A new feature of using rigid links in the structure model in RC-PIER has been added in LEAP Bridge Enterprise v14 per the request from Michigan DOT. Below are some basic facts about the new feature.
A rigid link, simply put, is one which does not…
Out-of-plane reactions distributed to pier columns for AASHTO LRFD with California option in Substructure
A feature has been added in RC-PIER per the request from Caltrans. This feature is about how the out-of-plane reactions to external loads from superstructure are distributed to pier columns in an integral pier.
For those loads which have both vertical…
Frame Analysis Method for pile cap abutment and pile bent in RC-PIER
In general Frame Analysis method, cap is modeled as a beam and piles/stem walls are modeled as columns.
In the “Cap as continuous beam” option, the cap is analyzed as a continuous beam. To mimic the continuous beam” analysis for the cap, the axial stiffness…
RCPier - Response Modification
I am using Leap Concrete Version 18.02.02.03 for a multi column pier design that includes seismic forces. I need to apply a response modification factor for the columns and the help guide states that this can be modified in the Seismic Parameters. However…
