| Abstract: |
Anchor channels are a common fastening system for attaching highly loaded base plates of non-structural and structural components to reinforced concrete structures using channel bolts. The reliability and robustness makes this fastening system also popular for seismic applications. An innovative gap filler set was developed to eliminate the gap between the base plate and the channel bolt as well as between the channel bolt and anchor channel, and thus to further improve the seismic performance. Following the introduction of anchor channels and channel bolts in the context of seismic loading, some background information is provided, and qualification as well as design is addressed. Finally, monotonic (static) and cyclic (seismic) tests on channel bolts installed without and with gap filler are presented and discussed to demonstrate the benefits of gap filling. |
