5950-1

The Eaton 5950-1 is a specialized software module for structural engineering, specifically designed to conduct steel design checks in accordance with the BS 5950-1:2005 standard. This tool is crucial for engineers needing to verify the integrity and performance of steel members under various load conditions.

The module assumes all input cases are at the ultimate limit state (ULS), meaning member forces are fully factored. Non-ULS cases, such as unfactored wind loads, will be treated as ULS, potentially leading to non-conservative utilizations. The software provides detailed checks, including local capacity assessments at each end of subs-spans, considering moments and forces applied to the member's section. It supports plastic and compact section classifications.

Specific features include the management of the maximum plastic/elastic ratio to limit plasticity effects at the serviceability limit state (SLS). The checker enforces limits of 1.2 for simply supported members and cantilevers, and 1.5 for members with moment continuity, aligning with BS5950-1:2000 4.2.5.1. For single angle struts, the software addresses axial buckling considerations by referencing A-A, B-B, and V-V axes, with V-V being the minor principal axis. It also interprets connection restraints, such as those from bolt groups, to accurately model member behavior and local capacity checks, referencing clauses like 4.7.10.2 and 4.6.3.1.
