Dr Griffith is a Professor in the School of Civil, Environmental and Mining Engineering at the University of Adelaide where he has been since completing his PhD at the University of California at Berkeley in 1988. He has authored or co-authored 2 book chapters and over 140 refereed papers in the field of earthquake engineering and structural dynamics and has attracted over $4 million competitive funding since 1990 for his research. His professional interests are in the field of earthquake engineering and include training practising engineers to work with Urban Search and Rescue (USAR) teams throughout Australia.
His current research activity is on trying to develop improved methods for seismic assessment of unreinforced brick masonry (URM) buildings and seismic strengthening/retrofit of seismically vulnerable URM buildings. He is also currently involved with specialist consultant work for engineering firms in the field of earthquake engineering, is a member of the joint Australia-New Zealand Standards Earthquake Loading committee, and previously worked as a structural engineer in Berkeley, specialising in the earthquake analysis and design of piping systems in nuclear power plants.

During my 31 years at Adelaide, I have taught subjects to students at all year levels of the BE(Civil) degree course as well as some subjects in the Bachelor of Architecture degree course. I take great pride in my teaching and regard this aspect of university work to be very important. Indeed, I enrolled in and completed the ACUE (as it was then) course for new university lecturers in 1988 long before it was a requirement for newly appointed lecturers. I believe that students consider me to be a very good teacher – as evidenced by the anecdotal feedback I receive from them and from the “scores” I receive from them on the SELTs. For example, only once since 2002 have I received less than 6 out of 7 for their response to “All things considered, how would you rate Dr Griffith’s effectiveness as a university lecturer”.
While my teaching has been primarily in the area of structural engineering, I have also taught Construction and Surveying to our students and regularly assist with the running of group projects in the 1st year introductory subject Engineering Planning and Design.
Significantly, I was invited to give the “Seismic design of masonry buildings” course to the post-graduate students at the European School for the Reduction of Seismic Risk at the University of Pavia in northern Italy, in January 2007. This is a very high honour as the lecturers for all the courses in this programme are international experts from highly regarded universities around the world (see school website: http://www.roseschool.it/index.php?option=com_lecturers&Itemid=84).
Associate Professor Griffith has nearly 20 years research experience in the area of earthquake resistant design and analysis of structures, beginning with his PhD research at the University of California at Berkeley. During this time he has published over 140 refereed papers in this area and attracted over $4 million dollars in competitive research funding in Australia. In the field of earthquake engineering, Dr Griffith has been closely involved with the development of new technologies to improve the seismic resistance of both new and existing structures. His initial work in this field, based on his PhD research, was to demonstrate experimentally and theoretically the feasibility and reliability of seismic isolation as an effective seismic design strategy for a wide range of building heights and earthquake ground motions. His research at the University of Adelaide has focussed on developing methods to prevent earthquake induced damage, including collapse, of unreinforced masonry buildings and non-seismically designed reinforced concrete frames. Recent outcomes and progress in these areas are described below.
His research on masonry walls has led to the development of a displacement-based analysis technique for assessing the earthquake resistance of existing and the design of new masonry walls in vertical bending. Currently he is working with colleagues to extend this innovative design technique to walls subject to bi-axial (two-way) bending. In addition, some of his results from shaking table tests on typical wall connections in masonry buildings have already been incorporated into the Australian Masonry Structures Code in the form of amendments to allow friction to be considered as part of the seismic load path. Two projects that are currently in progress involve (1) establishing deemed-to-comply design guidelines for masonry buildings under 15m tall with respect to earthquake loading; and (2) developing an innovative technique for earthquake strengthening of masonry walls using fibre reinforced polymers in such a way that it does not alter the normal, aesthetic appearance of masonry.
Concrete Frame Research:
Earthquake related research on concrete structures at Adelaide has focussed on the seismic performance of concrete frames whose design is dominated by gravity-load considerations and methods for their seismic upgrade. Experimental research has consisted of shaking table tests of 1/5-scale concrete frame structures, quasi-static cyclic testing of ½-scale concrete frames with and without masonry infill panels, and monotonic static and quasi-static cyclic testing of concrete columns. Non-linear dynamic modelling procedures have now been developed that can accurately model the dynamic behaviour observed during experiments. Current research is focussed on developing practical methods to improve the strength and ductility of such concrete columns and frames using composite plating techniques that fully accounts for the partial-interaction behaviour between the concrete sections and the plates.
