LEAP Bridge Steel CONNECT Edition V17 Update 1 contains enhancements and bug fixes.
The following enhancements and bug fixes are available in this release.
Major Enhancements
- Centrifugal Force Application
The effects of centrifugal force and cross-section superelevation on wheel loads are introduced in live load calculations when the bridge is on a curved alignment.
- Travelway Definition
This feature is intended to locate the live load lanes within certain limits on the bridge deck. Therefore, conservative analysis/design results for exterior girders may be prevented by the user modeling bridges with parapets, medians, sidewalks, etc.
- 64-Bit LEAP Bridge Steel
64-Bit application provides faster analysis as well as superior capability of handling large/complex bridge models.
- Automatic Plate Generation for Tub-Girder Bridges
Similar to I-girders, now, LEAP Bridge Steel is offering initial plate size generation for tub-girder bridges depending on the bridge span length and configuration. Initial plate sizes, which satisfy AASHTO LRFD geometry checks, are a good starting point and makes the ongoing iteration process for the final plate sizes much easier.
Additional Enhancements
- Superimposed Dead Load Distribution to Girders
Automatically created superimposed dead loads (such as sidewalks, parapets, etc.) can be distributed with certain percentages to individual girders.
- Transfer of Centrifugal Force, Pedestrian Load and Temperature Load from Superstructure to Substructure.
- Wearing Surface Definition
Wearing surface limits, unit weight and thickness can be defined, and the corresponding wearing surface load is automatically calculated and applied to the girders.
- Load Rating Report Enhancements
More detailed and intuitive load rating reports are introduced.
Bug Fixes
This release fixes the following issues:
- Incorrect bearing spacing in skewed supports for substructure design
- Error in automatic “Self Weight Slab” load creation for multiple simple span models with single stage deck placement
- Graphical error in 3D viewer for tub-girder bearing locations
- Incorrect material unit weight for lightweight concrete
