Taiwan is located in the Circum-Pacific Seismic Zone. The seismic capacity of buildings is relevant for protecting life and property. It is also an important topic for earthquake engineering research. In addition to the seismic capacity of building structures, earthquakes have an impact on nonstructural components, which will affect the operation of safety systems in buildings. For example, fire protection sprinkler piping systems in hospitals are very important and can reduce the incidence of fire after occurrence of an earthquake if their integrity is maintained. The standard NFPA13 developed seismic specifications for fire protection sprinkler piping systems. Among the specifications, the design of the seismic bracing was described in detail, but there were no detailed provisions for attachments between the seismic bracing and pipeline or building. Thus, the National Center for Research on Earthquake Engineering implemented research on the system in accordance with NFPA13. The study showed the weak point occurred in the attachment rather than the seismic bracing, and it reduced the seismic capacity. In this study, the deformation and the failure modes of a commercially available attachment were examined using tests and numerical analyses. |
