Can Staggered Trusses Be Used in Seismic Zones? [E9a]

While staggered trusses have been very successful in low- and medium-seismic designs, there is debate about whether they offer adequate ductility and load transfer options in high-seismic areas. But recent improvements in staggered truss design, including different Vierendeel truss openings and the addition of interior posts, columns, and braces, may make them suitable for high seismic area. This presentation will examine current staggered truss design practices and newly proposed improvements, as well as presenting several case studies.
