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…

How do I install LEAP RC Pier v14.0019 with our selectserver? It used to install fine. Now when we try to install on a PC,it asks for the correct activation and selectserver info which we enter then it says its activated, When we click on the executable…

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…

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…

I am using Leap Bridge Enterprise v14.00.00.09 in a Win7 environment. When I open the Geomath and Conspan modules, they work fine. When I open RCPier, it gets to a screen which says "Loading Project File" and then crashes, and it sometimes gives me a…

The attached file shows the output from the cap design module of RCPier v14. Can you tell me why there is a point where phi*Vn=504 and Vu=72.5 yet phi*Vn < Vu? Is this result spurious or is there a reason for this? Also, how can I tell what the most…

How does RC Pier calculate the lateral pile resistance for battered piles? Thanks.

I am designing an abutment using RC Pier. Under the Loads tab, I input/generate EV & EH loads. However, when I run an analysis and review the load combinations the vertical or horizontal earth loads are all "0". It appears that these loads are being applied…

We are working a substructure design in which, due to the geometry of the roadway, it may be necessary to have the column rotated at an angle from the orientation of the pile footing on which it sits. In the past we've had to handle this via calculation…

I noticed my live loads were larger when I auto-generated them in RC-Pier than compared to when I imported them from Conspan. Is there a reason for this? This yields a more conservative pier design, but is it accurate? Thanks.

I have created a model of the roadway in Conspan and then generated the loads and exported them into a text file. I have also created a model of one of the piers for that bridge. When I go to import the loads from the text file I receive an error message…

Hello all: I am having an extremely difficult time getting through my bridge design on LEAP bridge. Especially while working in GEOMATH and RC PIER. In GEOMATH: Problem #1: Back when I was trying to make minor adjustments to the geometry of the…
