Beam Checking

AIK-SRC2K, AIJ-SRC01

Verify the strengths of SRC members using the results obtained from the analysis of the entire structure and additional strength verification data according to the SRC Composite Columns Design Code of American SSRC (Structural Stability Research Council).

It supports the following functions:

- Live load reduction factors
- Correction factors for seismic forces
- Strength verification of all the members for moving load

From the Main Menu select Design > SRC Code Check > Beam Checking

Shortcut key : [Ctrl+7]

The strength verification results sorted by members are based on the maximum negative and positive moments and shear forces calculated at the positions (I, M & J) of each member in accordance with the load combinations for concrete design. The strength verification results sorted by properties are based on the maximum results obtained by considering all the members and sectional locations pertaining to each section property in accordance with the load combinations. The results appear in blue when the strength verifications for the given section properties and rebars are satisfactory, otherwise they appear in red.

Strength verification results can be performed by using the information on steel members, main rebars (diameter, number), sub-rebars (diameter, number) and design parameters entered by the user.

AIK-SRC2K Code Checking Result dialog box

MEMB: Member number

PROP: Section property number

Span: Length of beam member

SEL: Member selection for re-verification of strengths and production of results

Note
The members can be selected or cancelled with the Space Key.

Section: Section name or steel section name

Bc, Hc: Width, height (depth) of SRC beam member

Material: Steel material name entered by the user or stored internally by the program

sFy: Yield strength of steel

f'c: Design compressive strength of concrete

Fyr: Design yield strength for main rebars

POS: Strength verification points (I, M, J)

The checking results at M reflect the maximum negative and positive moments and shear forces at 1/4, 1/2 and 3/4 points.

CHK: Status of strength verification results

= "OK": Design strength exceeds the factored negative and positive moments and shear forces.

= "N**": Design flexural strength is less than the factored negative moments.

= "*P*": Design flexural strength is less than the factored positive moments.

= "**V": Design shear strength is less than the factored shear forces.

= "NP*": Design flexural strength is less than the factored negative or positive moments.

= "*PV": Design strength is less than the factored positive moments or shear forces.

= "N*V": Design strength is less than the factored negative moments or shear forces.

= "NPV": Design strength is less than the factored positive and negative moments or shear forces.

AsTop: The area of main top rebars entered by the user

AsBot: The area of main bottom rebars entered by the user

N(-)Mu, LCB: Maximum factored negative moment occurring in the relevant member or section and the corresponding load

combination

N(-)Mrs.: Resisting flexural moment about the negative moment of the reinforced concrete and steel

Rat-N: Factored negative moment / Negative design moment strength, which shows in red if it exceeds 1.0

P(+)Mu, LCB: Maximum factored positive moment occurring in the relevant member or section and the corresponding load

combination

Rat-P: Factored positive moment / Positive design moment strength, which shows in red if it exceeds 1.0

Vu, LCB: Maximum factored shear force occurring in the relevant member or section and the corresponding load combination

Vrs: Allowable shear strength for the reinforced concrete and steel

RatV: Factored shear force / Design shear strength, which shows in red if it exceeds 1.0

2. AIJ-SRC01

AIJ-SRC01 Code Checking Result dialog box

Fc: Design compressive strength of concrete

mFy: Design yield strength for main rebars

wFy: Design yield strength for steel members

N(-)rsM: Resisting flexural moment about the negative moment of the reinforced concrete and steel

PN(+)rsM: Resisting flexural moment about the positive moment of the reinforced concrete and steel

Q, LCB: Maximum factored shear force occurring in the relevant member or section and the corresponding load combination

rsQ: Allowable shear strength for the reinforced concrete and steel

Rat-Q: Factored shear force / Design shear strength, which shows in red if it exceeds 1.0

Other items are identical with those of AIK-SRC2K.

• Common Control

: Display the applicable code for strength verification.

"Sorted by Member" displays the results of strength verification for the maximum factored negative moment, positive moment and shear force at the sectional locations (I, M & J) extracted from all the load combinations.

"Sorted by Property" displays the results of strength verification of the member producing the maximum factored negative moment, positive moment and shear force at the sectional locations representing all the members attributed to the relevant section property. Since the results do not pertain to a single member, MEMB (member number) is "0".

Once Property is selected, SEL controls all the members attributed to the same section properties.

: Display the unit system selected by the user.

: Select all members.

: Cancel the selection of all members.

Re-verify the strengths of the selected members. When the strength re-verification is executed from the results displayed by section properties, all the members attributed to the same sections are included.

: Display detail strength verification results.

: Display simplified strength verification results.

: Select the location data to be included in Detail output.

: Produce the strength verification results in summary calculations for the selected members.

: Produce the strength verification results in detail calculations for the selected members.

The design results "Sorted by Member" support the detail calculations.

Produce the summary list of strength verification results for the selected members.

The design results "Sorted by Property" include the maximum forces (results of maximum reinforcing steel) calculated at each sectional location (I, M & J).

When RatN, RatP and RatV exceed 1.0, "*" appears to the right of the output values.

= All: Produce all the strength-verified results in the Checking Results dialog box

= OK: From the strength-verified results, display only the results that have met the design requirements (OK) in the Checking Results dialog box

= NG: From the strength-verified results, display only the results that have not satisfied the design requirements (NG) in the Checking Results dialog box

: Check in the option to select and highlight the selected members in Model View.

: Close the dialog box.
