Below shown is connection for truss.
My primary objective is to check the adequacy of weld (in purple)
Member I is top chord of truss, II vertical and II diagonal truss member.
We have shear force on member I at the location of connection, say 300kN (this will...
Hi all..thanks all for your valuable replies..Yes I understand that when there is negative pressure (or to re-phrase P/A-M/Z is negative) there is re-distribution of soil pressure since the bearing area will be reduced.
My question was if the overturning FOS >2 and the maximum bearing pressure...
@Agent666 Thanks for your reply. And yeah by negative pressure i mean there is an uplift (P/A-M/Z is a negative value). I guess some codes allow certain percent of uplift but I can find a reference for that in ACI or ASCE. And yeah since P/A-M/Z is negative, the reaction of course does not fall...
Hi all.. i am designing a tower crane base. The footing is safe in overturning although it has about 25% of its area in negative pressure for out of service condition. The design is carried out based on ACI code. I am not able to find any clause related to maximum percentage of negative pressure...
