Column Strip Design

 

 

 

Produce the column strip design results considering the unbalanced moment.

 

Note
In order to use this function, KDS41 30 :2018 or KCI-USD12  must be selected in Design > Concrete Design Parameter > Design Code.

 

 

 

 From the Main Menu select Design > Design > Meshed Slab/Wall/Shell Design > Column Strip Design.

 

 

 

 

Load Combinations

 

Select a desired load case or load combination.

Click  to the right to enter new or modify existing load combinations. (Refer to "Static Load Cases / Combinations")

 

     

     Force Options

 

 

Element: Display the contour using the internal forces calculated at each node of an element.

 

Avg. Nodal: Display the contour using the average internal nodal forces of the contiguous elements sharing the common nodes.

 

Note

Avg Nodal does not consider the simultaneity for the load case in which maximum member forces are displayed about all elements such as Moving Load Case, Settlement Load Case and Time History Load Case.

 

 

 

Type of Display

 

 Define the type of display as follows:

 

 

Components

 

Rebar

Display the column strip reinforcement status by diameter and spacing.

 

Output Contents :  Top bar (End : Center : End),  Bottom bar (End : Center : End)

 

Middle Strip

If you check the Slab Design Result checkbox in the lower part of the dialog, you can check the reinforcement result of middle strip slab.

 

  - For the design of the middle strip slab, only the slab elements set as Sub-Domain are calculated.

  - Top bar: Calculate the most unfavorable top bar  including the Column Strip area.

  - Bottom bar: Calculates the most unfavorable bottom bar, excluding the Column Strip area.

  - If the bottom bar of middle strip  requires both Basic Rebar and Add Rebar, it is output in two lines.

    (Refer to the figure below)

 

 

As (m^2/m)

Display the area of the required reinforcement.

 

 

Resistance Ratio

Display the ratio of the design strength

 

Bending Moment Diagram

Display the bending moment diagram of the column strip

 

Unbalanced Moment

Display the unbalance moment of the column strip, and the strength ratio considering the unbalance moment (KCI2012 7.12.7 Commentary) at the node position of the column.
