초록

This paper first provides a wide overview about the design codes and standards covering the use of Computational Wind Engineering / Computational Fluid Dynamics (CWE/CFD) for wind-sensitive structures and built environment. Second, the paper sets out the basic assumptions and underlying concepts of the new Annex T "Simulations by Computational Fluid Dynamics (CFD/CWE)" of the revised version "Guide for the assessment of wind actions and effects on structures" issued by the Advisory Committee on Technical Recommendations for Constructions of the Italian National Research Council in February 2019 and drafted by the members of the Special Interest Group on Computational Wind Engineering of the Italian Association for Wind Engineering (ANIV-CWE). The same group is currently advising UNI CT021/SC1 in supporting the drafting of the new Annex K - "Derivation of design parameters from wind tunnel tests and numerical simulations" of the revised Eurocode 1: Actions on structures - Part 1-4: General actions - Wind actions. Finally, the paper outlines the subjects most open to development at the technical and applicative level.

과제정보

The activity described in this paper was carried out under the umbrella of the Italian Association for Wind Engineering (ANIV): the authors acknowledge its support. Davide Fransos and Andrea Lo Giudice, former members of ANIV-CWE, contributed in the past to the group activities on CWE best practices and codification: the authors warmly thank them. The Annex T of the Guide CNR-DT 207-R1/2018 was strongly encouraged by Giovanni Solari and Franco Maceri: the authors gratefully acknowledge their stimuli. The Annex K of Eurocode 1-Part 1-4 has been first envisioned by Francesco Ricciardelli as member of the Project Team SC1.T3: EN 1991-1-4 (Wind) - Mandate M/515 Phase 2 tasks for the development of the 2nd generation of EN Eurocodes: the authors are grateful for his proposal to support the drafting of the part devoted to CWE. The figures included in the paper partially refers to data, results and studies obtained by Others. Three nomenclatures are used in the figure captions: i. if data are gathered, analyzed and reworked by the Authors, hence the term "source" is used; ii. if results are taken form published scientific and technical literature, hence the term "after" accompanied by a bibliographic reference is used; iii. if results are taken by unpublished industrial studies, the term "Credits:" accompanied by the name of the Company owner of the rights is used. It will be evident from the reference list that the authors are indebted to a large number of industrial and academic colleagues for much of the information that is included in this paper, and it is simply not possible to name them all. Their indirect valuable contribution is gratefully acknowledged.
