Modular Ratio Comp. Method [EsbyEc/User Input]: The modular ratio can be computed either by dividing the modular ratio of steel by that of concrete or by using a user-defined input. This parameter allows users to specify the method for calculating the modular ratio.

Modular Ratio: If the Modular Ratio Comp. Method is defined with the option 'User Input,' a modular ratio can be defined manually. Otherwise, this parameter will be marked as not applicable (N/A).

Input Data Preference [Override Deck Rebar/Use Deck Rebar]: For deck rebar to be used in girder code checks, users are provided with two options. The code checks can either be conducted using the modeled deck rebar or with new rebar definitions.

If the input data preference is defined with the option 'Override Deck Rebar,' the parameters listed below can be used to define the rebars for code checks. Otherwise, if the input data preference is defined with the option 'Use Deck Rebar,' the parameters below will not be applicable.

Lumped Top Reinforcement Area within the Effective Width: This parameter can be used to specify the lumped reinforcement area within the effective width when overriding deck rebar.

Distance from the CL Centerline of Top Bars to the Top of the Deck: This parameter can be used to define the distance from the centerline of the top reinforcement bars to the top of the deck.

Lumped Bottom Reinforcement Area within the Effective Width: This parameter can be used to specify the lumped reinforcement area within the effective width for the bottom deck rebar.

Distance from the CL Centerline of Bottom Bars to the Bottom of the Deck: This parameter can be used to define the distance from the centerline of the bottom reinforcement bars to the bottom of the deck.

Deck Rebar Material: This parameter can be used to specify the material used for the deck rebars.

Concrete Creep Adjustment Factor: This parameter can be used to define the adjustment factor for concrete creep in calculations.

Cover Plates

Cover plates are additional plates that are attached to the flanges of girders to enhance the flexural capacity of the girder over a certain section of the beam. The load rating object provides users with the option to add side and cover plates to the top or bottom flange. Section modulus and stress values will be calculated based on these inputs under live loads. However, actual girder plate dimensions will be used for other permanent loads.
