Upgrade Instructions

LEAP Bridge Enterprise V8i (SELECTseries 7) v14.00.00.19 incorporates the following enhancements and fixes to itself and its component programs:

LEAP Bridge v14.00.00.19

Enhancements:

A new option to specify minimum beam seat depth for all bearings on a support is now available
For skewed abutments and piers, user can now select an option which will draw edges parallel to deck in the 3D model and 2D views.
A new report showing top of cap elevations (for supports on either side of span) has been added.
A new option to export 3D model as solids instead of meshes on the export to DGN option has been implemented.
In order to improve the workflow when starting with ABC Wizard, the File>Save option in the component programs is now disabled. By simply closing the component program, data is saved back to LEAP Bridge model. In the preferences user can chose an option to have the program display a message with options to send/not send back to the main bridge model.

Fixes:

Input restrictions on minimum width and height of back-wall on abutments have been removed.
Barrier concrete quantities in the report were incorrect for some cases. Fixed now.
By default, the export of 3D model to DGN now uses Survey Foot and Survey Inches.
On export to DGN, H-piles now show correct EC data properties.
Some data flow corrections to support multiple bridges in a single file have been implemented.
A program crash due to missing pile patterns in library was fixed.

LEAP CONSPAN v14.00.00.19

Enhancements:

2013 Interim Revisions to the LRFD Bridge Design Specifications are now implemented. The primary change is phi factors based on strain limits rather than c/dt ratios and support for high strength steel.
A new option has been added to neglect the haunch contribution to section properties computation is now available. Program will only consider the self-weight only in this case.
Connection to AASHTOWare Bridge Design/Rating (formerly Opis/Virtis) is now updated to support v6.5.

Fixes:

Fixed program crash when working with layout of non-voided rectangular slabs
For flared girder geometry cases, if beams were detected to be laid out non-continuously, program prevented analysis from being run. Now only the warning is shown, but user can still run analysis.
Some users reported program crashes when generating Enhanced Report for Positive Envelope Stresses. Fixed now.
Positive Envelope Stress graph corrected to show the correct Limiting Stress for Service I limit state.
For Canada code, the dead load factors were printed as zero’s in the rating reports. Did not affect final results. Now fixed. Also some minor differences between summary report and detailed rating report were corrected.

LEAP CONBOX v14.00.00.19

Enhancements:

Limit State Design for India
LRFD Interims 2013
An option to include or exclude the secondary moment in cracking moment calculations
Improved analysis reports of truck/lane, live load, service/strength limit states, and substructure reactions with more clarity
Improved detailed bending design report for strain compatibility option
Added warning message when the anchor set length overlaps

Fixes:

Self weight of columns incorrectly added to bottom-of-column reactions in various dead loads (including barrier, sidewalk, railing)
The option “Use Single Lane DF” did not work for Tee bridge
Incorrect moment diagram of Strength I
Discrepancy in reactions to the self weight between different versions
Discrepancy in column height between the printout report and the definition in the model
Incorrect calculation of the cracking moment for California option
Incorrect calculation of the factored moment capacity per Canadian code
Incorrect report of PT internal forces at the Initial stage
Self weight of columns incorrectly subtracted from substructure reactions for load combinations
Column length in the design report did not match the input in the model
Double trucks and tandems were not considered in substructure reactions
Incorrect calculation of negative moment capacity in Tee bridge

Note:

In CONBOX v12.01.00.57 the modeling assumption for tendons crossing variable depth cross-sections was modified. The change was made to produce zero Vp for straight horizontal tendons. This change typically resulted in slightly higher required PJack force. However, it is realized that a straight horizontal tendon crossing variable depth cross-sections would indeed produce Vp, since the tendon axis would not be parallel to the sloping CG axis. V14.00.00.xx rolled back the change introduced in V12.01.00.57

LEAP RC-PIER v14.00.00.19

Enhancements for US, Canada, and India:

Limit State Design for India
LRFD Interims 2013
Rigid Links in pier caps over columns
Overturning check on longitudinal moment for substructure
Option to auto-design pier cap using a uniform steel configuration
Improved RCP algorithm to optimize memory using for huge number of load combinations and handle zero length members
Auto-generation of load combinations with wind loads for Canadian code

Following issues were fixed for US, Canada, and India:

Non-Tapered Segment was not allowed to be less than two-third the total Cap length
The stem wall in 2D plan view did not match that in 3D view
Unable to export displacement and rotation results of all combinations to Excel
Incorrect volume calculations of cap and column for the Variable Cap Shape option
Incorrect wind loads for pier column with non-uniform section along the height
Start Elevation in the detailed design report did not match that of the model in the Stepped Cap pier
Incorrect wind loads on columns under multiple wind attacking angles
Incorrect self weight of the abutment when the option of Integral Abutment Bridge was toggled on
Incorrect effective steel area of the top reinforcement of footing
Incorrect load effects in combined footing when columns were eccentric to pile cap
Incorrect shear capacity in two-way shear check on footing
System was unstable while print the controlling combinations in the analysis results
Irrelevant symbols showed up in the pile reaction report
Incorrect update of structure model when Extreme Event Seismic Group was added
Loads at bearings were incorrectly applied above the ledge in Inverted Tee pier
Input values of bearings were incorrectly retained in the strut and tie model
Rounding of input values of steel reinforcement did not allow the design procedure to proceed in pier column design
Incorrect height of wall pier was used in auto-generation of loads
Incorrect load effect of transverse moment Mzz in isolated footings

Additional issues fixed for US:

SERVICE III group was missing when the option “WS as per FDOT SDG 2.4” is checked
Incorrect distributed out-of-plane forces in columns for California design option
Flexural design report showed incorrect tension/compression control for California option
Incorrect implementation of Response Modification Factors for seismic load auto generation
Incorrect axial loads and moments imported from CONBOX to RC-PIER
Design footing for magnified moments did not work
Effective area of reinforcing steel was incorrectly calculated at ends of cap when 180 hook bars were specified
Incorrect minimum required steel in the column design
Incorrect note showed up when there was no red flag in the report
Incorrect height was used to generate lateral soil pressure in abutment for the option "Piles integral with cap"
Load effects of transverse forces were incorrect calculated for the pressure loads WS and WA

Additional issues fixed for Canada:

Incorrect cracking/fatigue check for footing cap
Incorrect calculation of required steel reinforcement at bottom of pier cap of the hammer head pier
Incorrect calculation of shear capacity provided by concrete
Incorrect auto generation of wind load combinations per Canadian code
Incorrect load factors of braking load in the SLS
Incorrectly calculated load effect due to the lateral earth pressure
Incorrect height of columns was used to generate wind load on pier columns
Incorrect two-way shear capacity for footing cap
Ce factor for live load auto-generation per Canadian code did not work
