“…There are different approaches for its estimation, ranging from purely economic reasoning to more sensitive ones that consider human loss as irreplaceable. The flowchart of Figure 2 depicts the three steps of the LCCA, while a more details of the calculation procedure can be found in (Lagaros, 2007). In the first step of Figure 2, the characteristics of the problem are defined; i.e., the numerical model, the uncertainties considered and their type, the intensity measure adopted, and the engineering demand parameters used for deriving the capacity curve.…”

Design of economic structures adequately resistant to withstand during their service life, without catastrophic failures, all possible loading conditions and to absorb the induced seismic energy in a controlled manner, was subjected to intensive research so far. Costly and extremely sensitive equipment, vital in commerce, business, education, and/or health care represent the contents of the contemporary structural systems. Frequently, structures themselves are less valuable than their contents. Moreover, following a catastrophic natural disaster, local communities requires that communication and emergency centers, hospitals, police, and fire stations to be fully operational. In conventional constructions, high floor accelerations are encountered in case of stiff buildings or large interstory drifts in flexible ones. These structural performance characteristics cause difficulties in protecting both building and its contents. As an efficient alternative design practice, base-isolated structures are considered, compared to the conventional fixed-base one. A critical evaluation of optimized fixed and base-isolated reinforced concrete buildings is performed in this study, with respect to the initial and total cost taking into account the life-cycle cost.

In this work, fragility analysis is performed to assess two groups of reinforced concrete structures. The fi rst group of structures is composed of buildings that implement three common design practices; namely, fully infi lled, weak ground story and short columns. The three design practices are applied during the design process of a reinforced concrete building. The structures of the second group vary according to the value of the behavioral factors used to defi ne the seismic forces as specifi ed in design procedures. Most seismic design codes belong to the class of prescriptive procedures where if certain constraints are fulfi lled, the structure is considered safe. Prescriptive design procedures express the ability of the structure to absorb energy through inelastic deformation using the behavior factor. The basic objective of this work is to assess both groups of structures with reference to the limit-state probability of exceedance. Thus, four limit state fragility curves are developed on the basis of nonlinear static analysis for both groups of structures. Moreover, the 95% confi dence intervals of the fragility curves are also calculated, taking into account two types of random variables that infl uence structural capacity and seismic demand.
