6 Conclusions This paper proposes a novel structure system, an infi lled rocking wall frame structure, in which the rocking wall behaves as a continuous component. In the system, rocking walls are embedded in a frame, which facilitates wall construction and avoids complexity in frame-wall connection. The seismic performance of the proposed system was investigated through a quasi-static cyclic test. For comparison, a reinforced concrete frame (RCF) model and an infi lled rocking wall frame (IRWF) model were designed faithfully following Chinese seismic design codes. The contributions of slabs, outof-plane beams, and footing beams were considered. Comparisons on capacity, stiffness, displacement, crack width, strain and damage mode were made. Critical joints were designed and verifi ed. Finite element models were built and calibrated, and column shear forces in the IRWF model were achieved and compared. The main conclusions are as follows.
(1) Capacity and initial stiffness are evidently improved in the IRWF model, with capacity at more than 2 times and initial stiffness at 2.7 times that of the RCF model. The IRWF model also demonstrated satisfactory self-centering ability and negligible residual drift.
(2) The rocking wall has promising control on displacement distribution. Inter-story drift remained uniform along the height. When the structural drift ratio was 1/50, drift was 39.3, 35.7 and 34.7 mm for the three stories, respectively.
