一、二级抗震纵向拉筋锚固LaE.doc

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=0.25m；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350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。
