The sequence of strong earthquakes in Canterbury in 2010 to 2011, most notably the devastating Mw 6.2 earthquake on 22 February 2011, the source of which was located within Christchurch, resulted in 185 fatalities and extensive damage to buildings and infrastructure. Liquefaction occurred on several occasions through the…
Lecture Summary There is a growing emphasis on Displacement Based Earthquake Design (DBD) analysis for buildings, retaining walls and bridge structures. DBD is specified as the preferred design method for highway structures in a draft revision of Section 5 of the Bridge Manual (NZ Transport…
More and more, society requires to know the risk which people, property and the environment are exposed to. The role of the geotechnical engineering profession should increasingly be reducing exposure to threats, reducing risk and protecting people. The objective of the 55th Rankine Lecture is…
Ground engineers routinely use simple relationships – rules of thumb – to obtain soil parameters and to design ground works. Some of these have a sound theoretical basis and can be applied generally while some are purely empirical and so should be applied only within…
This paper sets out a simplified approach by which the practical foundation designer can undertake the relevant calculations to satisfy the requirements for deep foundation design in seismic areas. The following matters are dealt with: Design issues that should be addressed; Pile design for axial…
