Set Up

At the request of the Earthquake and War Damage Commission, the New Zealand National Society for Earthquake Engineering set up a study group to determine the maximum probable loss the Commission may suffer by way of claims resulting from a large earthquake with its epicentre near Wellington. The study group's task was to determine the order of cost of physical damage to buildings and their contents which could credibly be expected to result from large earthquake attack. Seismic loss information for New Zealand conditions is minimal and it was therefore necessary to critically review published overseas data. Where appropriate, adjustments were made to accommodate New Zealand conditions. Loss information was compiled as the ratio of damage cost to building value and varied with felt earthquake intensity as well as with type of building construction. The total value and structural classification of the building stock in the affected area was compiled and entered on a computer. A program was set up to enable loss calculations to be carried out for the appropriate building classification and for the relevant earthquake intensities. From this the total loss was calculated. The results of the study expressed as monetary loss are confidential to the Earthquake and War Damage Commission. In this paper, therefore, results are not presented in absolute dollar terms, but are given as relative values.

In 1974 the Management Committee of the Society authorised the setting up of an earthquake reconnaissance team scheme, whereby a team of suitably experienced observers would be quickly transported to the scene of a damaging earthquake. A sub-committee under Mr. J, P. Rollings was formed and a detailed brief for the scheme was prepared and subsequently adopted by the Management Committee. Following advertisements in the Bulletin and the New Zealand Engineering, a pool of over 35 suitable observers has been formed. Most of the pool are practising civil and structural engineers though a number of specialists, including three architects, have been included. The scheme is now fully operational. At present the team
 organiser is Mr. J. P. Hcllings (Wellington) and his deputy is
Mr. N. D. Bardie (Christchurch). Mr. Rollings is also authorised, 
together with the President, to approve a reconnaissance. It is
intended that all pool members will be issued an Engineering Reconnaissance Manual containing information on the administration and aims of the scheme, the action to be taken following a damaging earthquake and a detailed engineering reconnaissance field guide. The following brief is reproduced from the manual; Section One outlines the aims and administration of the scheme and Section Two, procedures to initiate a reconnaissance. These sections together with a budget sufficient to allow reconnaissance of a large earthquake, have been approved by the Management Committee.

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.

In the fields of earthquake engineering and seismic risk reduction the term “physical vulnerability” defines the component that translates the relationship between seismic shaking intensity, dynamic structural uake damage and loss assessment discipline in the early 1980s, which aimed at predicting the consequences of earthquake shaking for an individual building or a portfolio of buildings. In general, physical vulnerability has become one of the main key components used as model input data by agencies when developinresponse (physical damage), and cost of repair for a particular class of buildings or infrastructure facilities. The concept of physical vulnerability started with the development of the earthqg prevention and mitigation actions, code provisions, and guidelines. The same may apply to insurance and reinsurance industry in developing catastrophe models (also known as CAT models). Since the late 1990s, a blossoming of methodologies and procedures can be observed, which range from empirical to basic and more advanced analytical, implemented for modelling and measuring physical vulnerability. These methods use approaches that differ in terms of level of complexity, calculation efforts (in evaluating the seismic demand-to-structural response and damage analysis) and modelling assumptions adopted in the development process. At this stage, one of the challenges that is often encountered is that some of these assumptions may highly affect the reliability and accuracy of the resulted physical vulnerability models in a negative way, hence introducing important uncertainties in estimating and predicting the inherent risk (i.e., estimated damage and losses). Other challenges that are commonly encountered when developing physical vulnerability models are the paucity of exposure information and the lack of knowledge due to either technical or nontechnical problems, such as inventory data that would allow for accurate building stock modeling, or economic data that would allow for a better conversion from damage to monetary losses. Hence, these physical vulnerability models will carry different types of intrinsic uncertainties of both aleatory and epistemic character. To come up with appropriate predictions on expected damage and losses of an individual asset (e.g., a building) or a class of assets (e.g., a building typology class, a group of buildings), reliable physical vulnerability models have to be generated considering all these peculiarities and the associated intrinsic uncertainties at each stage of the development process.

The Management Committee of the New Zealand National Society for Earthquake Engineering have for some time planned the formation of a Seismic Design Committee.
 It is the intention that this Committee would offer assistance to Local Authorities and to designers, for designs of structures and other developments in seismic engineering which border on present knowledge or which are not covered in accepted codes or texts. The Committee may also assist in providing interpretation of code requirements both to overall concepts and to matters of detail.

Progress on developments in the seismic design procedures for bridges in New Zealand is outlined. The current approach has evolved from the recommendations of a study group of the New Zealand National Society for Earthquake Engineering which was published in 1980. Research and development into the determination of the design seismic force and ductility demand, the capacity design approach, the detailing of bridge columns for adequate ductility, and the design approach using seismic isolation are discussed. More recent developments in New Zealand involving the assessment and retrofit of older bridge structures are also discussed and likely activities and needs of the next decade are suggested.

Evaluation Approach

Unreinforced Masonry (URM) structures, such as historic buildings, traditional buildings and ordinary buildings, exist all over the world and constitute a relevant part of the cultural heritage of humanity. Their protection against earthquakes is a topic of great concern among the earthquake engineering research community. This concern mainly arises from the strong damage or complete loss suffered by these types of structures when subjected to earthquake and also from the need and interest to preserve them as a built heritage. This paper initially presents a methodology for assessing the seismic vulnerability of URM buildings based on vulnerability index evaluation approach. Moreover, this paper presents the correlation between vulnerability index and Macroseismic method to estimate the physical damage in relationship with seismic intensity. Finally, presents implementation of the methodology to construct vulnerability curves, fragility curves and estimate losses.
