With people's yearning for a better life,building structures are becoming more and more complex and more complex.The leaping structure is a newly formed structure in people's needs,which has a certain impact on the urban living experience of today's society.Nowadays,whether it is for civil or commercial buildings,many engineering designs adopt a structural design of the stratification layer to form a large space atrium to meet the needs of building functions.China's relevant design specifications stipulate that for the conventional planar building structure,rigid internal slabs can be used to calculate the internal force and displacement of the structure,and the calculation accuracy can meet the design requirements.However,for the irregular slabs with large holes,due to the lack of integrity of the floor,horizontal loads cannot be uniformly transmitted to the members subjected to the lateral force,which affects the internal force distribution of the building structure and makes the structure more stressed.complex.Therefore,research on such hop structure is necessary and urgent.According to the characteristics of large holes in the layer structure of the hop layer,different models are established and the corresponding calculations are carried out.The aim is to have some reference for similar structure types.The main research contents are as follows:(1)According to the characteristics of odd-numbered floor slabs,different structural models are defined.Different models are calculated by PKPM-SATWE,and the response of each model under earthquake is compared and analyzed to ensure the rationality of structural design.(2)Find the odd-numbered floor with complex stress,analyze the stress of the floor and the influence of different floors on the force.(3)Using the Midas Building to carry out static elastoplastic analysis of different design models,and study the differences and safety of each model under rare earthquakes,so as to guide the selection of the model and the optimization of structural design in the design of the hop structure.The results show that although the odd-level floor slab has a large opening area,in the case of multiple earthquakes,the influence of the elastic floor slab on the structure and the calculation of the rigid slab assumption on the structural calculation are limited in some respects.Under the action of the medium earthquake,the rigid floor assumes that the lower floor exhibits a large stress distribution.Under the action of rare earthquakes,the elastic shear wall structure assumed by elastic and rigid slabs can meet the requirements of large earthquakes and strong columns.
