Description
The framework of screening techniques for clarifying seismic vulnerability of buried telecommunication pipes was proposed. In the 1st screening, seismic vulnerability of targeted pipes is ranked by four classes for seismic retrofit by using the modification factors showing the relations among damage ratios from the type of pipes, the span length and the microtopography: the highest, higher, moderate, and less priority classes. In the 2nd screening, seismic damage functions are applied to rank up the priority classes for checking the risks of failures of pipes exposed by higher seismic intensity levels. Case studies for the check of the validity of proposed screening techniques by applying observed damage data were shown.
