Risa Connection - Software

Instead of manually typing in the ultimate loads for a specific beam-column intersection, you right-click the joint in RISA-3D and select "Send to RISAConnection." The software imports:

RISAConnection is a specialized structural engineering software used for the comprehensive design and optimization of hot-rolled steel connections

. As part of the wider RISA product suite, it allows engineers to perform complex calculations within a 3D modeling environment, ensuring code compliance and structural integrity. Core Functionality Connection Types

: The software supports nearly all standard steel connections, including: Shear Connections : Clip angle, end plate, and fin plate. Moment Connections : Flange plate, end plate, and direct weld. Brace Connections : Vertical and horizontal bracing using gusset plates. Splice Connections : Column and beam splices. Integration : It integrates directly with risa connection software

, allowing for the automatic transfer of member sizes and seismic/gravity loads. Code Compliance : Supports the latest AISC (American Institute of Steel Construction) CSA (Canadian Standards Association) design codes. Key Technical Features 3D Visualization

: Features a highly interactive interface where users can rotate models 360 raised to the composed with power

to inspect components like bolts, welds, and plates from any angle. Real-time Calculations

: As you modify geometry or loading, the software provides instantaneous feedback on whether the connection passes or fails code checks. Customizable Reporting Instead of manually typing in the ultimate loads

: Generates detailed, step-by-step calculation reports that include specific code references and sketches for easy verification and submittal. Practical Applications

RISAConnection is commonly used for the design of large-scale infrastructure and industrial projects, such as: Skyscrapers and airports. Petrochemical facilities and bridges. Stadiums and specialized towers. Educational Access

Students can often access RISA products for free through the RISA Education program

A standout feature of RISAConnection is its expandable limit state reporting, which provides engineers with full transparency into every calculation performed. Unlike "black box" software, it allows you to drill down into the specific formulas and code references used for each check, ensuring complete verification according to AISC or CSA standards. Key Features of RISAConnection

RISA Connection covers the vast majority of standard steel construction scenarios:

Many structural engineers ask, "Why can't I just design connections by hand or in a spreadsheet?" For simple single-plate shear tabs, you can. However, modern buildings involved complex load interaction. Consider a moment connection at a beam-column joint. A hand calc might take two hours to check the flange welds, bolt group tension, panel zone shear, and web crippling. RISA connection software does this in 30 seconds.

Furthermore, mistakes in hand calcs are common. Engineers often forget to check:

RISAConnection automates these tedious, error-prone checks, ensuring that the connection isn't just strong—it is code-compliant down to the last weld size.

While known for hot-rolled steel, RISA also offers modules for cold-formed steel (CFS) connections—screws, clinches, and powder-actuated fasteners. This is vital for light-gauge commercial and residential multifamily projects.
