de v\u00e9rification du poin\u00e7onnement ont \u00e9t\u00e9 con\u00e7us pour les structures en planchers-dalles et les radiers. La raideur des poutres de liaison \u00e9ventuelles n’est donc pas prise en compte dans les calculs.<\/span><\/span><\/div>\n
<\/div>\n
La v\u00e9rification du poin\u00e7onnement s’applique uniquement aux \u00e9l\u00e9ments s\u00e9lectionn\u00e9s. En l’absence de s\u00e9lection, tous les poteaux et voiles de l’\u00e9tage sont v\u00e9rifi\u00e9s.<\/span><\/span><\/div>\n
<\/div>\n
<\/div>\n

<\/span><\/div>\n
Vous pouvez aussi s\u00e9lectionner un seul poteau ou voile, puis utiliser le menu contextuel du clic droit pour v\u00e9rifier l’\u00e9l\u00e9ment s\u00e9lectionn\u00e9.<\/span><\/span><\/div>\n

  1. Options de fusion des dalles – <\/span><\/span><\/b>Ces options sont utilis\u00e9es lorsque les p\u00e9rim\u00e8tres de poin\u00e7onnement ne sont pas trouv\u00e9s (g\u00e9n\u00e9ralement pour une g\u00e9om\u00e9trie de dalle complexe). Reportez-vous \u00e0 la partie sur la fusion des dalles du <\/span><\/span>Guide de calcul de la v\u00e9rification du poin\u00e7onnement de poteau<\/span><\/span><\/i><\/b> pour plus de d\u00e9tails.<\/span>
    <\/span><\/span><\/li>\n
    <\/span><\/div>\n
  2. V\u00e9rifier le p\u00e9rim\u00e8tre du poteau et V\u00e9rifier le p\u00e9rim\u00e8tre du chapiteau (actif uniquement si un chapiteau a \u00e9t\u00e9 d\u00e9fini) \u2013 <\/span><\/span><\/b>Ces options permettent d’activer ou de d\u00e9sactiver la v\u00e9rification de la capacit\u00e9 de cisaillement maximale au droit de la zone charg\u00e9e.<\/span>

  3. R\u00e9duction de p\u00e9riph\u00e9rie \u2013 <\/span><\/span><\/b>Il s’agit d’une marge pour les ouvertures non mod\u00e9lis\u00e9es ou susceptibles d’\u00eatre cr\u00e9\u00e9es ult\u00e9rieurement.<\/span>

  4. Inclure la charge \u00e0 l’int\u00e9rieur du p\u00e9rim\u00e8tre de poin\u00e7onnement \u2013 <\/span><\/span><\/b>Lorsque cette option est coch\u00e9e, la charge de cisaillement prise en compte diminue \u00e0 chaque p\u00e9rim\u00e8tre successif, car la surface charg\u00e9e \u00e0 l’int\u00e9rieur du p\u00e9rim\u00e8tre augmente. Lorsqu’elle est d\u00e9coch\u00e9e, la charge de cisaillement reste identique sur tous les p\u00e9rim\u00e8tres : la v\u00e9rification devient alors plus conservatrice.<\/span>
    <\/span><\/span><\/li>\n
    <\/span><\/div>\n
  5. Emplacement du poteau –<\/span><\/span><\/b> Dans ce champ, l’utilisateur doit choisir l’emplacement du poteau dans le plancher-dalle (int\u00e9rieur, de rive ou d’angle) afin de d\u00e9terminer l’\u00e9quation utilis\u00e9e pour la v\u00e9rification du cisaillement.<\/span>

        Pour les poteaux circulaires, le m\u00eame principe s’applique : BS8110 ne consid\u00e8re que des p\u00e9rim\u00e8tres rectangulaires id\u00e9alis\u00e9s. Les v\u00e9rifications doivent donc utiliser le param\u00e8tre rectangulaire plut\u00f4t que circulaire.<\/span><\/div>\n
