Real-time data coupling for hybrid testing in a geotechnical centrifuge (2018)
Journal Article
Idinyang, S., Franza, A., Heron, C. M., & Marshall, A. M. (in press). Real-time data coupling for hybrid testing in a geotechnical centrifuge. International Journal of Physical Modelling in Geotechnics, doi:10.1680/jphmg.17.00063. ISSN 1346-213X

Geotechnical centrifuge models necessarily involve simplifications compared to the full-scale scenario under investigation. In particular, structural systems (e.g. buildings or foundations) generally can’t be replicated such that complex full-scale c... Read More

Calibration of strain gauged square tunnels for centrifuge testing (2016)
Journal Article
Tsinidis, G., Heron, C., Madabhushi, G., & Pitilakis, K. (in press). Calibration of strain gauged square tunnels for centrifuge testing. Geotechnical and Geological Engineering, 34(3), doi:10.1007/s10706-016-0015-9. ISSN 0960-3182

A series of dynamic centrifuge tests were conducted on square aluminum model tunnels embedded in dry sand. The tests were carried out at the Schofield Centre of the Cambridge University Engineering Department, aiming to investigate the dynamic respon... Read More

A new macro-element model encapsulating the dynamic moment-rotation behaviour of raft foundations (2015)
Journal Article
Heron, C., Haigh, S., & Madabhushi, S. (2015). A new macro-element model encapsulating the dynamic moment-rotation behaviour of raft foundations. Géotechnique, 65(5), doi:10.1680/geot.SIP.15.P.020. ISSN 0016-8505

The interaction of shallow foundations with the underlying soil during dynamic loading can have both positive and negative effects on the behaviour of the superstructure. Although the negative impacts are generally considered within design codes, sel... Read More

Dynamic response of flexible square tunnels: centrifuge testing and validation of existing design methodologies (2015)
Journal Article

A series of dynamic centrifuge tests were performed on a flexible aluminium square tunnel model embedded in Hostun dry sand. The tests were carried out at the centrifuge facility of the University of Cambridge in order to further improve knowledge re... Read More

Susceptibility of shallow foundation to rocking and sliding movements during seismic loading (2014)
Book
Heron, C., Haigh, S., & Madabhushi, G. (2014). Susceptibility of shallow foundation to rocking and sliding movements during seismic loading. In Seismic evaluation and rehabilitation of structuresSpringer. doi:10.1007/978-3-319-00458-7_23

Current design codes prevent the rocking and sliding of shallow foundations during seismic loading despite much research indicating the beneficial nature of allowing such movements. The primary benefit is the partial isolation of the structure from t... Read More
