ProtaStructure prend en charge la v\u00e9rification d\u00e9taill\u00e9e de la fl\u00e8che \u00e0 long terme des poutres en b\u00e9ton arm\u00e9 selon les codes de calcul suivants : <\/span>
<\/span><\/span><\/div>\n
    \n
  1. Code am\u00e9ricain : ACI318-2014, ACI318-2019 <\/span><\/span>
    <\/span><\/li>\n
  2. Code colombien : NSR10-C <\/span><\/span>
    <\/span><\/li>\n
  3. Normes indiennes : IS456-200 <\/span><\/li>\n
  4. Code indon\u00e9sien : SNI2847<\/span><\/span>
    <\/span><\/li>\n

    <\/span><\/li>\n
  7. Code turc : TS500<\/a><\/span><\/li>\n<\/ol>\n
    <\/p>\n

    Cette v\u00e9rification calcule les inerties effectives des sections. Elle tient compte des armatures fournies et des moments de calcul. L’\u00e9tat de fissuration est ensuite d\u00e9termin\u00e9 sur appuis et en trav\u00e9e. Les fl\u00e8ches sont obtenues avec les inerties effectives. Elles suivent les combinaisons ELS d\u00e9finies par l’utilisateur et les conditions de service donn\u00e9es par les codes.<\/span><\/p>\n

    Les fl\u00e8ches \u00e0 long terme sont aussi calcul\u00e9es. Elles utilisent les facteurs d\u00e9pendant du temps et les dur\u00e9es de charge soutenue prescrits par les codes. Les r\u00e9sultats figurent dans un rapport d\u00e9taill\u00e9 sous forme de tableaux (exemple pour l’ACI ci-dessous) <\/span><\/span><\/p>\n
