LEAP Steel

Kyle Berg — Wed, 16 Sep 2015 12:58:40 GMT

I am trying to investigate LEAP Steel as a viable option for Steel Design and have run into a few problems. I am currently working on a 3 span curved plate girder.

1. If I have multiple units within a bridge (2 bearing lines at a pier), is there a way to have the girder section end before the CL of Pier? I have offset the bearing and stopped the slab where I need to, but the member definition states that the girder section has an incomplete section. I do not want to include this additional length of girder section for bearing reactions.

2. Under Pier/Abutment locations, what is the intent of the "Offset to Bridge CL" option? My baseline is not centered on the bridge, so I assumed that I should enter a value here to offset the center of piers and abutments. Graphically this did not occur and the piers are still centered on the baseline. Also, it appeared to alter my span lengths when it came to member definition.

3. When defining crossframes, the graphics do not match the intent from cross-frame/diaphragm definition. I have defined my diagonals based on the top of the member. At the top of the crossframe the offset appears to be correct in the graphics. In the bottom of the crossframe, the offset is shown much larger than the input value.

Thank you for your assistance.

Open Bridge Modeler - Create Cross Sections

Kyle Berg — Tue, 21 Feb 2017 21:11:55 GMT

I'm currently running version 08.11.10.42 of Open Bridge Modeler. When anyone tries to cut a cross section using the following tool, the program crashes repeatedly. Has anyone else had this issue with this version? When is the newest version of OBM being released so I can fix this problem? Thanks

LEAP Concrete - Superstructure Reactions

Kyle Berg — Fri, 02 Jun 2017 17:17:33 GMT

I am using Version 16.02.00.01 of LEAP Bridge Concrete to determine superstructure reactions for pier design. Below are my Service I Reactions

Design Truck

Live (Max) = 109.7 kips

Truck = 68.6 kips

Lane = 41.0 kips

Double Truck

Live (Max) = 128.6 kips

Double Truck = 87.6 kips

Lane = 41.0 kips

I'm confused, the program user manual states that the 0.9 factor for double truck is internally coded. If so, how can the Lane Load reaction for Design Truck and Double Truck be the same? Is the 0.9 factor not included as part of these reactions?

Thank you

Deck Elevations

Kyle Berg — Wed, 05 Apr 2017 19:34:09 GMT

I'm trying to create deck elevations at even increments along the bridge. My bridge is skewed so I'm wanting to place the points parallel to the start support. The problem I'm having is along the baseline, it shows the correct number of points (7), but along the gutterlines and beam lines, sometimes it only shows 6. Is there a reason why?

OBM - Slab Display Problem

Kyle Berg — Wed, 05 Apr 2017 18:26:24 GMT

For my skewed bridge on a curve, my slab is showing up past the abutment centerline (See Below. However, no offsets are provided to extend the deck beyond the centerline. Is there something else I'm missing?

Top of Deck Elevations/Tracking

Kyle Berg — Wed, 30 Nov 2016 21:53:46 GMT

Is there a way to track elevations along the top of the deck? This would be similar to using the "Analyze Point" command under Analysis & Reporting for along a DTM. There are times where deck elevations are needed at random locations (vertical clearance) and the ability to track elevations along the deck would be very useful.

Thanks,

Kyle Berg

OBM - Abutment Display Error

Kyle Berg — Fri, 18 Nov 2016 21:29:38 GMT

The depth of my Abutment Pile Cap displays correctly when shown in the "Edit Abutment" window but is not being shown correctly in my 3D model. It is currently shown being shown much deeper.

I also have a few general comments/suggestions regarding future enhancements:

- Provide ability to automatically adjust footing off of multiple controlling terrains. There are some areas that my footings are controlled by existing ground and some controlled by proposed ground.

- Ability to copy up 3D shape to dgn to add visualization features. Currently if I want to show this to a client I have to export it to a google sketch up format and then re-import it.

- Vertical clearance - clash detection is ok for knowing you have enough vertical clearance in some locations but this is a bridge/transportation specific tool. Being able to define a corridor and have it look for and call out minimum vertical clearance would make this a more intelligent model.

Thanks
