Hello, Is LEAP Bridge concrete / RC-Pier capable of having a structure simple span for dead load and continuous for live load (SDCL)? Thanks.

How does LEAP Conspan apply multiple presence factors if live load distribution factors are entered manually? If distribution factors are entered manually, is it up to the user to apply the multiple presence factor to the manually inputted distribution…

Hi, guys I recently ran into the issues as the text is too small in Leap Bridge Concrete Bridge as shown below. Does anyone have an idea to solve this problem? Thank,s

Hello, I am having an issue where my battered pile look correct in my OBM model, but when they are transferred to LEAP they are backwards. I used the same template for the begin and end abutments, and just changed the orientation in the properties.…

Hello all, I have a few questions and concerns regarding OpenBridge Designer (version 10.10.00.26) that I hope someone is able to answer. Please find my questions below: 1. I have a situation where multiple bridges share the same substructure (abutment…

I am currently design 4 bridges in LEAP Steel v19 but am encountering an issue with the tool to automatically generate loads for the wearing surface of the structure. The bridges are all of a similar type, but some are wider than others and one is on…

I have several questions and need clarification on several aspects of the load generation in LEAP Bridge for substructure design. 1. For WS, is the "barrier height" in the Geometry tab used for any other purpose besides determining WS? I want to use…

Following this suggested format to import cap loads. No success. Need help.

When checking Show P-delta Effects in the Analysis tab, are the values shown represent values with p-delta effect? For example, are the column/shaft moments magnified with p-delta factor in these load combinations (with a "C" on the end of the LC#)? If…

Hi, I've encountered a scenario in prestressing design where with the decreasing of total number of strands, the Mu provided somehow increases. Attached are two screenshots with different total number of strands & corresponding Mu. -Total number of…
