This report describes the observations and preliminary assessments of the members of the Reconnaissance Team of the New Zealand National Society for Earthquake Engineering which visited Kobe, Japan and the surrounding areas following the Hyogo-ken Nanbu earthquake of 17 January 1995. The report covers aspects of the effects of the earthquake on the ground, lifelines, buildings, bridges and other structures, and the community. Lessons for New Zealand are discussed.
This paper describes the restoration of the rail and road routes which were seriously damaged in the Great Hanshin Earthquake of 17 January 1995. It is based on observations and data provided during a visit to Kobe, Japan in July 1995, 6 months after the earthquake.
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 development of a common Earthquake Loading Standard for Australia and New Zealand which has the potential for most countries in SE Asia is discussed in this paper. An historical perspective of earthquake loading standards in the two countries is introduced for background. In addition, two internationally recognised standards, Uniform Building Code (UBC) and Eurocode 8, covering earthquake loadings for areas of both low and high seismicity are presented. A seismic zoning scheme similar to the UBC approach is tentatively suggested for describing the seismic hazard of Australia and New Zealand. It is suggested that the requirements for design and detailing could vary from nominal tying together to capacity design procedures for the lowest and highest seismic zones respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
