Composite Shear

The concept of steel-concrete composite shear wall is introduced due to the benefits achieved by integrating both the materials. These are structural walls, where steel profiles are encased at the boundary elements. Due to their higher lateral strength and stiffness, they offer a good alternative to improve earthquake resistance over conventional reinforced concrete shear walls in medium and high-rise buildings. Current literature shows that, design procedure of such composite shear walls is not addressed in developing country codes. Hence, a design of steel-concrete composite shear wall is proposed in the present paper on the basis of existing theory and with the help of standard codes. The web portion of shear wall has to be designed as per provisions of Eurocode 8. For the design of composite boundary elements, design norms of composite columns are followed. Also the design of shear stud connectors is adopted according to Eurocode 4.

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.

Composite Shear

To improve the seismic behavior of shear walls, a new composite shear wall composed of a steel-fiber-reinforced high-strength concrete (SFRHC) web and two square concrete-filled steel tube (CFST) columns, namely a steel-fiber-reinforced concrete shear wall with CFST columns, is proposed in this paper. Therefore, the main purpose of this paper is to present an experimental investigation of the seismic behavior of the SFRHC shear wall with CFST columns. Pseudo-static tests were carried out on seven composite shear walls, and the seismic performance of the shear walls was studied and quantified in terms of the aspects of energy consumption, ductility and stiffness degradation. Furthermore, the experimental results indicated that adding steel fiber can effectively restrain the crack propagation of composite shear walls and further help to improve the ductility and energy dissipation capacity of composite shear walls and delay the degradation of their lateral stiffness and force. Moreover, the seismic behavior of the SFRHC shear wall with CFST columns was obviously superior to that of the conventionally reinforced shear wall, in terms of load-bearing capacity, ductility, stiffness and energy dissipation capacity, because of the confinement effect of the CFST columns on the web. Finally, the preliminary study demonstrated that the composite shear wall has good potential to be used in regions with high seismic risk.
