I have attached the problem, AASHTO and EM solutions. I think the problem is caused by the AASHTO angle definitions. Cheers, Steve http://files.engineering.com/getfile.aspx?folder=9a1ce548-b421-4ec7-842c-d944db79fb7e&file=Question_5_SE_Exam.pdf

Hi Philip, AASHTO defines delta as the angle between foundation wall and a line connecting the point on the wall under consideration and a point on the bottom corner of the footing furthest from the wall. per AASHTO delta = tan^-1(14/4) = 1.29 rad, measured from the wall to the far line...

Hi RFreund, The AASHTO equation and diagram are in the attachment, not the complete section. All references I have use the EM equation with the exception of AASHTO. I will contact someone at AASHTO and hopefully receive an answer to how they arrived at their equation. I do not believe soil acts...

PS I forgot to include the AASHTO definition of δ: δ = angle between foundation wall and a line connecting the point on the wall under consideration and a point on the bottom corner of the footing furthest from the wall (rad.) (C3.9.5) (3.11.5.3) (3.11.6.2) Cheers, Steve

Hi RFreund, AASHTO Definition: α = angle between foundation wall and a line connecting the point on the wall under consideration and a point on the bottom corner of the footing nearest to the wall (rad.) The solution manual for the problem defines it as: The angle α is the angle between the...

Hello, I am studying for the April SE. I have a question on the calculation of the horizontal pressure due to a uniformly distributed load. Using AASHTO section 3.11.6.2 and EM 1110-2-2502 return very different values, please see attachment. If X1 is 4 ft, X2 is 14 ft and z is 4 ft with a p...

Hi Everyone, I am looking for a notched wide flange beam seat at a steel girder design example. The beam seat depth must match the steel joist seat and a slotted steel plate is welded to the web to from the seat. Does anyone have a reference or example of this? Thank you, Steve
