SR177 Base isolation of low-rise buildings using synthetic liners (2007)

This report presents the results of a preliminary investigation into the practicality of base isolating low-rise buildings by placing synthetic liners beneath the foundation slab. The slip coefficients as a function of axial load, number of cycles and velocity were determined for various liners with both standard and modified surfaces. The effects of grit on the surface and lap joints between sheets were examined.

This is the second study report prepared during research into base isolation of low-rise buildings. There were also four BRANZ unpublished reports on this subject. However, the key findings from these unpublished reports were reproduced in the first study report (SR156) .
