scholarly journals Review of current earthquake engineering research in New Zealand

Author(s):  
P. J. Moss

Research currently being undertaken in Government Departments, Research organisations, and the Civil Engineering Departments in the two University Schools of Engineering is outlined. The research is summarised under the headings of Seismology, Engineering Seismology, Geotechnical Engineering, and Structural Analysis and Design.

The time is ripe for a review of directions in which earthquake engineering research is, or should be, heading. Half a century has elapsed since New Zealand suffered a serious earthquake in an urban area - during that time, immense changes have developed in both the form and complexity of structures and services. Researchers are tending to think more and more about less and less in their respective encapsulated environments. Are we getting to the stage where aspects of the problem are being well researched but their interdependence is being lost sight of? Or are we even missing important wider aspects? A need encompassing all topics
is the matter of keeping abreast of developments being done elsewhere. In this issue, we commence a series of general articles. These are intended primarily as a stimulus for comment.

Reconnaissance surveys of building and infrastructure damage related to geotechnical engineering aspects were conducted four to six weeks after the 26 December 2004 earthquake and five weeks after the 28 March 2005 earthquake. These surveys identified many instances of building collapse and infrastructure damage that were probably caused by strong ground shaking and/or liquefaction-induced foundation or embankment failures. The survey results suggest the need for earthquake engineering research that identifies likely future earthquakes and their ground motion characteristics. Because of the observed variation in the level of damage, a seismic microzonation study should be performed to identify the spatial variability of strong ground shaking for the purpose of reconstruction and future planning of cities in Nangroe Aceh Darrusalam Province and Nias Island.

The workshop was held in Tokyo immediately
 prior to 9th World Conference on Earthquake 
Engineering. Two previous workshops have
been held in 1984 and 1986 both with an 
emphasis on seismic building design and 
construction practices. New Zealand and
 China were invited to participate in the
 3rd Workshop which was attended by 17 U.S. 
and 23 Japanese representatives. I was
 privileged to attend the third workshop 
which was organised by the Japan Structural
 Consultants Association. 21 papers were
 presented covering building seismic analysis and design, and comparison of design codes and practices. The conference concluded with a working session which allowed a useful exchange of information. In the notes below I have summarized several items of particular interest to New Zealand practitioners.

The Papua and New Guinea Institute of Higher Technical Education enrolled its first students in 1967 and moved to Lae at the beginning of 1968. An active building programme is underway. At the suggestion of Professor J.H. Lavery, University of Queensland, the first project undertaken by the writer on taking up his appointment in February 1968 was research on earthquake engineering problems. Two accelerographs were purchased from New Zealand and installed on the campus in November, 1968.

Most earthquake engineering research projects are concerned with the analysis and design of high-rise buildings. Comparisons of
actual earthquake forces with pseudo-static design forces recommended
by various building codes indicate that in actual earthquakes the forces in low-rise buildings can be up to three to five times the pseudo-static design forces. This paper is concerned with evaluating and comparing the earthquake response of low-rise buildings calculated using local response spectra and real time-histories with various Building Code Recommendations. It is shown that Building Code Recommendations underestimate the
structural response.

On 13 May 1990, an earthquake of magnitude 6.7 occurred near Dannevirke and caused damage both there and in the surrounding area. This report presents the observations of a two person reconnaissance team from the New Zealand National Society for Earthquake Engineering together with details provided by the Engineering Seismology Section of the Institute of Geological and Nuclear Sciences (formerly part of the DSIR).
