How do I copy a pier to multiple locations in LEAP Concrete?
I have a multi-span structure with 3 very similar piers with variable pier caps. In the ABC bridge wizard I defined a generic rectangular cap pier since it did not have the variable depth option in the wizard. I have now redefined one of the piers with…
How to change the stress limits for the intermediate bent cap from normal exposure (=0.19 sqrt(fc) <0.6ksi ) to severe exposure (=0.0948 sqrt (fc)<0.3ksi) in leap bridge concrete
I need to change the stress limits for the bent cap from normal exposure (=0.19 sqrt(fc) <0.6ksi ) to severe exposure (=0.0948 sqrt (fc)<0.3ksi)
RCPier P-Delta Analysis increases axial forces in the column.
When running analysis with and without P-delta I noticed there is a substantial increase in the axial column force when P-delta is applied. At the node 1 the difference is about 300 kips. What could be a reason for such an increase? Any insight is appreciated…
Shrinkage Strain Load & Moment capacity error - LBC Substructure
I have bent that is being constructed in two phases so some shrinkage will happen on the first phase before the next phase is constructed. In the final condition, I could assume the entire shrinkage strain is applied to both sections but that will be…
LEAP Bridge - RCPier Centrifugal Forces Considerations
Hi,
There are cases where centrifugal forces produce a moment that actually counteracts the critical moment in the column, does RCPier consider effects due to vehicle cases without centrifugal forces as provisioned in AASHTO Spec (See below excerpt…
LEAP RC-PIER P-delta effect in load combinations
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…
