When using the "Generate Default Load Combination" feature, the load combinations generated are using different factors, like : - 1.4 for WS for STR GP 3, - 0.4 for STR GP 5, - and 0.3 for SER GP 1. LRFD 8 specifies 1.0 factor for all WS regardless…

How does RC Pier (LEAP SubStructure) account for skew when calculating the bearing reactions for the Auto Generated Live Loads. I can replicate the reactions when there is no skew, but I have issues when skew is applied. Any assistance on the matter would…

I am using the LEAP Bridge Substructure module to design a pier for a continuous 4 span structure using HS20 LFD loads. In the AASHTO Standard Specifications, it gives you a few options for the loading. One is that you can use a lane load with one concentrated…

I am using the Substructure module of LEAP Bridge Concrete. According to AASHTO LRFD, you can't have a truck on both the approach slab and on the deck, but you can have a lane load on both. When generating live loads for an abutment, there are two…

Does anyone have calculation verification for the live load auto-generation function in RC-PIER? Or has anyone else had problems verifying the LL output from RC-PIER?

Recently I am working on a transition bent which is a multi-column bent. The approaching span is simple span, and the main span is continuous-three-span. I am considering using the 3rd option for live load auto generation since the first two options …
