The present invention relates to a moment-resistant structure, sustainer, and method of construction for deformably resisting episodic loads, particularly those of high intensity. The episodic loads may be due to earthquake, impact, or other intense episodic sources. The structure and sustainer may be in buildings, bridges, or other civil works, land vehicles, watercraft, aircraft, spacecraft, machinery, or other structural systems or apparati. Deformation capacity is enhanced by the use of multiple dissipative zones. Dissipative zones that function in a manner similar to plastic hinges are determined by one or more voids that are located in the web of a sustainer. The one or more voids are of a size, shape, and configuration to assure that the dissipative zones deform inelastically when a critical stress, i.e., a maximum allowable demand, is reached, thereby developing the action of a structural fuse, preventing the occurrence of stress and strain demands sufficient to cause fracture of the connection welds or adjacent heat-affected zones, i.e., preventing the stress and strain demands from exceeding the strength capacity of the connection welds or adjacent heat-affected zones. The sustainers may be removably connected to the remainder of the structure, facilitating their replacement after inelastic deformation. The structure, sustainer, and method of construction may be utilized in new construction and in the rehabilitation of existing construction. Mechanical equipment and utilities may pass through the voids.
