Using ambient vibration measurements for risk assessment at an urban scale: from numerical proof of concept to beirut case study (lebanon)

HIGHLIGHTS

• who: Christelle Salameh from the seismic prevention policyThe basic tool is the neural network approach developed in the previous sections, especially the second one based on the structure-to-soil frequency ratio, PGA level and H/V amplitude. In that aim, the required information is an inventory of buildings with their typology and frequencies, together with the measurement of the soil frequencies and of the corresponding A HV amplitudes. For this purpose, buildings located in downtown Beirut were surveyed by Saint Joseph University (USJ) staff within the framework of the LIBRIS ANR project, gathering information on the . . .
