AISC 360 – Shear plate Znet calculation for unequal edge distance configurations: A new equation was implemented to calculate the plastic net section modulus Znet of shear plates for cases where the edge distance Lev differs from (s/2), making AISC Manual Equations 15-4 and 15-5 not directly applicable. The implementation follows the methodology presented in the AISC Design Examples Manual v15 for single-plate shear connections, improving accuracy for nonstandard edge distance configurations.

AISC 341 – Reinforcement area not included for bolted HSS brace rupture checks: The reinforcement area for HSS braces bolted to gusset plates is now properly included in the seismic branch tensile rupture calculations, increasing the effective net area used for brace strength evaluation and updating the brace and gusset report sections accordingly.

AISC 360 – Gusset beam stub splice connection using incorrect member properties: The stub-to-support design logic for gusset connections with beam stub and splice configurations was corrected to use the geometric and section properties of the actual stub member instead of incorrectly referencing the beam properties, improving the consistency and accuracy of the generated connection design results.

AISC 360 – Incorrect Qf stress evaluation for rotated tubular chord sections: The stress evaluation for plastification reduction factor (Q_f) calculations was corrected for rotated chord sections in tubular truss connections by properly transferring the in-plane moment component into the design calculations, ensuring that chord face stresses and plastification checks are evaluated using the correct stress state.

AISC 360 – Incorrect K-joint classification in tubular truss connections: A correction was implemented in the tubular joint classification logic for K-connections where a parameter related to branch verticality evaluation in two-branch joint configurations was producing incorrect classification results in some cases. The revised implementation now provides the correct joint classification behavior.

AS 4100 – Anchor bolt section modulus and ultimate strength corrections: The AS 4100 anchor bolt implementation was corrected by updating the section modulus formulation and replacing the incorrect use of Fy with Fu where applicable in the bolt shear strength calculations, aligning the Australian code behavior with specification intent and maintaining consistency with equivalent implementations in other international design codes such as EN.

RAM Connection is the ideal solution when structural engineers or designers need to check a specific connection, design a single connection for multiple joints, or optimize each connection in a structure. Analyze, design, and verify structural steel connections, all with comprehensive calculations, including seismic compliance. RAM Connection can check or design connections in seconds. Whether you design connections or need to check connections designed by the shop, RAM Connection is the software for you. In just one low-cost package, you get for steel frame connections the AISC ASD and LRFD, AS 4100-1998, BS5950-1, CSA S16-14, EN1993-EC3, GB50017 and IS800 connection design and optimization for shear and moment connections, braced frame connections, splices, and horizontal bracing connections. For truss connections you get the tubular connections design according to the AISC and the HSS Connection Design Manual. Through its seamless integration with the RAM Structural System, RAM Elements, and STAAD.Pro, RAM Connection raises the bar to a new level of productivity. All data regarding member sizes, joint geometry, and forces are transferred directly from either the RAM Structural System, RAM Elements, or STAAD.Pro to RAM Connection.
