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)

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…

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…

I'm trying to apply vertical wind loads on a pier per AASHTO LRFD 3.8.2. The problem I have is with the load combination generation. This load shoud only be applied during Strength III and Service IV limit states. Is there a way to specify this for the…

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…
