EFFECT OF P-DELTA
EFFECT OF P-DELTA
(OP)
HI
i made high rise buidling in etab programm with high 100 meter but i found this massage in the analysis file
CURRENT P-DELTA ANALYSIS ITERATION = 1
MAXIMUM NUMBER OF ITERATIONS ALLOWED = 2
CURRENT DISPLACEMENT MAGNITUDE = 0.044349
RELATIVE DISPLACEMENT CHANGE = 0.001288
RELATIVE DISPLACEMENT TOLERANCE = 0.001000
ITERATION DID NOT CONVERGE
so i want to ask if that nesscssary to change the relative displacement tolerance or want can i do?
thanks for all comments

( ITERATION DID NOT CONVERGE) because the relative displacement more than the tolerance displacement
so i increase the tolerance but i do not know if that right way or i should to calcuale the tolerance before i start calcualtion.
RE: EFFECT OF P-DELTA
have you checked if your relative displacement value is within the code prescribed maximum?

Do an Integrity Check if the program does it. And Do a linear static analysis first to see if the deflection is exceeding under say wind. Then check the specification you did for the P-Dalta analysis type (I don't kow ETAB well).
