In this study, basic methodologies and procedures for generation
synthetic time histories in time domain and frequency domain are
summarized. These synthetic time histories are matching Syrian
spectrum and compatible with wide range of buildings m
odels and
soil types according to the seismic parameters of Lattakia city. This
paper will discuss the Selection and scaling criteria of three real
time history records available in strong ground motion databases to
satisfy the Syrian spectrum, and the suitability as input to time
history analysis of civil engineering structures.
