The increasing use by engineers of nonlinear response history analysis requires that the characterization of seismic demand extend beyond relatively simple intensity measures to suites of acceleration histories. Consequently, issues related to the selection and scaling of acceleration histories for engineering applications have become critical.
How many time histories are required? How should they be selected and scaled? What are the pros and cons of alternative procedures in terms of their validity, efficacy and implications for nonlinear response?
These topics will be explored in this presentation, beginning with methods to define “design ground motions” and extending to practical procedures to select and scale time histories.
Les Ingénieurs en structure de Montréal souhaite la bienvenue à tous. L’entrée est libre. Si vous désirez recevoir un avis électronique des prochaines réunions, envoyez un courriel à Sylvie Boulanger.
