Infilled frames have been investigated experimentally and theoretically by many researchers during last decades. It is noted that frame structures incorporating infill walls have shown definite economic and performance advantages over conventional rigid frame structures, especially when the structures are required to resist large lateral loads due to earthquake ground motion. However, there are a number of complicated failure mechanisms that can be caused by the frame-walls interaction. The reinforced concrete (RC) infill itself may fail in a variety of ways, most often involving some combinations of bed joint sliding, corner crushing, and diagonal cracking. Flexible frames on their own offer little resistance to lateral forces, resulting often in large deflections and rotations at the joints. On the other hand, walls subjected to lateral loads fail mainly in shear at relatively small displacements. Therefore, when the frames and wall act together, the combined action of the composite system differs significantly from that of the frame or wall alone. Strain-hardening cement composites (SHCC) are a class of high ductile fiber-reinforced cementitious composites developed for applications in the sensitive construction industry. The SHCC have undergone major evolution in both materials development and the range of emerging applications. The objective of the study is to evaluate infill wall system with particular attention to understanding the seismic response including failure mechanism and behavior of infill wall elements. The experimental investigation consisted of a cyclic loading tests on 1/3-scale models of infill panels. Material ductility and web panel reinforcement details were main variables in the experiment. The experimental results, as expected, show that the multiple crack pattern, strength, ductility and energy dissipation capacity are superior for SHCC infill wall due to bridging of fibers and stress redistribution in cement matrix.
