Construction application: Need best suited adhesive for application of attaching thin finished painted aluminium window guards (window bars) to installed finished painted residential apartment metal window frames. Contact area available is two flat smooth strips (one on each side of window...
What i did earlier was earlier that i was taking the equilbriating force at the beam column junction , that is in the upper columns is (M5+M6)/L and (M7+M8)/L(directed towars right(negative)
and lowe columns the equilbriating force as (M9+M10)/L and M11+M12)/L( directed towards the...
Austim,
My profound gratitude to you!!Thanks a lot---Much grateful
Suppose i take the left hand side upper column as a free body with colckwise moments at the ends.(Lets us say for a while that both the upper and lower colun are fixed at the ends)
Let us say for the left hand side upper...
H9, H11 are the horizontal shears corresponding to lower columns .In Wang's problem he has directed H9 and H11 to the right.H6 , H8 are the horizontal shears corresponding to upper columns .In Wang's problem he has directed H6 and H8 to the left.
This means clockwise shears positive????
Then he...
OK,fine.But still there is a problem. If there is a horizontal force of 20KN.acting to the right at that joint Wang puts it in the eqilbrium equation as -20??????Should'nt it be +20??
Thanks again for the reply.Much obliged.I did not mean that both the upper and lower columns will impose forces to the right.What i was confused was the sign convention Wang was following.I assume that when we write the equation of equilbrium any force (irrespective whether in upper or lower...
Hello :
Thanks very much for the reply. What i am trying to follow is:
I assume horizontal force acting to the right as positive(because we have assumed sidesway to the right as positive).Then based on clockwise moments at column ends(as we have for moment equations) i get horizontal forces .Now...
Thanks very very much for the reply.May be the doubt is a fundamental one.In the analysis by slope deflection method, say we are analysing an unsymmetrical rectangular rigid frame(single bay), while writing the equilbrium equation for the sidesway to the right, considering the joints at the...
Anyone having a copy of C.K.Wang Intermediate Structural Analysis.I was brushing up my analysis fundas for an important project coming up but have a very important doubt to clear from this book.This is making me lose sleep!!!!!Please help.If anyone has the book plz respond for further discussion.
