●墙问题（1）：在03G101－1图集中剪力墙竖筋在顶端要求锚入板中有个锚固长度，当剪力墙顶有暗梁AL时，是否只需锚入AL够锚固长度即可？
■答墙问题（1）：剪力墙竖向钢筋弯折伸入板内的构造不是“锚入板中”（因板不是墙的支座），而是完成墙与板的相互连接。暗梁并不是梁（梁定义为受弯构件），它是剪力墙的水平线性“加强带”。暗梁仍然是墙的一部分，它不可能独立于墙身而存在，所以，当墙顶有AL时，墙竖向钢筋仍然应弯折伸入板中。

●墙问题（2）：剪力墙钢筋、AL钢筋之间相互关系是怎样，图集中为什么不画出？端头直钩是从面筋上过，还是从下面过？直钩所在板中的位置是否有要求？在图集中剪力墙竖筋要求穿越AL，是否理解为剪力墙竖筋从AL钢筋中穿过，若这样剪力墙竖筋保护层又增加了一个AL钢筋直径？
■答墙问题（2）：比较合适的钢筋绑扎位置是：（由外及内）第一层为墙水平钢筋（水平钢筋放在外侧施工方便），第二层为墙竖向钢筋及AL箍筋，第三层为AL纵向（水平）钢筋。端头直钩与AL箍筋为同一层面，所以从面筋上过。墙筋直钩在板中的位置要看板面标高与墙顶标高的关系（特殊情况下二者可能有较小的高差），当二者一平时，墙筋直钩位置在板的上部。

● 墙问题（3）： 剪力墙端部有暗柱时，剪力墙水平钢筋应该伸入柱钢筋内侧还是外侧，现实中大多数工地都是伸入暗柱主筋外侧，我觉得这样不妥，但图集上没有详细规定，正确的做法应该是怎么样的？

● wall problem (1): 03G101-1 plan in the vertical shear reinforcement concentrated at the top requested anchor into the anchor plate has a length, when the wall when the top of a dark beam AL, AL is just enough to anchor into the anchor length can?
■ A wall of questions (1): vertical bar bent wall plate inserted into the structure is not "anchored into the board" (not the wall of the bearing due to plate), but the completion of the wall and the board connected. Dark beam is not the beam (Liang Dingyi as bending members), which is the level of linear wall "Strengthening the zone." Dark Beam is still a part of the wall, it can not exist independent of the wall, so when top of the wall have AL, the wall vertical reinforcement should still be inserted into the plate bending.

● wall problem (2): Shear Walls, AL What is the relationship between reinforcement, why not draw the graph focus? End hook straight on over from the gluten, or from following through? Direct hook plate in the position where there requirements? Concentration of shear wall vertical bars in Figure requested through the AL, if interpreted as vertical shear reinforcement in the cross bar from the AL, if the vertical shear reinforcement that adds another layer of protection AL bar diameter?
■ A wall of questions (2): more appropriate steel banding position: (from the outside and inside) the level of the first layer of reinforcement for the wall (horizontal bar on the outside of easy construction), the second layer vertical wall reinforcement and hoop AL bars, the third layer AL vertical (horizontal) reinforcement. End hook and straight AL stirrups for the same level, so too from gluten on. Direct hook in the wall bar in the position to Kanban board surface elevation and the top of the wall elevation relationship (special circumstances may be smaller height difference between the two), when both a normal, straight wall reinforcement in the plate upper hook position.

● wall problem (3): end of a dark column wall, the wall should be inserted into the column level of reinforcement steel inside or outside, in reality, most sites are inserted into the outer dark brick Configuration, I think This is wrong, but provided no details on the Atlas, the correct way is how like?
