Seismic Behavior and Design of Gusset Plates. Gusset plates are also used in connections of steel trusses. After presenting the summary of behavior a chapter is devoted to the discussion of provisions in the current design codes that are relevant to the seismic design of gusset plates.

The paper first reviews the existing design methods for proportioning gusset plates under monotonic loading as well as under seismic loading. In such frames damage of the gusset plate under earthquake load is one of the most important subjects. Seismic Detailing of Gusset Plates for Special Concentrically Braced Frames.

Normally compared to axial load and shear force bending moments in these base plates are small and ignored in design. Concentrically braced steel frames CBFs are a practical and economical structural system for many applications. Performance and Behavior of Gusset Plate Connections.

Variations of the AISC Uniform Force Method are used for the design of SCBF gusset plate connections but their seismic behavior is not well understood and may not meet expectations. Gusset plates are used in steel building structures to connect the bracing members to the beams or columns. And examines seismic design and building materials.

As a high-performance hysteretic damper buckling-restrained braces BRBs can significantly improve the seismic behavior of engineering structures and protect the main building components from damage. Design and detailing recommendations were also made for the corner gusset plate connection region in BRBFs. The effective width is calculated by assuming the stress spreads through the.

One of the first studies on the gusset plate was performed by Whitmore. Gusset plates have been the subject of major research and engineering studies for the last several years especially because of the interest in the profession for using braced frames for seismic as well as non-seismic construction. The behavior and design of gusset plate connections are reviewed and summarized.

AISC Seismic Design Manual AISC 2012 Ductile Design of Steel Structures Bruneau et al.

In this study the one-piece gusset plate is proposed to be used in the bracing nodes where two braces associated with two sequential adjacent stories of a similar bay intersect each other at the beam-to-column joints in work point WP such as SCBFs with X-braced and split X-braced configurations Fig. It uses k05 when the plate is supported along two edges I have seen k12 when supported along only one edge. In the early tests of gusset plates Rust 1938 before the strain gages were used in structural engineering tests instead of steel plates gusset plates made of polished Bakelite were used.

These base plates are primarily subjected to axial load of downward compression and uplift in combination with shear force. Seismic Behavior and Design of Gusset Plates by Abolhassan Astaneh-Asl This report presents information and tips on seismic behavior and design of gusset plates used in steel concentrically braced frames. Brace buckling places significant force and deformation demands on the brace-beam-column gusset plate connections.

After presenting the summary of behavior a chapter is devoted to the discussion of provisions in the current design codes that are relevant to the seismic design of gusset plates. However the complex BRB-to-reinforced concrete RC member connection is not conducive to the development of BRBs in RC frames and the frame action. Current Design Practice In design gusset plates are treated as rectangular axially-loaded members with a cross section Lw t where Lw is the effective width and t is the plate thickness.

Based on the experimental and analytical findings design and detailing recommendations were developed for the connection at the brace splice point in the single-story X-configured system.
