Abstract：This is paper investigates acceleration response spectrum of long span floor under human walking loads. Three hundred and twenty experimental measurements of walking load curves have been applied to a long span floor to obtain the 10-second root-mean-square acceleration response spectrum, based on which a simplified mathematical model has been suggested for frequency range of 3-20Hz. The effect of several computational parameters including higher vibration modes, boundary condition, floor span, stride length and damping ratio on the spectrum has been studied and corresponding correction measure has been suggested. Detailed implementation procedure of the suggested response spectrum has been presented. The feasibility and applicability of the suggested spectrum has been validated by comparing the prediction results with field measurements of an existing long span floor. ;
