一、二级抗震纵向拉筋锚固LaE

1、使用说明1、本表计算数据长度均以“M为单位，根据03G1011平面整体表示方法构造详图第33页和第34页表示测制，本表所列钢筋长度仅对梁钢筋锚固长度计算使用。2、屋面梁锚入端柱及角柱的锚固长度不在本表所列之中，计算时应根据设计选类进行计算，分别查阅03G1011图集的第55、56、58、59页节点作法要求。3、表中xx.xd端锚即是LaE*0.4+15d；表中xxd中锚即是LaE。4、吊筋测算指一根钢筋的长度，测算时系按梁厚250计算，如果次梁为200或300时分别在表中长度增减50计算。5、梁柱箍筋计算：梁柱砼截面减去保护层的周长加锚固的长度分别为6.5=0.16m;8=0.20m;10=0

2、.25m;12=0.30m(即减保护层后的周长+锚固长度=1个箍筋的长度),抗扭、构造钢筋的拉筋，当梁宽w350时，拉筋直径为6mm梁宽350时，拉筋直径为8mm拉筋间距为非加密区箍筋间距的两倍。6、HPB普通I级圆钢锚固长度：(1) 一、二级抗震纵向拉筋锚固：中锚C20砼=36d;C25砼=31d;端头弯锚C20砼=29.4d;中锚C25砼=27.4d;C30砼=27d;端头弯锚=25.8d。(2) 三级抗震纵向拉筋锚固：中锚C20砼=33d;C25砼=28d;端头弯锚C20砼=28.2d;中锚C25砼=26.2d;C30砼=25d;C35砼=23d;端头弯锚C30砼=25d;C35砼=24
