RFreund is right in that was the question I was asking. I understand the load case for overturning/sliding, in that projecting the earth pressure force against the virtual back behind the heel neglects contribution of its vertical component to resisting overturning/sliding. The more I think...
Sorry its my first time with uploading, but here is the pdf.http://files.engineering.com/getfile.aspx?folder=ae8bb149-f531-4b5d-8d72-4bf724296291&file=FBD_&_Reference.pdf
To be a little more specific with my question, the surcharge on the wall is from a Cooper E 80 live load. I have attached a sketch of the offsets and a reference I found from Union Pacific RR.
I have read Bowles' discussion regarding the Boussinesq equation, and am using the version provided...
I have searched the web for an example and am unsuccessful in finding a retaining wall design using boussinesq's equation for surcharge. Does the surcharge have to be calculated twice - once applied to the stem and once applied to the virtual back behind the heel - to design the stem...
Hi All,
Per Arema code, I am using the trial wedge method to design a retaining wall with surcharge. Every example I can across has the wedges begin at the end of the heel. Does anyone know what to do with a surcharge load that is located on the heel?
I assume the weight of the surcharge load...
All,
I am trying to design a steel-reinforced elastomeric bearing for a simply-supported prestressed box beam bridge. Per AASHTO Section 14.7.5.3.2, the max horizontal displacement of the bearing may be 65% the design thermal movement range combined with the movements caused by creep...
