26 February 2021

We are pleased to inform you that the 79th edition of the FABIG Newsletter is now available on the FABIG website.

FABIG Members are able to download Issue 079 from the Technical Newsletters section of the website (once logged-in) whilst non-Members of FABIG are able to purchase it.

This issue comprises the following:

  • Editorial: '30 Years of Fire and Blast Engineering: A Structural Engineer's Perspective'
    R. Brewerton - Inoventech
  • Modelling of masonry cavity cladding systems under blast loading
    J. Gu, L. Macorini, B. A. Izzuddin - Imperial College London, Computational Structural Mechanics Group
    This paper presents detailed and simplified modelling approaches for masonry cavity cladding systems. A detailed finite element modelling approach, utilising a mesoscale description for masonry, is first presented and validated against experimental results. Its application to typical masonry cavity cladding systems under a range of blast loading is then investigated via a parametric study, including the dynamic response of the cavity system and its ability to transfer blast loads to the surrounding frame. Finally, a simplified SDOF model is presented, which is shown to provide reasonable predictions of the transfer of blast load from the masonry cavity cladding panels to the surrounding structure.
  • Updates on fire resistance design of steel joints in EN 1993-1-2
    Y. C. Wang - University of Manchester
    During the recent revision of structural Eurocodes, the recommendations for fire resistance design of steel joints in EN 1993-1-2 have been updated. These updates are concerned with calculations of temperatures in joint components and additional recommendations for welded tubular steel joints. This short article presents these updates and summarises the background research studies that support these changes.
  • Blast wave time of arrival: A reliable metric to determine pressure and yield of high explosive detonations
    S. E. Rigby - University of Sheffield, Department of Civil & Structural Engineering
    This article summarises recent research by the author on the topic of blast wave Time Of Arrival (TOA). Firstly, high repeatability of TOA measurements is demonstrated through a compilation of far-field arena testing. Subsequently, two studies are discussed, where TOA was used to infer near-field reflected blast pressure distributions, and to estimate the yield of the 2020 Beirut explosion.
