I am using the Aluminum Association's Aluminum Design Manual to design an aluminum frame with extruded tube shapes and welded connections, and I am a little out of my element working with aluminum instead of steel.
What is the maximum allowable size of a fillet weld based on the thickness of...
I am referring to ASCE 7-02, Section 6.5.8.2, Gust Effect Factor for Flexible or Dynamically Sensitive Structures.
The equation for the gust effect factor (G) includes the variable R, or resonant response factor.
The equation for R includes the variable beta which is a damping ratio.
As far...
The moment magnification factor for nonsway frames equals
Cm/[1-Pu/(0.75Pc)]
which is equation 10-9 in ACI 318-02.
As the column gets longer, the critical load Pc gets smaller, and the factor approaches infinity as 0.75Pc approaches Pu.
My question is, what happens if Pu > 0.75Pc?
This...
