I would never use just one bolt for a gravity load-carrying connection, but for a beam seat on masonry, for example, where the bolt only provides a "lateral tie", such as the Simpson GLB beam seat, one bolt would be feasible.
Cajun- CNN stated 80% of the population voted Democratic (I failed to mention that). If Bush carried the state, probably because the voting machines were rigged anyway (sarcasm)
"Lack of competent leadership is the real cause of the lack of response for the people in the gulf coast."...
I have to keep repeating this over and over (it's pathetic, I need a life)...When you are doing your cases , you are getting an incorrect tension in bottom chord, due to the conversion of UDL to nodal loads. Merely a schoolboy exercise.
On CNN News, it was mentioned that the failure of the Feds to move quickly was due to the fact that 80% of the population voted Democratic.
Next time a Democratic-leaning state gets hit by a disaster, tornado, hurricane or otherwise, maybe they should change the name of their state to Iraq!
Sleeve is located at point of inflection. It is necessary to have the sliding capability since the floor deflect at differnet magnitude, and aluminum has large coefficient of thermal expansion.
JAE,
We almost always use full depth blocking, with 3 - 2 inch diameter holes for ventilation.
For steel joists, always either an "inverted" 2.5"x2.5" angle or 2.5" HSS as "blocking".
I agree with PBA - your explanation is very clear. I drew this thing out - including the 4:12 slope triangle. It is really obvious that in order to solve this problem, first turn off the computer, get a pencil, calculator, and common sense.
Reaction = 54x17/2=459 lbs
Tension in ceiling joist =...
To streamline your input, have an input cell that defines what knowns are being input, similar to the triangle solver that IRstuff provided a link for.
That input cell could be set up with data validation for 1,2,3,4 for the 4 different combiination types of input known data.
The function CHOOSE...
I agree with SacreBleu...if he is speaking of an open canopy, away from any building.
dik... your comment is valid, especially the phenomenom of pressure equilibrium.
