剪力墙施工钢筋锚固浅析(国外英文资料) Shear wall construction of steel bar anchorage Chen dh (naval first engineering building) 【 abstract 】 this paper introduces the anchorage method of steel bar in shear wall from the analysis of the minimum anchor length of shear wall reinforcement. 【 keywords 】 anchorage, minimum anchor length, earthquake resistance grade, non-seismic grade. In shear wall construction, steel bar anchoring involves the main problem is how to calculate the anchorage length, from the structure durability, steel bar to the bearing part of the core ability as the steel bar anchoring length, but in all or part of the construction site often see steel anchor within the protective layer, still calculated by anchor length, the steel bar anchoring length is not enough or failure. Here, I start with the analysis of the minimum anchor length of the steel bar in the shear wall, and talk about the steel anchor in the shear wall. Minimum anchor length of steel bar in shear wall In the seismic shear wall reinforced the minimum anchorage length of la see the value of concrete structure design code (GBJ 10-89), the smallest anchorage length of seismic shear wall of reinforced laE values are: secondary seismic grade laE = la + 5 d; Three levels of earthquake resistance level = la. (a) 2. 1. Horizontal distribution reinforcement 10 or more d La (seismic laE) or higher The vertical distribution of reinforcement The anchor of horizontal bar when the wall is not dark (a) the t-node; (b) the Angle node (b) La (seismic laE) or higher La (seismic laE) or higher 10 or more d 1. 1. The anchorage of horizontal steel bars The anchor method of horizontal distribution reinforcement can be anchored by the shear wall at the end of the shear wall as shown in figure 1 and figure 2. The length of the horizontal segment of the column with the horizontal distribution of the column is less than the length of the horizontal segment of the column. The anchoring of vertical distribution The minimum ancho
