title = "Displacement based seismic design of asymmetric plan rc wall structures: Modal approach",
abstract = "The development of practical seismic engineering procedures which produce economical designs for asymmetrie plan R.C. wall structures is intended to help mitigate earthquake hazards. Earthquake related building damage corresponds more directly to deformations than to forces. Hence, for asymmetrie structures which exhibit highly nonlinear behaviour, a displacement-based design approach appears likely to produce safer and more economical designs than traditional linear force-based design methods. There are many analysis methods available for response prediction of designed buildings. However, most existing seismic design methods are either iterative at the multi-degree of freedom (MDF) structure level or consider an 'equivalent' single mode only and rely on empirical factors to account for torsional and higher mode effects. This paper presents two displacement-based seismic design methods referred to collectively as 'Modal Displacement Based Design' (MDBD) for single story asymmetrie plan RC wall structures which consider torsional and higher mode effects explicitly. The first method, called 'Modal Pushover Design' (MPD), is iterative at the single-degree of freedom (SOF) level and achieves performance targets exactly when verified by Modal Pushover Analysis (MPA). The second, called 'Direct Modal Pushover Design' (DMPD), is non-iterative. DMPD defines yield and design displacement profiles based on initial elastic and secant (to estimated peak ductility) element stiffness respectively.",
