Implementation of fatigue design for cross frame individual members

In the ‘Code Checker Results’, the program summarizes for each girder all the critical load combinations, AASHTO code and controlling performance ratio. As in some diaphragm locations, the program is stating the girder is controlled by fatigue and...

Evaluate the use of Lambda excess reinforcement for development length of steel used in design

I agree that the excess reinforcement factors would be different for each POI and load case. That is one reason most engineers conservatively ignore that factor. A simple or temporary solution is to set that factor equal to 1. I believe that AASHT...

OBD-- Leap Bridge Steel Cross Frame to be assigned as primary or secondary elements as additional criteria

From the user: "I have a straight steel bridge no skew and it is classifying cross-frames as primary members. Is there away to set cross-frames as secondary member for kL/r check?" This happens because All elements are only set as primary, without...

Add capability for loads to be applied to the footing

In LEAP substructure modules, it would be helpful to be able to add loads to the footing, other than vertical earth. Sometimes there are miscellaneous components of the pier/abutment where the weight needs to be considered, but are not a part of t...

camber at .1xCLBRG span in LEAP Concrete

Add an option to get camber given at 10th points on the clbrg span instead of the precast span. beams are being set at a certain elevation at CLBRG so the camber up from CLBRG is what we need to design geometry around, not camber up from end of pr...

leap bridge steel -- Add Str III combination to default combinations

The user insists of adding Str III as a default combinations. It may be useful to create a default Str III combination (since now we have WL considered under design) instead of forcing the user to create a new combination that accepts WL. Please s...

LBS add a special distribution factor for deflection (AASHTO Art. 2.5.2.6.2)

Under commentary C2.5.2.6.2: "For straight girder system bridge, this is equivalent to saying that the distribution factor for deflection is equal to the number of lanes divided by the number of beams"

Allow for different shaft fixity in one model

A column on drilled shafts can have different fixity locations for different load cases. Suggest allowing analysis of the same bridge with different fixities rather then needing to create multiple models with varying fixities for simplicity.
