Nuclear Regulatory Commission. Office of Nuclear Regulatory Research. Division of Engineering Technology.; Sandia National Laboratories.]. a nuclear primary containment structure of a typical PHWR in India. The focus of this work is to estimate the seismic fragility of this structure considering a failure defined in terms of tensile.

The seismic fragility curves obtained using the proposed approaches are compared with those obtained using the conventional approach considering an elastic response spectrum and a linear elastic seismic analysis of the structure.

The IDA-based fragilities are found to be more realistic than those obtained using conventional by: 2. Key Words: Buildings, Seismic Assessment, Vulnerability, Fragility Analysis, Fragility Curve, Experiment 1.

Generate a set of earthquake acceleration time histories, which cover various levels of ground shaking intensity. Many historic buildings in old urban centers in Eastern Canada are made of stone masonry reputed to be highly vulnerable to seismic loads.

Seismic risk assessment of stone masonry buildings is therefore the first step in the risk mitigation process to provide adequate planning for retrofit and preservation of historical urban centers. This paper focuses on development of analytical Cited by: Keywords: Fragility analysis, scaling method, structural reliability and safety analysis, 1 ABSTRACT The commonly used method for calculation of seismic fragilities is the scaling method.

The Zion Nuclear Power Plant is being utilized as a reference plant and fragility descriptions are developed for specific and generic safety related equipment groups in Zion. Both equipment fragilities and equipment responses are defined in probabilistic terms to be used as input to the SSMRP event tree/fault tree models of the Zion systems.

In conclusion, from the analysis carried out for individual case studies with h = 9 m, it has been possible to define capacity and fragility curves which, although generalised, can be regarded as a valuable aid in the design and structural verification phases (Fig.
