Cable-stayed and suspended post-tensioned solutions for precast concrete frames: the Brooklyn system (2004)
AuthorsPampanin, S., Pagani, C., Zambelli, S.show all
Alternative solutions for precast concrete buildings have been recently developed under the U.S. PRESSS program and successfully adopted with practical applications in seismic regions worldwide. Jointed ductile “dry” connections, obtained through unbonded post-tensioning techniques, have been proved to provide extremely efficient and damage-resistant systems for the next generation of buildings. In this contribution, an extension of these emerging solutions for gravity-load-dominated frame buildings is presented, being named “Brooklyn” system for the peculiarity of incorporating the structural efficiency of a cable-stayed or suspended bridge systems within a multi-storey buildings. An overview of the conceptual definition, development, experimental validations on six full-scale one-storey frame systems will be given, including a description of the up-to-date practical applications on a series of buildings in regions of low seismicity. Proper modifications and validations are under development to accommodate high seismic demand.
