Abstract
: A direct loss-based design (DLBD) procedure for reinforced concrete buildings has been recently proposed by the authors. It allows achieving a target acceptable level of earthquake-induced loss (e.g. deaths, dollars, downtime) under a specified site hazard profile. The procedure is called “direct” since the target loss level (e.g. defined based on client preferences) is specified at the first step of the procedure, and it generally requires two or three design iterations. The foundation of DLBD is a simplified loss assessment employing surrogate probabilistic seismic demand models and building-level damage-to-loss models for both direct and indirect losses. For a given target loss level, and structural geometry, the procedure provides the force-displacement curve of an equivalent single degree of freedom system. Such force-displacement curve becomes the target of the structural detailing phase, which is carried out using the principles of displacement-based design, thus allowing to design beams, columns, and walls accordingly. This paper illustrates the effectiveness of DLBD in designing a realistic RC case study building that achieves a 0.5% expected annual loss.
