Zusammenfassung |
A macroseismic methodology of seismic risk microzonation in a low-rise city
based on the vulnerability of residential buildings is proposed and applied
to Colima city, Mexico. The seismic risk microzonation for Colima consists of
two elements: the mapping of residential blocks according to their
vulnerability level and the calculation of an expert-opinion based damage
probability matrix (DPM) for a given level of earthquake intensity and a
given type of residential block. A specified exposure time to the seismic
risk for this zonation is equal to the interval between two destructive
earthquakes. The damage probability matrices were calculated for three types
of urban buildings and five types of residential blocks in Colima. It was
shown that only 9% of 1409 residential blocks are able to resist to the
Modify Mercalli (MM) intensity VII and VIII earthquakes without significant
damage. The proposed DPM-2007 is in good accordance with the experimental
damage curves based on the macroseismic evaluation of 3332 residential
buildings in Colima that was carried out after the 21 January 2003 intensity
MM VII earthquake. This methodology and the calculated PDM-2007 curves may be
applied also to seismic risk microzonation for many low-rise cities in Latin
America, Asia, and Africa. |
