Element Type
RC column / RC brace / RC wall element
P-M Calculation Method
Select the type of P-M Calculation Method.
Keep P constant : Display the ratio (Rat.= Member Force / Ultimate Strength), wherein the ultimate strength is determined based on the same axial force as that of the specified load combination(P).
Keep M/P constant : Display the ratio (Rat.= Member Force / Ultimate Strength) wherein the ultimate strength is determined based on the same eccentricity ratio as that of the specified load combination (P,My and Mz).
