Connection Design Clip Angle Welded to Supporting Member

Connection Design

Clip Angle – Welded to Supporting Member – Alternative width for supporting wide flange members. – Allows the user to define an angle size for a range of flange widths. – This can be used with Single or Double clip angles.

Reinforcement Plates

Rod Bracing • Vertical braces as rods with clevis and turnbuckles. • Connections are designed and design calculations will be provided. • Round bar is now part of the material file. They will be found in the new default material files, but will need to be added to any job brought up from a previous version. • New steel grades setup screen for the Turnbuckle/Clevis/Pin • Member Detailing/Fabrication Options>Tension Only Braces, allows the user to define setup values for the Rod Bracing.

Moment Bent Plates • Wide Flange Beam to Wide Flange Column • Welded or bolted moment

Horizontal and Vertical Brace • HSS Horizontal Brace Paddle Plates (Double Shear) • Wtee Vertical Brace – Copped Flange Connection • Double Angle Vertical Brace – Near side or far side • 20 degree Horizontal Brace – Limitation taken away

Base Plates Extension with Stiffeners – Extended stiffeners under baseplates when a column frames to a beam with narrow flanges. – Will provide either one or two stiffeners depending on the loading. – Setup in Standard Fabricator Connections to define size and clearance. – Plate overhang tolerance specifies how much the baseplate must overhang the beam flange before automatically providing ext. plates

Plate Schedule Information – All base plate information can now be found in the member or connection edit. – Weld size and location can be changed. – Extension information is accessible.

Varying Hole Spacing – Can be used on clip angle, shear, end plate and bent plate connections. – Design Calculations will reflect the spacing, including the bolt center of gravity checks. – Comma separated (3, 3, 4) – @ symbol (3@3. 5) – Combination of comma separated and @ (3@3, 4) – Adding more spaces will update the rows of bolts
