WUF-W1 SPEAKER

Description

KEY FEATURES:

Design Purpose: The WUF-W1 connection is designed to provide a reliable and ductile connection between beams and columns in steel moment frames. It is particularly effective in resisting seismic forces1.

Construction: This connection involves welding the beam flanges directly to the column flange and the beam web to a shear tab that is welded to the column flange1.

Seismic Performance: The WUF-W1 connection is prequalified for use in special moment frames (SMF) and ordinary moment frames (OMF) due to its proven performance in seismic conditions1.

Plastic Hinge Location: The plastic hinge is designed to form at a specific distance from the column face, typically at half the beam depth, ensuring that the inelastic deformation occurs away from the column1.

Welding Requirements: The connection requires complete joint penetration (CJP) groove welds for the beam flanges and fillet welds for the beam web. The welds must meet stringent quality standards to ensure the connection’s performance under seismic loading.

SPECIFICATION:

Applicable Systems: Suitable for use in SMF and OMF2.

Beam Depth: Typically used with beams up to W362.

Material Specifications: Compatible with A572 Grade 50, A992, and A913 Grade 50/S75 steel2.

Welding Details: Requires CJP groove welds for flanges and fillet welds for the web2.

Hinge Location: Plastic hinge forms at a distance of half the beam depth from the column face
