Hello,
At one of our projects, there was a breakdown of concrete batching plant for about 02 hours while casting post tensioned girder (girders poured to about half of height). The contractor ignored the advice of site engineer and poured the remaining concrete without roughening the surface...
Reducing the diameter of shorter column and reducing thickness of pilecap works, but I was wondering how did they achieve it with apparently same diameter and pile cap.
And Yes, I did consider column directly on drilled shaft but it comes out to be of very large diameter.
Can you please expand...
Hi everyone
I am designing bridges in a project with steep slopes. Overall topography of project is very similar to kicking horse canyon phase 4, British Columbia Canada (picture attached) Due to steep slope and to avoid cutting, both bents cannot be kept at same height.
The issue that I am...
Currently I'm working on design of bridge with integral pier. Usually, for typical non-integral highway bridges with pile/column bent pier, it is practice at our office to assume K value of 1.2 in bridge's transverse direction and 2.1 in longitudinal direction (AASHTO Table C4.6.2.5-1) when...
How are torsional moments in curved box girder bridge calculated. Can someone provide literature ? I'm doing analysis on software but I want to calculate them manually. I've used equations from pci and aisc manual but answers do not match with software.
Also, for a bridge with sharp...

It returns following error
No method 'GetAllTables' with matching signature found for class 'CSiBridge1.cDatabaseTables'.
However when I check methods by using methods(cDatabaseTables) it contains get all tables.I'll attach picture below.
and the error is in picture below
this time...

I'm using MATLAB. I don't know what might be wrong. table_data might be python specific and not working in MATLAB. I've attached image of syntax from CSi's guide.
My output parameters are right. Still it returns error

Hello
I need help regarding CSi API. I want use database tables with, I'm doing my inputs and output correctly, yet i'm getting this error. "No method 'GetAvailableTables' with matching signature found for class 'CSiBridge1.cDatabaseTables'." even though i checked using methods...
So far i've worked on the same configuration that you mentioned. Kept length of interior spans to 35 meters. however I've designed section without prestressing. I'm afraid pull-out forces due to sharp curvature might result in considerable thickening of webs which i haven't calculated as of now...
@BridgeSmith
Thank you. Currently I am working of model of 35x4m continuous box structure connected rigidly to substructure. After that I'll work on 2 span option as well.
Yes, we are working continuous structure now. Thank you.
Can you expand a little bit on this option? you are suggesting pier in middle with length of each span to be 50m approximately?
Vertical scale is set at 5xhorizontal. But I've edited the heights and mentioned actual heights i.e. 28meters without scale factor.
The terrain is mountainous. To reduce curvature, I'd have to get alignment relocated to downstream but it increases height substantially. Previously, the bridge...
I am planning a bridge over a waterbody. The high flood level is 15meter. I've attached images with two possible configuration, one with pier in middle with height of 28.4 meter while other configuration avoids the deepest part by 3.4m in height. There is an existing older bridge at downstream...
Is there any specific syntax to get girder forces of a bridge. CSi's documentation covers beam and area element, however the composite action of the two not covered anywhere.
Any sort of help and guidance will be highly appreciated.
