RE: Non Linear Analysis
Nonlinearity can be geometric and/or material. Geometric nonlinearity stems from large deformation so much so that the structural stiffness changes and needs to be recomputed for the deformed shape. Material nonlinearity on the other hand is characterized…
RAM Concept nonlinear springs
Does RAM Concept have the capability to model nonlinear point springs or nonlinear supports for columns? I have a colleague who's trying to figure out some pile reactions but is unsure if RAM Concept is the right tool to use. The piles have a multi-linear…
Non-Linear Cable Analysis of a steel canopy in STAAD
Hello everyone,
I have this problem. The structure is a steel cantilever canopy supported by cables. What I understand is that, I need to model the cables as tension only members, and to use the advanced non-linear solver (done). what I want to do is…
NON Linear Analysis
Hi everyone! I am currently doing a project wherein I am required to perform a non linear analysis on a TRUSS tower. With regards to this (and sorry for the NOOB question), how do I perform a Non Linear Analysis in STAAD and why does the help file say…
ACI 318-08 Provisions for Slenderness
I am curious as to how practicing engineers will interpret and utilize the provisions for slenderness that are coming in the latest version of ACI 318.
I am referring specifically to Section 10.10. The '05 edition of the code gave the engineer…
