About This Project
The Weld Connection Calculator features two comprehensive analysis modes following NSCP 2015 Section 510 and Besavilla's Simplified Steel Design methodology using the Allowable Stress Design (ASD) approach.
Part I: Tensile Load Analysis evaluates angle steel connections by comparing three critical limit states—Gross Area Yielding, Net Area Rupture, and Block Shear—to determine the maximum safe tensile force with governing failure mode identification.
Part II: Balanced Weld Group Analysis offers dual sub-modes: Check Design calculates connection capacity from given weld lengths, while Find Required Length determines minimum weld length needed for applied loads. Both modes include automatic weld size validation and failure mode analysis.
Key Features
- Part I: Three limit states analysis (Gross Area, Net Area, Block Shear)
- Part II: Check Design mode for capacity evaluation
- Part II: Find Required Length mode for weld sizing
- Automatic weld size validation per NSCP 2015 Table 510-4
- Real-time calculations with governing failure mode identification
