P-M Calcualtion Method

 

 

 

When designing selected RC column, brace, wall members,"Keep P constant" method  and "Keep M/P constant" method can be selectively applied

 

 

 

From the Main Menu select Design > Design > RC Design > Boundary Element method By Wall ID.

P-M Calculation Method

 

Select the type of P-M Calculation Method.

 

Keep P constant  : Display the ratio (Rat.= Member Force / Ultimate Strength) when the ultimate strength is determined based on the same axial force as the specified load combination(P).

 

Keep M/P constant : Display the ratio (Rat.= Member Force / Ultimate Strength) when the ultimate strength is determined based on the same eccentricity ratio as the specified load combination(P,My and Mz).
