It is often interesting for prefabrication purposes to keep the bottom reinforcement separate for each span. With prefabrication, however, a second difficulty occurs, namely nodes with a large number of protruding reinforcement bars are difficult and sometimes almost impossible to cast in place. A fitting solution to solve this problem is to keep the anchorage reinforcement as limited as possible by means of discontinuous anchorage.<\/p>\n

This means that the foreseen bottom reinforcement of the different spans is nowhere within the dimensions of the column and that we place extra anchorage bars, mostly a little more centred in the cross section (nearer to the section axis) and possibly in the second layer, to avoid conflicts with other bars.<\/p>\n

These anchorage bars are extended within the dimensions of the columns. They provide both anchoring in the columns and transfer to the actual bottom reinforcement. The required sections for these anchorage bars, the so-called anchorage sections, are indicated in the window \u00abDiameter determination<\/strong>\u00bb \"\"\u00a0there where the supports are located, just above the bottom reinforcement sections. We use the same workflow as described in this article<\/a>, to transform these sections into bars.<\/p>\n

Voor prefabricatie-doeleinden is het vaak interessant om de onderwapening per overspanning afzonderlijk te houden. Er evenwel nog een tweede moeilijkheid op, namelijk knopen met een groot aantal uitstekende wapeningsstaven moeilijk en soms haast onmogelijk op te gieten zijn. Een passende oplossing is de verankeringswapening zo beperkt mogelijk gehouden d.m.v. discontinue verankering.<\/p>\n

Hiermee wordt bedoeld dat de voorziene onderwapening van de verschillende overspanningen nergens binnen de afmetingen van de kolommen vallen, en dat bijkomende verankeringsstaven <\/strong>geplaatst worden, meestal iets meer centraal in de doorsnede (kleinere afstanden tot de doorsnede-as) en eventueel in de tweede laag om geen conflicten te krijgen met andere staven.<\/p>\n

Deze verankeringsstaven worden doorgetrokken binnen de afmetingen van de kolommen. Ze zorgen enerzijds voor de verankering in de kolom en anderzijds voor de overdracht naar de eigenlijke onderwapening. De benodigde secties voor deze verankeringsstaven, de zogenaamde verankeringssecties<\/strong>, staan in het venster \u00abDiameterbepaling<\/strong>\u00bb\u00a0\"\"\u00a0ter plaatse van de steunpunten juist boven de onderwapeningssecties aangeduid. We gebruiken dezelfde werkwijze als in dit artikel<\/a> om de theoretische secties om te zetten in een praktisch aantal staven.<\/p>\n

Il est souvent int\u00e9ressant, \u00e0 des fins de pr\u00e9fabrication, de conserver une armature inf\u00e9rieure distincte par port\u00e9e. Toutefois, la pr\u00e9fabrication entra\u00eene une deuxi\u00e8me difficult\u00e9: la pr\u00e9sence de nombreuses barres d’armature au droit des n\u0153uds \u00e0 couler complique souvent la coul\u00e9e du n\u0153ud, voire la rendent pratiquement impossible. Pour rem\u00e9dier \u00e0 ce probl\u00e8me, il convient de pr\u00e9voir que l’armature d’ancrage soit r\u00e9duite par le biais d’un ancrage discontinu.<\/p>\n

Ceci suppose que l’armature inf\u00e9rieure pr\u00e9vue pour les diff\u00e9rentes trav\u00e9es ne co\u00efncide jamais avec les dimensions des colonnes et que des barres d’ancrage suppl\u00e9mentaires soient plac\u00e9es, \u00e9ventuellement dans un deuxi\u00e8me lit, afin d’emp\u00eacher tout chevauchement avec d’autres barres.<\/p>\n

Ces barres d’ancrage permettent d’une part, l’ancrage dans la colonne et d’autre part, la transmission des efforts vers l’armature inf\u00e9rieure. Les sections n\u00e9cessaires de ces barres d’ancrage, commun\u00e9ment appel\u00e9es sections d’ancrage, sont indiqu\u00e9es dans la fen\u00eatre \u00abD\u00e9termination du diam\u00e8tre<\/strong>\u00bb \"\"\u00a0au droit des appuis, juste au-dessus des sections d’armature inf\u00e9rieure.\u00a0Nous utilisons la m\u00eame m\u00e9thode que dans cet article<\/a> pour convertir les sections th\u00e9oriques en un nombre pratique de barres.<\/p>\n
