Earthquake Risk and Engineering towards a Resilient World

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

Overview

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

Review

Peru has a wealth of historic earthen architecture built after the arrival of the Spanish in the 16th century. However, little is known about the seismic behaviour of these buildings. This paper presents a decision-tree based diagnostic approach aimed at identifying the vulnerability of two traditional earthen buildings, and locating areas where strengthening can be implemented. The diagnosis is carried out in two stages; a preliminary diagnosis based on onsite observations, and a detailed, more quantitative diagnosis based on results of numerical analysis and experimental testing. At each stage, four parameters are assessed; the initial structural concept, the interaction between structural components, the quality of the connections, and the quality of the structural fabric. The effect of deterioration, and how this influences the other variables is also considered. The approach has been applied to two types of historic earthen buildings in Peru with very different structural systems. It is shown to be applicable to both building types, with only minor adaptations, and has proven to be a useful tool for identifying vulnerable aspects of the building.
