RISA-Tekla Link v10 Released

The release of the RISA-Tekla Link v10 introduces compatibility with Tekla Structures V2020. This update of the link includes the following features as well as other enhancements: Added the ability to align the top of beam elevation using detailing information and cardinal points. Added the ability to round-trip rigid link elements. These improvements are important because RISA-3D defines members by their analytical centerline for the structural analysis and design, while Tekla Structures defines members by their physical alignment for constructability and detailing purposes. Cardinal points are used to properly map member positions when a RISA-3D model is imported into Tekla. Additionally, cardinal points enable the engineer to specify the "true" elevations for member connections and alignment without affecting the structural analysis and design. Another new improvement included in the latest release of the RISA-Tekla Link is the support for rigid links. Rigid links can be used to tie members together, such as in the example of two stacked wide flange beams, modeled with rigid links so that the members act compositely (see image below).

RISA is pleased to announce the release of the latest of RISAConnection v14.0.1. The release of RISAConnection v14.0.1 incorporates the following enhancements and updates: Added conventional configuration checks for shear tab connections with HSS columns. Added the ability to copy connection properties from one connection to another similar connection. Added the ability to Auto 'Collapse All' and 'Expand All' properties when connection input property selected. Added the ability to adjust size of text for 2D connection view and program interface. Improved and expanded bolt prying calculations specifically related to the variable 'p'…

Out of Plane Design Checks on Column Web Connections

The AISC 360-16 (15th edition) has added a new section (see page 9-14 through 9-17) that gives direction on how to check the out-of-plane loading on the webs of wide flange columns which are subject to axial and/or bending loads. This applies to shear tabs, double angles and gusset plates attached to wide flange column webs. RISAConnection v10 now incorporates these changes as required by the code for the following connection types: Shear: Column to Beam Clip Angle (One Side) Shear Column to Beam End Plate Shear Column to Beam Shear Tab Shear Brace: Vertical Diagonal Brace – Gusset to Column Vertical Diagonal Brace – Beam to Column Knee Brace In the case of moment connections, if the plate connects to the column web, there are transverse stiffeners on the opposite side of the column that are required and prevent out of plane bending. If the plate does not connect to the column web, then there is no axial load present in the column web. For each shear and brace connection where the out-of-plane web checks are required, the following limit states are now included: Column Web Punching Shear Column Web Axial Yielding Column Web Flexural Yielding HSS Transverse Plastification…
