Ground response spectra at surface for Mayagüez considering in-situ soil dynamic properties
One dimensional ground response analyses was performed at fifteen sites in Mayagüez Puerto Rico to study their seismic response for the development of response spectra at the surface. Field experiments using the Spectral ...
A variable damping semiactive device for control of the seismic response of buildings
This dissertation proposes a new semiactive device, composed of two fixedorifice viscous fluid dampers installed in the form of V whose top ends are attached to the upper floor and their lower ends to a point that can move ...
Dynamic properties and seismic response of the cable structures and towers of the Arecibo Observatory
This investigation was requested by the staff of the Arecibo Observatory to determine whether the towers and cables that support the suspended platform are capable of resisting a maximum-credible earthquake in the elastic ...
