Micro vs. macro models for predicting building damage underground movements

Truong Hong, Linh ; Laefer, Debra F. (2008-11)

For over 30 years various micro and macro models have been used for analysing masonry, but no strong consensus within the structural engineering community exists as to usage. Selection remains driven by field scenarios, ...
A new multi-parallel condition assessment scale for estimating tunnel-induced damage

Laefer, Debra F. ; Conry, B. ; Murphy, D. ; Ceribasi, Seyit (2008-06)

Traditional means to predict tunnel-induced damage for large groups of potentially affected above ground structures has generally focused on creating a settlement trough and estimating subsequent building response limited ...
New possibilities for damage prediction from tunnel subsidence using aerial LiDAR data

Laefer, Debra F. ; Hinks, Tommy ; Carr, Hamish (2010-06)

Computation modelling has not been fully exploited for predicting building damage due to tunnel-induced subsidence, because of the expense and time required to create computational meshes for the vast quantity of buildings ...
Predicted tunnel-induced settlement and damage to Findlaters church with respect to freefield and constructed side considerations

Murphy, J. ; Gaynor, S. ; Laefer, Debra F. (2010-02)

Dublin, Ireland is scheduled to constructing its first metro in 2010, with a pair of tunnels connecting the city center to the airport. This study presents first-order predictions of the anticipated soil settlement and ...
Predicting reinforced concrete frame response to excavation induced settlement

Laefer, Debra F. ; Ceribasi, Seyit ; Long, James H. ; Cording, Edward J. (American Society of Civil Engineering (ASCE), 2009-11)

In many tunneling and excavation projects, free-field vertical ground movements have been used to predict subsidence and empirical limits have been employed to evaluate risk. Validity of such approaches given the reality ...
