In order to meet desired seismic performances, it is increasingly evident that engineers require reliable methods for the estimation of seismic demands on both structural and non-structural elements. To this end, current design codes incorporate simplified ...
Displacement-based seismic design and assessment procedures require as key input parameter estimates of displacement capacities of the critical elements. The displacement capacities of unreinforced masonry (URM) walls are typically determined by means of q ...
This paper quantifies the collapse risk and earthquake-induced economic losses of steel-frame buildings with special concentrically braced frames designed in urban California. A probabilistic building-specific loss estimation methodology that can explicitl ...
Abstract Performance-based earthquake engineering necessitates the development of reliable nonlinear analysis models that are able to simulate the behavior of structures from the onset of damage through collapse. These models provide engineering demand par ...
Unreinforced masonry (URM) structures are known to be rather vulnerable to seismic loading. Modern URM buildings with reinforced concrete (RC) slabs might, however, have an acceptable seismic performance for regions of low to moderate seismicity. In partic ...
This paper discusses an analytical study that quantifies the expected earthquake-induced losses in typical office steel frame buildings designed with perimeter special moment frames in highly seismic regions. It is shown that for seismic events associated ...
During the last decade, a number of hysteretic models have been developed to simulate complex deteriorating mechanisms observed in steel components such that earthquake-induced collapse risk can be reliably assessed. Such models are typically calibrated wi ...
The Naturally Buckling Brace (NBB) is a steel brace developed by the writers, which consists of a high-strength and low-yielding steel channel arranged in parallel with an intentional eccentricity along the brace length. The NBB deforms with a novel mechan ...

The reliable estimation of the seismic performance of structures requires quantifying the aleatory and epistemic uncertainties of the system parameters. This is efficiently achieved for a case study of a four-story steel moment-resisting frame through seve ...
The performance-based earthquake engineering framework utilizes probabilistic seismic demand models to obtain accurate estimates of building engineering demand parameters. These parameters are utilized to estimate earthquake-induced losses in terms of prob ...
