Compared with traditional precast concrete composite shear walls (PCCSWs) with two boundary elements adjacent to edges, the PCCSWs with multiple boundary elements investigated in this paper have extra boundary elements at the intersections with other shear walls. In this paper, low reversed cyclic loading tests were conducted on three full-scale shear wall specimens with multiple boundary elements under in-plane loading and two full-scale shear wall specimens under out-of-plane loading. The in-plane loaded specimens included a PCCSW with double precast layers (i.e. precast concrete double skin shear wall, PCDSSW), a PCCSW with single precast layer, and a cast-in-pace (CIP) control specimen, whereas the out-of-plane loaded specimens included a PCDSSW and a CIP control specimen. Test results revealed that all specimens failed in bending. The hysteresis loops of the precast composite specimens were stable but slightly pinching, which were similar to those of the corresponding CIP control specimen. Compared with the CIP specimens, the PCDSSWs showed similar energy dissipation. The loading capacity of the precast composite specimens was generally a little lower than that of the corresponding CIP specimen with difference not more than 15%. In the in-plane loading tests, the PCDSSW reached higher displacement ductility (2.45) than the CIP specimen (1.88), whereas the ductility of the PCCSW with single precast layer was relatively low. Regarding the specimens under out-of-plane loading, the ductility of the PCDSSW (3.83) was close to that of the CIP specimen (3.02). Moreover, the stiffness degradation of the precast composite specimens was found to be comparable to that of the control specimens. Based on the test results, a restoring force model was developed.

Precast structures for multi-storey buildings can be designed with economy, safety and high performance. However, depending on the height of the building and the intensity of the lateral loads, the lateral stability system must be carefully chosen in order to maximize the global structural performance. In Brazil, the most common method for lateral stability is achieved by moment resisting precast-frames, wherein the moment-rotation response of the beam-column connections are responsible to provide the frame action, which will govern the distribution of internal forces and the sway distribution along the building height. On the other hand, in Europe, bracing systems comprised by shear walls or infill walls are mostly used, wherein beam-column connections are designed as hinged. The aim of this paper is to present a comparison between these methods for lateral stability, applying nine structural simulations with moment resisting precast-frames, shear walls and infill walls solutions, divided in three groups - 3 building with 5 storeys (21 meters high), 3 buildings with 10 storeys (41 meters high) and 3 building with 20 storeys (81 meters high). All first storeys are 5 meters high, while all the others are 4 meters high. The results from all structural analyses are compared. As conclusion, while moment-resisting beam-column connections are more feasible for applying in low-rise precast buildings, the use of shear walls and infill walls are more efficient for tall buildings due to decrease of lateral displacements, having a reduction of second order effects but also increasing the reactions at the foundations of bracing elements.
