A structural frame where rigid beam-to-column connections resist wind and earthquake forces through bending.
A lateral force-resisting structural system in which beams and columns are connected with moment connections that resist lateral loads through bending of the members. Moment frames allow open floor plans without diagonal bracing or solid shear walls. They are classified as ordinary, intermediate, or special depending on their ductility and seismic detailing requirements.
A special moment frame along the building perimeter provides seismic resistance while maintaining large window openings.
