A Statistical Study of Some Design Concepts in Earthquake Engineering
The results of a study of techniques for improving the safety of seismic structures are presented. In particular, the effect of passive motion reducing devices on seismic structures was investigated. A Monte Carlo technique was applied to analog simulations of the random earthquake and corresponding response processes. It was found that the following passive devices can be quite effective in reducing seismic structural response: additional damping provided at the first floor only, an untuned damper attached to the roof, a vibration absorber attached to the roof, and a vibration isolator placed between the ground and the foundation. Combinations of devices listed were also investigated. On the basis of structural safety, these modified systems are ranked in the order of their efficiency as follows: isolator, isolator-absorber, absorber-damper, absorber, the damper. (Author)
