AbstractBangkok is the capital city of the Kingdom of Thailand. Seismological history has been recorded some particular damages to the city and some other area within country. The earthquake responses of Bangkok area in Thailand were analyzed in terms of acceleration and velocity spectra, ~nd maximum surface acceleration. Due to the lack of dynamic soil properties, average relations of shear modulus and damping according to strain proposed by SEED & IDRISS were employed. Due to the absence of the earthquake motion data, the existing earthquake accelerograms from California (Pasadena Earthquake Accelerogram) was scaled to yield suitable rock motion-time histories. The SHAKE program was then employed to analyse the ground motion. Th ~ results are discussed and illustrated with respect to two main parts; i) Characteristic of earthquakes affecting ground motion ii) Evaluation of ground motion during 1983 Bangkok earthquake. With increase in the applied base rock acceleration , the computed ground surface acceleration (As) increase and converge on maximum value of about As=0.3 g. The calculated intensity has large scale compared with the intensity obtained by the earthquake events in Bangkok area during the 1983 Bangkok earthquake .
