Nominal Strength – Baseline values representing the unfactored loads as defined by AISI S100-16 standards.
LRFD Design Strength – Factored loads calculated in accordance with Load and Resistance Factor Design (LRFD) principles, commonly used for strength-based design. In this document, LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
Service Loads – Unfactored loads used for evaluating serviceability conditions such as deflection, vibration, and crack control. In this document, the Service Load Limit for connectors are the load at 1/8 in. deflection.
These supplemental values are particularly useful for projects utilizing LRFD, where understanding service-level performance is critical. They allow designers to identify conditions where serviceability may govern over strength requirements.
Additionally, this document can be referenced for blast load considerations on Department of Defense (DoD) projects, where specialized load cases must be incorporated into the design process.
By providing comprehensive sets of load data, these charts serve as a practical resource for engineers to ensure compliance with multiple design criteria and project-specific requirements.
