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

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: Steel reinforcement ratio

 

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 ич 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 иш 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 ич in the Figs. 7) & 8) are produced.

 

7) Reinforcing information of wall by selecting 'Rebar'

 

8) Reinforcing information of column by selecting 'Area'

 

The following outlines the reinforcing information in Figs. 7) & 8):

 

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

 

b. (V)8-#4@16": Number of vertical rebars and spacing or vertical reinforcing steel area per unit length (in2/in)        

 

c. (E)12-#3@6": Number of end rebars and spacing or total amount of reinforcing steel (in2)  

 

d. (H)#3@11": Number of horizontal rebars and spacing or horizontal reinforcing steel area per unit length (in2/in)     

 

 

Output Section Location(Beam)

 

Check RC member design results by sectional locations. It can be used only when "Values" of "Type of Display" is selected.

 

I, Center, J: Represent the RC beam member's sectional locations. The user can not select the locations. It is automatically selected following the selection of "Max" or "All".

 

Max: Maximum values appear at every RC beam member.

 

All: Values appear at each location of RC beam members.

 

 

 : Apply the entered values to the selected members.

 

 : Close the Entry Dialog Bar.
