Assessment of the Probability of Collapse of Structures Under Earthquakes

Dimitrios Lignos

Avoidance of collapse is the most important objective in earthquake resistant design, but assessing the probability of collapse of a structure during an earthquake is technically challenging and it is computationally demanding. This paper summarizes recent ...

Centrifuge modeling of mitigation-soil-foundation-structure interaction on liquefiable ground

Significant progress has been made in recent years toward a better understanding of the liquefaction phenomena. Yet, the combined effects of excess pore pressure generation, permanent soil deformation, and ground shaking, with and without mitigation, on th ...

Spectral shape metrics and structural collapse potential

Dimitrios Lignos

This paper examines various parameters that provide a measure of spectral shape and studies how they relateto the potential of ground motion records to cause the collapse of a given structure. It is shown that whenmeasuring the ground motion intensity by t ...

Displacement-based seismic design of symmetric single-storey wood-frame buildings with the aid of the N2 method

Katrin Beyer, Panagiotis Mergos

This paper presents a new methodology for the displacement-based seismic design of symmetric single-storey wood-frame buildings. Previous displacement-based design efforts were based on the direct displacement-based design approach, which uses a substitute ...

Wind-tunnel study of the wake behind a vertical axis wind turbine in a boundary layer flow using stereoscopic particle image velocimetry

Fernando Porté Agel, Vincent François-Charles Rolin

Stereo particle image velocimetry is used in a wind-tunnel to study boundary layer effects in the wake behind a vertical axis wind turbine. The turbine is a three-bladed giromill with a solidity of 1.18. The wake is studied for a tip speed ratio of 2 and a ...

Loading protocols for European regions of low to moderate seismicity

Katrin Beyer, Panagiotis Mergos

Existing loading protocols for quasi-static cyclic testing of structures are based on recordings from regions of high seismicity. For regions of low to moderate seismicity they overestimate imposed cumulative damage demands. Since structural capacities are ...
