Concrete Design Results

Check the design results of RC members by numerical components and contours.

Reinforcing information such as rebar diameter, rebar spacing and required reinforcing steel area can be displayed.

Among the design results of RC members, the ratio of axial stress can be checked separately. (But this is applicable to the column and wall members only.)

Note1
In case when Update Rebar is executed after the member design, 'Re-calculation' has to be performed in order to view the Concrete Design Result on the screen.

Note 2

The design results for column and wall members can be checked by load combinations. On the other hand, the design results for beam members can be checked only for the most unfavorable load combination. Because in midas Gen, design results for beam members for each load combination are not stored.

Display the number of tie legs for each direction.

From the Main Menu select Design > Concrete Design Result.

Load Cases/Combinations

Select the desired load case, load combination or envelope.

Click to the right to enter, add or modify load combinations (refer to Load Cases/Combinations).

Ratio by Components

Select the desired component of the design results from the following:

Axial: Axial strength ratio component

Shear-y: Shear strength ratio component in the direction of the

strong axis

Shear-z: Shear strength ratio component in the direction of the weak

axis

Bend-y: Bending strength ratio component due to moment about the

strong axis

Bend-z: Bending strength ratio component due to moment about the

weak axis

Combined: Maximum combined stress component ratio

Note.
The Combined option needs to be selected to check the reinforcing information of the design result.

Combined for beam = max [bending ratio(M_Ed/M_Rd), shear ratio(V_Ed/V_Rd)]

                                        Combined for column = max [axial ratio(N_Ed/N_Rd), moment
                                        ratio(M_Rd/M_Rd)]
                                       where:
                                       (M_Ed/M_Rd) = √(M_Edy²+M_Edz²) / √(M_Rdy²+M_Rdz²).

Note
Contour Range Max/Min values can be larger than the max/min output values.

If the Contour Range values exceed the output values, they are entered at Rank 0 and Rank 11.

Legend Position: Select the position of the legend in the output window

Rank Value Type: Specify a type of values in the Legend and the number of decimal points.

Values

Display the selected design result components by means of numerical values.

The font and color of the numbers can be controlled in Display Option.

Note

When checking the Design Result on the screen, if the design result exceeds the limit value, the text is marked in red color.

Decimal Points: Specify decimal points of the displayed numbers

Exp.: Option to express numerical values in exponents

Min & Max: Display the minimum and maximum values

Abs Max: Display the absolute maximum value

Max: Display only the maximum value

Min: Display only the minimum value

Limit Scale(%): S

et the screen limits for displaying design results relative to the maximum or minimum value

Note
The default Decimal Points can be controlled in "Preferences".

Reinforcement

Reinforcing results are produced. (Refer to Note.)

Rebar: Reinforcing bar diameter and spacing

Area: Required reinforcing steel area

Ratio:

For Main Rebar:

Ratio of provided main reinforcing steel area to sectional area.

Sectional area for tension rebar = (width of section * effective depth (d) of section).

Sectional area for compression rebar = (width of section * total depth (D or H) of section).

Note.

Software takes higher area of top and bottom rebar as the tension rebar area for calculating the reinforcement ratio.

For Shear Reinforcement:

Ratio of provided shear reinforcing steel per unit spacing to sectional width.

Display: Select the types of elements for which design reinforcing information will be displayed.

Output Component: Select the component to be displayed.

Ratio of Axial Stress

Main Rebar: Main rebar design result

Shear Reinforcement: Shear reinforcement design result

Column Section Size: Display of column section sizes can be scaled.

Value Option: Specify the number of decimal points for displayed values.

Note. Display of reinforcement

From the V600 of MIDAS/Gen, reinforcing information such as rebar diameter, rebar spacing and required reinforcing steel area can be checked in 'Concrete / SRC Design Result'.

1) When 'Rebar' is selected in Reinforcement

2) When 'Area' is selected in Reinforcement

1. Rebar information for beams

Design results for the beam ① in the Figs. 1) & 2) above are produced.

3) Beam design results (Graphic)

The rebar diameter and spacing denoted by A in Fig. 3) are produced when 'Rebar' is selected in the Reinforcement option in Fig. 1). If 'Area' is selected, the required reinforcing steel areas are produced as denoted by B in Fig. 3).

2. Rebar information for columns

Design results for the column ② in the Figs. 1) & 2) above are produced.

4) Column design results (Graphic)

5) Reinforcing information of column by selecting 'Rebar'

6) Reinforcing information of column by selecting 'Area'

The following outlines the reinforcing information in Figs. 5) & 6):

a. (Uc): Ratio of axial stress of the column (N/(fc' X Ag))

b. (As-corner): Number of corner rebars & rebar area

Ex.) 4-#7 = 4 X 0.6 = 2.4 in2

c & d (Asy, Asz): Number of rebars and rebar area on a single side

e. (Asv): Tie (shear) reinforcing spacing of column, Sc and rebar area within the spacing

Based on the reinforcing information noted at b, c & d above, the total number of rebars then becomes,

b+ ((c - 2) + (d - 2)) X 2 = 4 + ((6 - 2) + (7 - 2)) X 2 = 22

The number of rebars on one side (Asz)=5

22-6-#7 (See C in Fig. 4)

3. Rebar information for walls

Design results for the wall ① in the Figs. 7) & 8) are produced.
