| Abstract: | The models currently used in the seismic evaluation of important projects, microzoning and seismic zonation are all for site.
Although seismic hazard analysis have been done for many sites in seismic zonation and microzoning, relationship among sites
is not considered in the final results. Studies show that it is impossible to get total hazard for specific area from the
results of the hazard analysis of sites. So, when we consider the total seismic hazard of a specific spatial distributed system,
methods for site are not enough. Author discussed the relation and the difference between system hazard and segments hazard
which form the system and proposed a seismic hazard analysis model taking spatial linear distributed series and parallel system
as an example. In aseismic design and earthquake disaster prevention decision, not only the seismic hazard of segments of
the system but also the total seismic hazard of the system should be considered.
