s61: the displacement angle between the elastic-plastic layers of each floor is not more than 1/120, if not, the building scheme or the structural scheme is adjusted, and then the steps are repeated;
s62: developing the finished large warehouse top plate according to the major earthquake unconformable recheck level, adopting a reinforcement scheme which is the same as the step S51 when the requirements are not met, carrying out envelope design with the step S51, adjusting a building scheme or a structural scheme if the reinforcement is not available, and repeating the steps;
s63: rechecking the top plate of the transition layer according to the large shock non-yielding and the consideration of the internal force outside the plane surface, and carrying out envelope design with the step S52;
s64: rechecking the finished structural members in the first-level development stage according to performance targets consistent with those in the first-level development stage, adjusting a building scheme or a structural scheme when the requirements are not met and a reinforcement scheme which does not influence the operation of a large warehouse cannot be adopted, and repeating the steps;
s65: rechecking the structures of other secondary development stages except the steps S62, S63 and S64 according to a performance target consistent with the primary development stage, and carrying out envelope design with the calculation results of the steps S4 and S5;
s66: and (3) inspecting the force transmission path and characteristics of the structure under the action of the rare earthquake, performing stress analysis on the inclined second shear wall and the complex parts of the inclined second shear wall, the large reservoir layer top plate, the transition layer top plate connecting nodes and the like, and rechecking and adjusting the wall, the plate thickness, the reinforcing bars, the node structure and the like according to the stress analysis result, so that the structure can reach the performance target of being continuously used after being generally repaired when the structure is subjected to the action of the estimated rare earthquake.
