Structural Analysis

|---|---|---|---|
2nd order effectsSlenderness 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). | ||
Cracking Method | The user can select from the ACI Table 6.6.3.1.1(b) method or the Robert F. Mast’s procedure from the PCI Journal. | ||
Effective Length Factor, k | Effective length factor k will be used when computing the slenderness limit and the buckling load. | ||
Slenderness limit, kl/r | Slenderness limit will be used to check if slenderness effects can be ignored. This input will only be visible when Slenderness Effects is set to ‘None’. | ||
βds method | Determines if beta d sway should be computed by the analysis or user defined. | ||
βdns method | Determines if beta d non-sway should be computed by the analysis or user defined. |
Development Options
Header | Description |
|---|---|
Ktr | Value to fine tune development length calculations. |
Bar Confinement Provided | The bar confinement input is used for computing both the development length of hooked bars in tension and headed bars in tension. This determines if development lengths should be increased through the use of the confining reinforcement factor and the parallel tie reinforcement factor respectively. |
