• LEAP Substructure - Full height abutment on piles - footing reinforcement design

    Hi - I'm designing a full height abutment and wingwalls on a shared footing supported on piles. LEAP has calculated an extremely large design moment and I can't quite back into the number. Can you explain how the software determines the maximum design…
  • Footing design results issue

    I am trying to extract footing design results and I noticed that it is getting struck/broken and closing out. When I uncheck design footing using P-delta effect it is producing results. I placed the LEAP file in the following link in addition to the screenshot…
  • LEAP Bridge Concrete Substructure Auto-Design

    Hi, Dear All, Please see the following picture. Questions: 1. Is it possible for us to look into the footing design calculation details in LEAP bridge substructure? 2. The required bar area is constant through the footing for both X & Z directions…
  • Two-way Shear Calculation for Pile Footings

    How does RC-Pier compute the two-shear footing demand for a pile footing? I have the following pile reactions. Even if I assume all the piles are outside the critical region and sum up all the max pile reactions, I get 1562.7 kips. However, the two…
  • LEAP Bridge Concrete - Combined Footing Design

    I have two issues when designing a combined footing. - Issue 1 has been reported by someone here previously and was never resolved or updated. It is about reinforcing of the combined footing not "developing" or being found at the edges of the footing…
  • Footing Design

    Hello, I'm running LEAP v18, and, I have two questions regarding the Substructure module:: 1. In footing design, do the factored pile reactions include the self weight of the footing?? 2. If not, how does the footing design account for it. Thank…
  • RCPier - Spread Footings on Rock vs Soil

    Hi there, I'm checking a design calculation for an abutment on spread footings done in LEAP RCPier. I couldn't find any information in the user manual or input/analysis tabs to determine how bearing pressure is calculated for a wall bearing on soil…
  • RC Pier - Two Column Combined Footing Design

    The flexure check location in X direction is from one edge to the other edge. I don't know why there is As_req at the edge of the footing. I am new to footing design. Some one helps please~ THX
