JK System, a New Structural System and Construction Technology

A new structural system and construction technology, called JK system, is introduced in the current study.JK system is a box-type bearing wall system in which both gravitational and lateral loads supposed to be supported by interior and exterior JK walls. JK wall is a concrete shear wall constructed by lightweight/low strength expanded polystyrene (EPS) concrete and reinforced with a 3D interconnected steel mesh, called JK panel. Using a pre-validated numerical model, seismic performance of a 3-story residential building,constructed with JK system, is examined followed by required design procedure. Obtained results indicate that JK system, similar to other box-type structures, has quite good seismic performance due to its high level of redundancy, lightness, and ductility of the used EPS concrete.
