Society for Earthquake and Civil Engineering Dynamics
SECED 2015 was a two-day conference on Earthquake and Civil Engineering Dynamics that took place on 9-10th July 2015 at Homerton College, Cambridge.
This was the first major conference to be held in the UK on this topic since SECED hosted the 2002 European Conference on Earthquake Engineering in London.
The conference brought together experts from a broad range of disciplines, including structural engineering, nuclear engineering, seismology, geology, geotechnical engineering, urban development, social sciences, business and insurance; all focused on risk, mitigation and recovery.
SECED 2015 featured the following keynote speakers (affiliations correct at the time of the conference):
A macro-element model, developed for the analysis of the cyclic in-plane lateral behaviour of masonry walls, has been modified to include second order effects, significant in case of large lateral displacements. The modified macro-element can be used to study a variety of local phenomena typical of masonry structures, ranging from those associated with the out-of-plane response of masonry walls to the in-plane response of arch systems and the static stability of walls with eccentric vertical load. Taking advantage of an internal rotational degree of freedom, second order effects are considered by additional moments in the nonlinear correction phase. The modified macro-element model is then suitable for studying the rocking response of walls and other masonry sub-systems. The model can be used to represent a macro-block in a kinematic chain of non-rigid bodies or, when used to simulate the wall out-of-plane behaviour, it can be adopted in a more refined mesh.
