How to calculate the bending anchor, vertical reinforcement and additional reinforcement of the lower beam of civil air defense retaining wall

First of all, the foundation is a component that does not consider earthquake resistance; Therefore, the anchorage length of reinforcement is La (the landlord said LaE was wrong)11g101-3, page 73 of the atlas; The structure without cantilever at the end is marked as follows: the inner side of the steel bar extending to the end is bent15d; ; When the length of the straight section is ≧La, it is not necessary to bend. It is indicated in the lower left corner of the atlas that when the foundation beam with cantilever structure is LN'+HC ≦ la, it needs to be bent15d; ; Then it shows that ln'+HC > la cannot be bent; This is a literal understanding;
