Quasi-static cyclic tests on super-lightweight EPS concrete shear walls

This study introduces a new emerging structural system, called JK system, which uses JK walls as its main structural elements. JK wall, first proposed by Joseph Kiefer, is a kind of shear wall constructed with lowstrength/super-lightweight Expanded Polystyrene (EPS) concrete and reinforced by JK panel, JK stiffener and some additional steel rebars. The study experimentally examines behavior of three JK wall specimens with different reinforcement and level of gravity loads under quasi-static cyclic loading. Obtained results indicate that JK walls can sustain large ductility demands accompanied by stable hysteresis loops.
