Evaluation of structural earthquake damage to buildings in Southwestern B.C. Blanquera, Ardel
Abstract
Seismic risk to the general building inventory is difficult to quantify. Risk analyses study the regional distribution of estimated damage that a building inventory will experience given a level of seismic intensity. This thesis presents a methodology for the evaluation of structural earthquake damage to buildings in Southwestern British Columbia. The steps in the risk analysis i addressed in this methodology are: (1) development of building inventory, (2) selection and application of motion-damage relationships and (3) regional distribution of damage using a geographic information system. Damage is measured as the ratio of dollar loss to replacement cost, or mean damage factor. The seismic hazard is characterized in terms of the Modified Mercalli Intensity. Only damage due to ground shaking hazard is considered. Several motiondamage relationships from prior expert opinion based studies were compared to select appropriate damage functions for use in this methodology. A case study is presented of the City of New Westminster, British Columbia. The seismic risk analyses was performed on a building inventory consisting of approximately 8,000 residential, commercial and industrial buildings. Two separate analyses were performed for comparison. The first uses a structural classification system based on 15 building types and the second is based on 31 building types. The regional distribution of results are aggregated and presented using the geographic information system, Maplnfo®.

Seismic risk to the general building inventory is difficult to quantify. Risk analyses study
the regional distribution of estimated damage that a building inventory will experience given a
level of seismic intensity. This thesis presents a methodology for the evaluation of structural
earthquake damage to buildings in Southwestern British Columbia. The steps in the risk analysis
i
addressed in this methodology are: (1) development of building inventory, (2) selection and
application of motion-damage relationships and (3) regional distribution of damage using a
geographic information system. Damage is measured as the ratio of dollar loss to replacement
cost, or mean damage factor. The seismic hazard is characterized in terms of the Modified
Mercalli Intensity. Only damage due to ground shaking hazard is considered. Several motiondamage
relationships from prior expert opinion based studies were compared to select appropriate
damage functions for use in this methodology.
A case study is presented of the City of New Westminster, British Columbia. The seismic
risk analyses was performed on a building inventory consisting of approximately 8,000
residential, commercial and industrial buildings. Two separate analyses were performed for
comparison. The first uses a structural classification system based on 15 building types and the
second is based on 31 building types. The regional distribution of results are aggregated and
