Improving Seismic Design Efficiency of Petrochemical Facilities
Publication: Practice Periodical on Structural Design and Construction

Abstract
This research studied the seismic performance of equipment support structures with knee-braced moment-resisting frames in petrochemical facility construction. Frame performances were evaluated using the structural stiffness, strength, and ductility. It was found that frame stiffness increases when the magnitude and slope of knee braces increases. For practical purposes, it is suggested that the ratio be kept at 1 and less than 0.25 times the beam length. It was also observed that the maximum member forces in traditional special moment-resisting frames are shifted from the critical beam-column joints to the beam-knee brace intersections, which greatly reduces the risk of brittle fracture at those regions and significantly enhances the structural ductility.
