Abstract: Two built engineering examples were selected according to the layout of the shear wall structure with flat slab.Firstly, the elastic analysis under the frequent earthquake and wind load was carried out to complete the structural design.Then, the elastoplastic time-history analysis was completed under rare earthquakes to study its seismic performance andfailure modes. Finally, the economy of the shear wall system with flat slab was analyzed. The results show that under thefrequent earthquake and wind load, the whole index of the shear wall system with flat slab meets the requirements inTechnical specification for concrete structures of tall building ( JGJ 3—2010) , and the members checking also meets therequirements of bearing capacity, which can achieve the fortification goal of “ no damage during frequent earthquake” ;Under the rare earthquake, the inter-story drift angle of the shear wall system with flat slab meets the standard limit 1 / 120,and the damage of the wall and slab is not serious, which can achieve the fortification goal of “ no collapse during rareearthquake” ; Compared with traditional shear wall systems, the material amount used in the shear wall system with flat slabis slightly lower or the same. On the basis of the above, some suggestions were put forward for the slab thickness andsetting the hidden beam in the slab of the shear wall system with flat slab, which will provide references for the futureengineering application.

Keywords:shear wall system with large span flat slab; feasibility study; mechanical behavior; economy
