Strut and tie model for steep strut angles
Strut and tie model for steep strut angles
(OP)
Hi all,
According to most of the STM references, the maximum struct angle is about 60-65 degrees. I encountered a case which an elongated column has to be supported by a 2-pile pile cap. But the struct angle is about 70 degrees when the column load is replaced by two point loads at column edge. To maintain the strut angle to 60 degrees, need to have a shallow pile cap, then the Tie force is very large and cannot accommodate r/f.
Is there anyone can assist please ?

RE: Strut and tie model for steep strut angles
Hi,
Angle restrictions apply when struts and ties are present.
Current modeling and other modeling will not cause ties in that geometry.
Therefore, I do not think that you need to observe angle regulations.
Modeling uses AStrutTie.
