V\u00e9rification au poin\u00e7onnement du radier : p\u00e9rim\u00e8tre et limites<\/span><\/h2>\n
La v\u00e9rification au poin\u00e7onnement du radier couvre les cas suivants : <\/span><\/span><\/div>\n
\n
    \n
  1. La v\u00e9rification s’applique aux poteaux et aux voiles isol\u00e9s reposant sur le radier.<\/span>
    <\/span><\/li>\n
  2. Elle est impossible pour les voiles de noyau fusionn\u00e9s reposant sur le radier, car le p\u00e9rim\u00e8tre critique est irr\u00e9gulier. <\/span><\/li>\n
  3. Elle est impossible pour un radier sur pieux, car le p\u00e9rim\u00e8tre critique est complexe et d\u00e9pend de l’implantation irr\u00e9guli\u00e8re des pieux. <\/span><\/span><\/li>\n<\/ol>\n
    \n
    \"Idea\"<\/p>\n
    Terminez l’analyse EF du radier avant de lancer la v\u00e9rification au poin\u00e7onnement. Sans les donn\u00e9es de contrainte du sol, la v\u00e9rification ne peut pas \u00eatre effectu\u00e9e<\/span>. <\/div>\n

    Proc\u00e9dure de v\u00e9rification au poin\u00e7onnement<\/span><\/h2>\n
    Suivez les \u00e9tapes ci-dessous pour v\u00e9rifier le poin\u00e7onnement au niveau des fondations :<\/span><\/span><\/div>\n
      \n
    1. \n
      \u00c0 l’\u00c9tage 0, s\u00e9lectionnez un ou plusieurs poteaux.<\/span><\/span> <\/span>
      <\/span><\/span><\/div>\n<\/li>\n
    2. \n
      Cliquez sur <\/span><\/span> <\/span>V\u00e9rification du poin\u00e7onnement des poteaux<\/span><\/span><\/b><\/i> <\/span> dans l’onglet <\/span><\/span> <\/span>Poteau<\/span><\/span><\/b> <\/span><\/span>
      <\/span><\/div>\n<\/li>\n
    3. La bo\u00eete de dialogue de v\u00e9rification du radier ressemble \u00e0 celle des voiles et des poteaux. Elle comporte deux \u00e9l\u00e9ments en plus : une colonne \u00ab Pression du sol \u00bb et un champ pour la valeur \u00ab Pression moyenne du sol sur l’aire tributaire du poteau \u00bb. <\/span>

      Ajustez les r\u00e9glages si n\u00e9cessaire. Pour les autres param\u00e8tres de cette bo\u00eete de dialogue, reportez-vous \u00e0<\/span>       V\u00e9rification du poin\u00e7onnement des poteaux<\/a>.<\/li>\n
    4. Saisissez la valeur du D\u00e9calage de l’aire tributaire<\/b> dans le champ pr\u00e9vu. La pression du sol est d\u00e9tect\u00e9e automatiquement. <\/span><\/li>\n
      \"Notes\"<\/p>\n
      \u00ab D\u00e9calage de l’aire tributaire \u00bb <\/span><\/i><\/b>r\u00e8gle la pression du sol selon la distance \u00e0 partir du bord du poteau. Pour \u00e9tendre l’aire tributaire du poteau, augmentez la valeur de ce champ. La pression du sol s’adapte en cons\u00e9quence.<\/span><\/div>\n

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

    5. Cl<\/span>iquez sur <\/span>Calculer <\/span><\/b>pour g\u00e9n\u00e9rer le r\u00e9sultat sous forme de rapport.<\/span>
      <\/li>\n<\/ol>\n
      \"Notes\"\"Alert\" <\/p>\n
      \n
      Le radier se calcule aussi depuis le mod\u00e8le analytique EF des fondations, en consultant les contours As(d) en flexion.  Reportez-vous \u00e0 : Mod\u00e8le EF des \u00e9tages et des fondations<\/a><\/span><\/div>\n<\/div>\n
