exist in the development of vulnerability models. Currently these models examine the
potential for damage at various levels of earthquake ground shaking. They need to be extended both in depth
and breadth. More vulnerability
models need to identify specific modes of failure for each component. They also need to identify time and
cost to repair that particular mode of failure for use in emergency
management, which will help optimize the emergency response process.
is often about choices and alternative choices. Emergency management software can
identify alternatives that can be implemented during the reconstruction
process that could reduce losses.
A work around that has been relied on in the past is the use of cotton
rope to tie electric components together. This alternative to complete
replacement, did well until the first rain came along and the rope got wet,
stretched and caused a fault.
