Seismic Design of Steel Chevron and Split‐X Concentrically Braced Frames
1 Introduction Steel concentrically braced frames (CBFs) are commonly used as the lateral-load resisting system in the seismic design of steel buildings. In steel CBFs, the braces are connected to the beams and columns to create a vertical truss transferring lateral loads to the base of the structure. CBFs are designed with Tension–Compression (T/C) or Tension–only (T/O) braces.

Lateral Torsional Buckling Response of Compact I-Shaped Welded Steel Girders
Abstract Recent studies investigating lateral torsional buckling suggest that North American steel design provisions may overestimate the bending resistance of welded girders that buckle laterally in the inelastic range.

A simplified seismic design method for limited-ductility steel multi-tiered concentrically braced frames in moderate seismic regions
Authors: Eshagh Derakhshan Houreh and Ali Imanpour imanpour@ualberta.ca Canadian Journal of Civil Engineering e-First Abstract Résumé References Supplementary Material Abstract Steel multi-tiered concentrically braced frames (MT-CBFs) represent a bracing configuration where two or more concentric bracing panels are stacked between the ground and roof levels in tall single-storey buildings.
Seismic design and response of steel multi-tiered concentrically braced frames in Canada
This article investigates the seismic design and response of steel multi-tiered concentrically braced frames (MT-BFs) in which braces meet at columns between diaphragms. The seismic design provisions of CSA S16-14 are described and illustrated for three-tiered Type MD (moderately ductile) and five-tiered Type LD (limited ductile) braced frames. Analysis methods are proposed to evaluate the in-plane flexural demand on columns.
