The selected design specification can be freely changed during the design process. Access to the specifications type is provided in the Project Settings dialog box. When the specifications are changed, design parameters that are specification-dependent and which have been designated as “automatic” (e.g., load and resistance factors) will be automatically updated to reflect the particular design specifications selected. As a result, it is recommended that when the governing type of specifications is switched, the input data and results be carefully reviewed to understand the full extent of the changes.
The AREMA Specifications are mostly identical to the STND Specifications. We will only point out the differences between those two specifications in this section. Also, any reference to LRFD will generally mean all of the LRFD specifications listed above. If any of the LRFD specs differ, this will be noted.
