Earthquake Risk and Engineering towards a Resilient World

9 - 10 July 2015, Homerton College, Cambridge, UK


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.

Conference themes

  • Geotechnical earthquake engineering
  • Seismic design for nuclear facilities
  • Seismic hazard and engineering seismology
  • Masonry structures
  • Risk and catastrophe modelling
  • Vibrations, blast and civil engineering dynamics
  • Dams and hydropower
  • Seismic assessment and retrofit of engineered and non-engineered structures
  • Social impacts and community recovery

Transverse reinforcement in reinforced concrete (R/C) frame buildings designed to older seismic codes is typically inadequate, rendering their members vulnerable to shear failure subsequent, or prior, to yielding of their longitudinal reinforcement. This can eventually lead to loss of axial load-bearing capacity of columns and initiate vertical progressive collapse.

The development of a member-type model for the full-range response of substandard elements is presented herein. The basis of post-peak behaviour modelling is the ascription of post-shear failure deformations to shear strains alone and their concentration at a critical length defined by a diagonal failure plane. The parameters defining the critical angle of this plane and the in-cycle shear strength degradation after the onset of shear failure are identified and empirical models are put forward. To this end, a rather large database of experimental results of rectangular shear and flexure-shear critical R/C columns has been compiled.
