Structural safety assessment of concrete tunnel lining subjected to fire / de Silva, D (Naples U.) ; Andreini, M (CERN) ; Bilotta, A (Naples U.) ; De Rosa, G (Naples U.) ; La Mendola, S (CERN) ; Nigro, E (Naples U.) ; Rios, O (CERN)
The basis of a possible fire design and verification approach to the linings of RC tunnels, using the performance-based approach, is presented. Starting from an extensive literature review, a selection of the most relevant tunnel fires was analysed. [...]

Identification and characterization of design fires and particle emissions to be used in performance‐based fire design of nuclear facilities / Perović, Darko (Lund U.) ; Van Hees, Patrick (Lund U.) ; Madsen, Dan (Lund U.) ; Malmborg, Vilhelm (Lund U.) ; Gren, Louise (Lund U.) ; Pagels, Joakim (Lund U.) ; Rios, Oriol (CERN) ; La Mendola, Saverio (CERN)
CERN operates one of the most complex particle accelerator facilities in the world.Several different hazards, including fires, are present and need to be investigated and reduced to a tolerable level. Toward this goal, CERN aims at developing a catalog containing detailed fire dynamics descriptions of combustible items present in its facilities. [...]

A fire safety assessment approach for evacuation analysis in underground physics research facilities / Ronchi, Enrico (Lund U.) ; Arias, Silvia (Lund U.) ; La Mendola, Saverio (CERN) ; Johansson, Nils (Lund U.)
This paper introduces an integrated approach for evacuation assessment of nuclear physics research facilities exposed to fire risk. The approach combines the use of a simplified egress modelling method and advanced agent-based simulations of evacuation. [...]

Long-term performance of a concrete-lined tunnel at CERN / Di Murro, Vanessa
At the world’s largest physics centre for nuclear research (CERN) under controlled laboratory conditions, two high-energy particle beams travel close to the speed of light around the most powerful particle accelerator ever built [...]

Discrete Structural Systems Modeling: Benchmarking of LS-DEM and LMGC90 with Seismic Experiments / Zhou, Ziran (Caltech) ; Andreini, Marco (CERN) ; Sironi, Luca (CERN) ; Lestuzzi, Pierino (Unlisted, CH) ; Andò, Edward (Unlisted, CH) ; Dubois, Frédéric (Montpellier U.) ; Bolognini, Davide (Unlisted, IT) ; Dacarro, Filippo (Unlisted, IT) ; Andrade, José E (Caltech)
Various papers have presented different methods for computations of mechanics and kinematics of discrete structural systems. However, little has been done in comparing and benchmarking the seismic response from two different discrete-system-models with experiments. [...]

Monetary optimization and quantitative risk acceptance criteria: From theory to practice / Fischer, Katharina (speaker) (Matrisk GmbH)
Fire safety codes around the world are based on two different approaches to regulate building fire safety: Prescriptive or performance-based design. The prescriptive approach, as implemented in most traditional fire safety codes, allows for a simple and effective risk control for the majority of buildings, but offers little flexibility to the designers and is difficult to apply in specific situations. [...]

Shaking table tests for seismic stability of stacked concrete blocks used for radiation shielding / Sironi, Luca (CERN) ; Andreini, Marco (CERN) ; Colloca, Cristiana (CERN) ; Poehler, Michael (CERN) ; Bolognini, Davide (Pavia U.) ; Dacarro, Filippo (Pavia U.) ; Lestuzzi, Pierino (Ecole Polytechnique, Lausanne) ; Dubois, Frédéric (U. Montpellier 2, LUPM) ; Zhou, Ziran (Caltech) ; Andrade, José E (Caltech)
This paper describes the shaking table tests carried out at the European Centre for Training and Research in Earthquake Engineering (EUCENTRE) to investigate the seismic behaviour of four configurations of stacked concrete blocks, commonly used at the European Organisation for Nuclear Research (CERN) as a shielding barrier against different types of radiation. The blocks used for these configurations have been designed to guarantee an adequate level of protection to radiation and, at the same time, to be easily transported and managed for different installations.

Automated pixel-level crack monitoring system for large-scale underground infrastructure – A case study at CERN / Ouyang, Aohui (CERN ; University Coll., Cork) ; Di Murro, Vanessa (CERN) ; Cull, Martin (CERN) ; Cunningham, Roddy (CERN) ; Osborne, John Andrew (CERN) ; Li, Zili (University Coll., Cork)
In concrete tunnel linings, cracks usually appear and develop as an early sign of structural degradation prior to severe intolerable serviceability damage. The monitoring and assessment of crack spatial distribution can highlight long-term tunnel structural behavior and facilitate tunnel maintenance. [...]

Investigating office buildings evacuations using unannounced fire drills: The case study of CERN, Switzerland / Rahouti, Anass (U. Mons) ; Lovreglio, Ruggiero (Massey U., Albany) ; Dias, Charitha (Qatar U.) ; Kuligowski, Erica (RMIT U.) ; Gai, Giordana (CERN) ; La Mendola, Saverio (CERN)
The main objective of this paper is to explore evacuees’ behaviour during an unannounced fire drill using data collected in two office buildings located at CERN, in Switzerland. Overall, a total of 142 pre-evacuation time measurements, 121 evacuee walking speed measurements in staircase configurations, and 336 evacuee walking speed measurements on floor configurations are included in the dataset.
