[BOOK][B] Next generation seismic fragility curves for California bridges incorporating the evolution in seismic design philosophy

KN Ramanathan - 2012 - search.proquest.com
Quantitative and qualitative assessment of the seismic risk to highway bridges is crucial in
pre-earthquake planning, and post-earthquake response of transportation systems. Such …

Temporal evolution of seismic fragility curves for concrete box-girder bridges in California

K Ramanathan, JE Padgett, R DesRoches - Engineering Structures, 2015 - Elsevier
Fragility analyses is a powerful tool for the seismic risk assessment of highway bridges.
Multispan continuous concrete box-girder bridges account for the bulk of the California bridge …

Constraints on light dark matter particles interacting with electrons from DAMIC at SNOLAB

…, J Molina, S Paul, A Piers, P Privitera, K Ramanathan… - Physical review …, 2019 - APS
We report direct-detection constraints on light dark matter particles interacting with electrons.
The results are based on a method that exploits the extremely low levels of leakage current …

Results on low-mass weakly interacting massive particles from an 11 kg d target exposure of damic at snolab

…, CT Overman, A Piers, P Privitera, K Ramanathan… - Physical Review Letters, 2020 - APS
We present constraints on the existence of weakly interacting massive particles (WIMPs)
from an 11 kg d target exposure of the DAMIC experiment at the SNOLAB underground …

Improving text-to-sql evaluation methodology

…, JK Kummerfeld, L Zhang, K Ramanathan… - arXiv preprint arXiv …, 2018 - arxiv.org
To be informative, an evaluation must measure how well systems generalize to realistic unseen
data. We identify limitations of and propose improvements to current evaluations of text-to…

Acoustic emission monitoring of CFRP reinforced concrete slabs

S Degala, P Rizzo, K Ramanathan… - Construction and Building …, 2009 - Elsevier
Debonding of externally bonded carbon fiber reinforced polymer (CFRP) materials used for
repair of reinforced concrete elements is commonly observed and is often the critical limit …

Light-off criterion and transient analysis of catalytic monoliths

K Ramanathan, V Balakotaiah, DH West - Chemical Engineering Science, 2003 - Elsevier
A one-dimensional two-phase model is used to derive an analytical light-off criterion for a
straight channeled catalytic monolith with washcoat, in which the flow is laminar. For the case …

Snowmass2021 Cosmic Frontier: The landscape of low-threshold dark matter direct detection in the next decade

…, N Kurinsky, D McKinsey, K Ramanathan… - arXiv preprint arXiv …, 2022 - arxiv.org
The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in
the past few years. We summarize the science case for these searches, the recent progress, …

A comparison of pre-and post-seismic design considerations in moderate seismic zones through the fragility assessment of multispan bridge classes

K Ramanathan, R DesRoches, JE Padgett - Engineering Structures, 2012 - Elsevier
Vulnerability estimation as well as quantitative and qualitative assessment of the seismic
risk to highway bridges is crucial in obtaining reliable estimates of the resilience of highway …

Fractional order intensity measures for probabilistic seismic demand modeling applied to highway bridges

A Shafieezadeh, K Ramanathan… - Earthquake …, 2012 - Wiley Online Library
Probabilistic seismic analysis of structures involves the construction of seismic demand
models, often stated as probabilistic models of structural response conditioned on a seismic …
