Loads can be categorized as one of 12 types:
- Live. Superimposed and modeled entirely by the user.
- Dead. Superimposed by the user. This type does not include the self-weight.
- Material. Includes the self-weight. This factor may be increased by applying a uniform ponding load to take into account non-uniform concrete distribution, and may also be scaled up by a wet weight factor for concrete.
- Construction Live. Superimposed live loads during construction conditions.
- Construction Dead. Superimposed dead loads during construction, not including self-weight.
- Other miscellaneous types: Wind, Roof Live, Seismic, Snow, Temperature, Accidental, and Unknown.
By default, load factors from ASCE 7-10, Minimum Design Loads for Buildings and Other Structures, Strength Design (2.3.2) are used in the design and analysis process, but arbitrary combinations can be viewed as well. The following load combinations are considered for composite member design:
- 1.4DL
- 1.2DL + 1.6LL
Where:
DL indicates Dead, Material, and Construction Dead load types
LL indicates Live and Construction Live load types.
All other load types are displayed, but are not included in the beam design.
