The citadel of Machupicchu is probably the most famous Inca heritage site in Peru. Considering the seismically active region, this research is an attempt to perform a seismic risk analysis of the heritage structures at Machupicchu. A systematic approach is adopted for this purpose. Characteristic seismicity of the region, where these historical constructions are located, is discussed based on t...

This paper briefly reviews the development of earthquake resistant design of buildings. The state-of-the-art of seismic design is discussed from the viewpoint of the performance criteria of buildings. These are (a) serviceability from frequent minor-intensity earthquake motions, (b) repairability from an infrequent but major-intensity earthquake motion, and (c) life safety from the maximum poss...

The influence of the near-fault ground motion on the response of long-span bridges must be considered as a critical factor for seismic design because the response indicates different aspects from existing earthquake characteristics. Also, it is important to note that the safety index for the risk assessment of long-span bridges is determined based on the minimum expected lifecycle cost E(LCC). ...

Fault trees have long been used to estimate failure risk in earthquakes, especially for nuclear power plants (NPPs). One interesting application is that one can assess and manage the probability that two facilities - a primary and backup - would be simultaneously rendered inoperative in a single earthquake. Another is that one can calculate the probabilistic time required to restore a facility ...

A conceptual framework for the probabilistic performance-based seismic assessment of building structures that considers both model uncertainty and response sensitivity to ground motion modification is presented in this paper. A new damage model is proposed for the assessment of building performance to seismic loads. The model is derived at the material level and combined at the element, story a...
