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…
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…
RC Pier - EV & EH loads
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…
How to obtain the out-of-plane governing load case in the report of pile lateral resistance
A few RC-PIER users recently asked questions about the two analysis options in the abutment design and the related footing design reports. Here is some clarification. In abutment design, when "Cap as continuous beam" is selected for the frame analysis…
Cannot specify Lane Loads in RC-Pier
When manually inputting live loads into RC-Pier, how do you specify a lane load. According to the help.... "For manually input live loads in AASHTO LRFD, this screen behaves slightly different. When a live load case is added in LRFD mode and edited, the…
RC-Pier: Best way to input vertical wind loads on pier.
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…
