Auto Generated Live Load Cases in LEAP Bridge Concrete - Substructure
I am designing a hammerhead pier using the substructure module in LEAP Bridge Concrete. The geometry is a little odd...it's a hammerhead cap on a circular column. To compare the results for the cap design from the conventional sectional design & strut…
Leap Bridge Concrete Wall Pier - Moments at bottom of wall
I am using Leap Bridge Concrete to design a skewed wall pier. After analyzing the pier, I noticed that for the braking force, that the sum of the forces in the z-direction at the top of the wall did not equal the sum of the forces in the z-direction at…
Bearing Spacing Dimensions Differ Between Main Bridge Model and Substructure Module
I am designing a 2-span precast prestressed beam bridge in LEAP Bridge Concrete CONNECT Edition v17.00.01.01.
The bearing dimensions along the pier cap are shown correctly in the following view under the 'Substructure' tab:
However, when you click…
LEAP Bridge Substructure/RC-Pier LFD Live Loads in the Negative Moment Region
I am using the LEAP Bridge Substructure module to design a pier for a continuous 4 span structure using HS20 LFD loads.
In the AASHTO Standard Specifications, it gives you a few options for the loading. One is that you can use a lane load with one concentrated…
LEAP Bridge Concrete v16.01.00.10 - Substructure - Can Pier have a tapered cap and have a off-set column?
I try to create a pier with a tapered cap, which is unsymmetrical and with a column near one edge.
Is it possible? I know i can create a symmetrical cap with a column offset from the center, but the location of non-tapered segment cannot be modified…
RC-PIER Live Load Auto-generation verification
Does anyone have calculation verification for the live load auto-generation function in RC-PIER? Or has anyone else had problems verifying the LL output from RC-PIER?
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…
Walls in RC Pier
I am designing a two stage pier wall. There is no option for just a wall in RC pier. Is there a way to trick the program, I have tried a couple of different options but none have worked. The top wall is tapered in both directions and the bottom wall does…
Re: RC-Pier Load Input
This feature has already been added in RC-PIER and will be in v09.00.00.xx scheduled for release in May 2009. Users will be able to specify a text file from which the values can be read in from. This feature will be available for both LFD and LRFD, and…
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…
