Abstract:

The design for the Anaheim Arena roof evolved in response to the strict requirements for a structure in a seismic zone 4 location. The support of the 329 ft. (100 m) by 444 ft. (135 m) arena roof was detailed to provide ductility and inelastic energy dissipation capacity as well as to minimize the seismic forces transmitted to the supporting concrete superstructure below. To meet these requirements the final system incorporated a staged erection procedure which made the use of flexible support columns possible.
