IABSE has awarded the Outstanding Paper Award 2018 in the category ‘Scientific Paper’ to: “Considerations for Robustness in the Design of Steel and Composite Frame Structures”, by P. Stylianidis, D. Nethercot, UK SEI 2/2017 (May), pp. 263-280.
The topic of progressive collapse of structures has increasingly received particular
consideration over recent years, with numerous studies of various forms
seeking to explore the complex mechanics of the problem and define ways of
minimising its effects. Through a continuing research programme at Imperial
College London, considerable advance has been made in understanding the
physical features of the progressive collapse response of frame structures, identifying
the role of the several different controlling parameters and compiling
simplified methods for simulating particular effects. Knowledge of the subject
has therefore improved to a considerable extent, that it is now possible to make
quantitatively justified assessments of structural robustness by specifying the
reasons why a structure might be susceptible to progressive collapse as well as
to identify potential methods for enhancing performance. The present paper
reviews previous developments at Imperial, evaluates information obtained
from relevant experimental studies conducted by other research groups and
assesses the progress made both in developing a scientific understanding of the
subject and establishing improved ways of tackling the problem in practice.
Several factors that should be considered in the robustness design of steel and
composite frame structures are defined, and needs for further research into specific
aspects of the problem are identified.
