The permanent or dead loads acting on the bridge are input either as DL/ADL on Precast or DL/ADL on Composite. Apart from these, Precast/Prestressed Girder also allows users to input diaphragm loads at various locations along the span of the beam.

DL/ADL on Precast can be input either as Line Loads or Point Loads. These loads are introduced before the topping is added and are, therefore, resisted by the precast section only. The loads specified are for each of the beams that are in the span under consideration. Examples of this kind of load typically include loads due to the weight of stay-in-place forms. If the user specifies the dimensions of the haunch under the Topping Data, its weight will be automatically calculated by the program and need not be included here.

DL/ADL on Composite can be modeled either as Line, Point or Area Loads. These loads are introduced after the topping has been added and hardened and are, therefore, resisted by the precast section acting compositely with the topping. The specified loads are applied to the overall width of the bridge for the span under consideration. In the case where the user specifies an Area Load and a width over which the load is applied, Precast/Prestressed Girder multiplies the two values together and internally analyzes it as a Line Load acting on the continuous beam model. The resulting moments and shears are then distributed to each beam based on the tributary fraction values. Examples of this kind of load typically include loads due to future wearing surface, barriers, railings, sidewalks, etc.

Diaphragm Loads are input as concentrated loads on each beam at a particular location along the span of the beam measured from the left bearing point. There are no restrictions on the number of diaphragm loads that can be added for a particular beam on a span.
