Partially restrained
WebPartially restrained composite connections (PR-CC) are partial strength connections that can be used to resist moments induced by live, wind, and earthquake loads in low and moderate height unbraced frames. WebMoment resisting connections are used in multi-storey un-braced buildings and in single-storey portal frame buildings. Connections in multi-storey frames are most likely to be bolted, full depth end plate connections or extended end plate connections. Where a deeper connection is required to provide a larger lever-arm for the bolts, a haunched ...
