OBM Bridge Beam Template Import DGN

Cage Cluff — Fri, 23 Sep 2022 16:40:24 GMT

Is there a way to import the DGN file of a girder cross section into OpenBridge Modeler to create a new Beam Template for the OBM Beam Library? I see the option where you can save a template as a dgn, but no way to bring one back in. I'm looking to export then edit the beam shape using Microstation then re-import my new shape. This would save time compared to tediously typing in each point manipulation manually.

Define Itemtype by feature definition

Jaimin Patel — Mon, 26 Sep 2022 12:20:18 GMT

Hi Experts,

I have just updated to latest version of OBM (2022 R1), I have tried to explore Itemtypes and have few questions,

1. Is Itemtype library assigned to feature definition by default? (Eg. If I place a deck and have feature definitation as "deck" should I expect to see "deck - itemtype" in properties?

2. If itemtypes are not linked to feature difination, can I go to .dgnlib for feature difination and assign Itemtypes, so when I place a object in OBM and select feature difination, it will come with the itemtype library attached by default

3. When I manually attach an itemtype library in my working model by feature difination, I see doubling of itemtype properties, I assume software is assigning the itemtype by default and when I manually attach it, there are 2 itemtypes lib attached.

Can someone please give bit more clarity on how does the itemtype should work inside OBM?

Regards,

Jaimin Patel

How to Change the Default Folders of a Exsiting WorkSet?

Hi, Dear All,

How can we change the default folders of a existing workset in OpenBridge Modeler?

Thanks,

LEAP Bridge Concrete self-weight deflection

Sarah Larson — Tue, 30 Aug 2022 16:41:20 GMT

I'm using LEAP Bridge Concrete to design a prestressed box beam. In this design we are concerned about haunch heights. I was checking the beam self-weight deflection shown in LEAP vs. the AISC equation and another in-house structural analysis software. The AISC and in-house software deflection values match. LEAP deflection is more by about 7%. I have verified reactions and moment, so input weight is the same. I am using the same bearing to bearing span length and same E. How is LEAP calculating the Beam Self Weight at Release?

Thanks

Two bridges connection

Kenny Paz — Fri, 12 Aug 2022 20:54:00 GMT

Hello, I,m trying to create a Bent where 2 separate bridges meet, is this even possible to model in Openbridge Modeler? Ultimately, I want to transfer the model to LEAP to run the analysis.
