| Summary: | Seismic Damage Avoidance Design (DAD) principle that incorporates rocking wall with armoured steel wall to foundation seat details are presented for a class of warehouse type building. The walls consist of a mix of seismic wall panels and non-seismic infill cladding panels. The seismic wall panels are used to seat the rafters. Lateral loads are transmitted via diaphragm action through a roof truss. This design procedure involves seven steps. A key step of this procedure is the evaluation of total effective damping which includes intrinsic, hysteretic and radiation damping arising from rocking of the wall panels. Damping reduction factors for short, medium and long periods for the seismic design demand spectrum are also considered. The design is confirmed and validated using nonlinear time-history analysis under various earthquake ground motions. © 2014 Korean Society of Civil Engineers and Springer-Verlag Berlin Heidelberg.
