Response of Flexible Structures to Dynamic Wind Loading


1-day course

CPD Credit: 6.5 hours, C1

Course Aim

This course is intended as an introduction to the analysis and design of structures under dynamic wind loading conditions and explains the relevant principles and methods of structural dynamics. The course will include worked examples from practice. The course content focuses on structural dynamics and is designed to complement the ‘Wind Loading on Structures’ course which covers the basic quasi-static approach outlined in the Eurocode (IS EN 1991-1-4).

Course Overview

This course will provide an introduction to dynamic structural wind engineering. The purpose of this course is to introduce the concepts and methods of structural design and analysis for dynamic wind loading to practicing engineers. The dynamic effects of wind loading on flexible wind sensitive structures will be explored in detail in this course. The theoretical background, technical aspects and Eurocode provisions for the analysis and design of flexible structures exposed to dynamic wind loads will be explained.

Course Objectives:

Upon successful completion of the course, the participants should be able to:

Understand the differences between a static/dynamic wind loading situation and where each is applicable.

Calculate the along-wind dynamic response of a structure using the ‘gust factor’ approach (basis of Eurocode and other international standards).

Understand how the modal properties of a structure affect its response to dynamic forces.

Understand how wind loads are represented through power spectral density functions (PSDFs).

Apply time- and frequency-domain techniques for the dynamic identification of modal frequency and damping.

Understand methods of mitigating wind induced vibrations in engineering structures.

Course Programme:

Morning session
