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

In this paper, an advanced modelling technique is developed to predict the nonlinear cyclic response of circular RC columns using a new phenomenological hysteretic model for reinforcing bars. The model has been implemented in OpenSees and is intended to be used in conjunction with a nonlinear fibre beam-column element. A comparison between different reinforcing steel models is made. Through a comprehensive parametric study, the influence of inelastic buckling of vertical reinforcement on the cyclic response of circular RC columns is investigated. The results have been compared and validated against a set of experimental datasets. The proposed calibrated model accounts for the influence of inelastic buckling of vertical reinforcement, stiffness of horizontal ties and their interaction with vertical reinforcement, and fracture of vertical bars due to low-cycle fatigue on cyclic degradation of circular RC columns.
