Register For MSE Walls Stiffness Method Webinar

The versatility of the stiffness method of measurement for MSE walls design versus the simplified method will be explored at a webinar this month.

Join Professor Richard Bathurst when he discusses the ‘Development of the stiffness method for internal stability of MSE walls‘ on September 19.

The American Association of State Highway and Transportation Official’s (AASHTO) load and resistance factor design (LRFD) for bridge design, adopted the stiffness method for the internal stability design of geosynthetic mechanically stabilized earth (MSE) walls. The difference between this 2020 AASHTO LRFD code and the previous 2017 edition, which used the simplified method, will be explained during the webinar.

The stiffness method approach is described as a paradigm shift on how reinforcement loads are calculated in designing MSE walls and the lecture, hosted by IGS Iran, will describe how and why the method was developed, and share its impact on design outcomes.

The session runs from 3.30pm-5.30pm GMT or 8pm-10pm Iran time.

A shorter, Persian-language session runs an hour earlier at 2.30pm-3.30pm GMT and will include an introduction to the Iran chapter and Iranian geosynthetics companies, before a short talk based on the English version lecture by Prof. Bathurst. The Persian lecture is suitable for students and participants from Persian-speaking nations such as Iran, Afghanistan, Uzbekistan and so on, who may be less familiar with English.
