Summary on Grant Application Form |

Building codes, including EUROCODE-8 assume vertical ground motion is around to 2/3 the horizontal ground motion. However, large vertical ground motions do occur particularly near to large magnitude events, and may equal or exceed significantly the local horizontal ground motion. In such situations existing code specifications must be considered unconservative. Furthermore, design spectra are independent of gravity and do not consider the coupling effects of horizontal and vertical motions.Observed damage due to vertical ground motion has been postulated, however there is no consensus. The proposed project therefore asks:1. does the vertical component of ground motion constitutive a significant proportion of the loading that has to be resisted by a building and its foundations?2. What is the likely general effect of the vertical motion on the stability of slopes, foundations and engineered structures?The work programme comprises tow tasks. Firstly, a statistical assessment of earthquake strong-motion records will e made to assess and predict the vertical and horizontal motion. The second task will examine the potential effects of vertical motion through simple models and derive appropriate design spectra.
