Hollow Section Connection Design:: Input Data

The document provides input data and calculations for designing a hollow section connection. It includes load values, material properties, section dimensions, and angles. The output shows the connection passes checks for chord plastification and bracing punching shear. Calculations determine capacity values using functions that consider parameters like load ratio, slenderness, and angle. The connection design meets all criteria and the provided references were used for aspects not covered by code.
