在多层商铺、办公楼、教学楼以及宿舍的外廊设计中,多因排水原因要对外廊较室内降板150mm,此时悬挑次梁须做变截面处理(图1),11G101图集有该节点做法,但图集做法存在钢筋锚固长度较长的问题,在搭接段内需做箍筋加密(图2),较为浪费;变截面梁的另一种做法是直接按小截面梁拉通,室内梁采用插筋处理(图3)。

In the multi-storey shops, office buildings, dormitories and the design of the outer corridor, due to drainage reasons more than the outer corridor lower plate than the indoor 150mm, at this time to be sub-beam to do variable cross-section treatment (Figure 1), 11G101 Atlas have The node approach, but there is a problem of atlas of the anchor length of the atlas approach, to be done in the lap section stirrups encryption (Figure 2), more waste; another method of variable cross-section beam is directly according to the small section girder pass , Indoor beam reinforcement treatment (Figure 3).
