Hi all. In the design of a cable-stayed bridge, what is the allowable displacement of the A and H shaped towers under live load? Best regards.

Hi all. I hava some question about steel composite brige as follows: 1. To calculator stress point of section, Rm Bridge automatic use short-term section for live load and load case type Non-permanent and use long-term section for load case type Permanent…

Hi all. In continuous beam structures, the allowable downward deflection of the bridge under HL93 load is L/800. So may I ask what is the upward deflection of the continuous bridge structure under HL93 load? best regards.

Hi all. I have a question about Reinf crack for prestressed concrete as follows: If you calculator stress bot of section beam in MinMz_Service exceeding allowable stress tension limit is 0,5 x sqrt(f'c), you can calculator reinf area to control crack…

How do I calculate AX, IX, IY, IZ, AY, AZ, YD, and ZD for a T-BEAM bridge section in the general option in STAAD ?

Hi everyone, I finished model and analyzer in extradosed bridge ( pictures below are my cross section and internal force ) I want to see the reults of deck (I nternal force of deck , Influence lines of deck , Ultimate load check of deck,...), Can…

Hello everyone, I needs help about create PLSYS for ultimate check and fibre stress check in stages. Like the picture below, Thanks.

I am using Leap Bridge Concrete CONNECT Edition v17.01.01.07. I used ABC wizard to model a two span non continuous bridge (110'-104') with a 17.5 degree skew. The deck in span 1 is 66.6 ft while in span 2, it flares from 66.6ft in the interior bent to…

Is there a way to add a supplemental composite DW load for a poly wearing surface in Leap Concrete Bridge? I want to keep it separate from the Future Wearing Surface (Composite DW) load I already have. This is necessary to accurately calculate camber…

I am designing a 2-span precast prestressed beam bridge in LEAP Bridge Concrete CONNECT Edition v17.00.01.01. The bearing dimensions along the pier cap are shown correctly in the following view under the 'Substructure' tab: However, when you click…

When calculating the top and bottom stresses at the transfer and bearings, does LEAP take into account the development length? It seems that the stresses its calculating at the bearings and the transfer are higher than what they should be. Does LEAP use…

Hello, There appears to be a font compatibility issue. In the program LEAP GEOMATH V8i, it looks like you should be able to adjust the window in order to see the rest of the menu, however there is no option to move it. This issue is not resolved…

LEAP Bridge v8.1.0 incorporates the following enhancements: • The ABC Wizard can now directly read in alignment, cross-section and profile information from LandXML files. The bridge model can now be generated very accurately directly utilizing…

With the release of LEAP Bridge Enterprise SS5 v12.01.00.57, we are eager to get all of our LEAP product users onto the latest and greatest, however our environment is currently a mixture of LEAP Bridge Precast 9 and 10. Is there any supported upgrade…
