Description

2nd order effects

The user can select from P-Delta, Moment Magnification, or None.  See the Engineering Theory for a discussion of these analysis procedures.

Analysis beta d

When P-Delta has been selected, the user can then select the type of Beta d value used, non-sway or sway (see ACI 318 for a discussion of these two factors).  The user can also select to input their own Beta d factor used in the analysis.

Cracking Behavior

Users are presented with three options for considering cracking effects: "No cracking," "Assume cracked," or "Crack at rupture."

No Cracking: This option assumes no cracking occurs during the analysis.

Assume Cracked: Selecting this option assumes that cracking has occurred.

Crack at Rupture: Opting for this mode triggers a stress check to determine if the design exceeds 7.5 sqrt (f’c).
