Structural material

Select the static material to be used in the column element from the list. Static material can be defined as a reinforced concrete element under Materials in Building Tree.

Defined section parameters

The section and geometric properties of the element are determined automatically and these are the values ​​in accordance with the regulations. However, if you want to change the element section properties, mark this line and give the relevant values ​​to the program. The program automatically calculates zero values ​​and accepts non-zero entries as much as the entered value.

2 axis moment of inertia

The element is the minor moment of inertia. I = b ³ h / 12
For example, in a 50/25 rectangular column, the moment of inertia of the 2 axes is calculated as 25.25.25.50 / 12 = 65104 cm ⁴.

3 axis moment of inertia

The element is the major moment of inertia. I = bh ³ /12 50/25 For example, in a column three axis rectangular moment of inertia 50.50.50.25 / 12 = 260416 cm ⁴ is calculated as.

Torsional moment of inertia

It is the moment of inertia that defines the torsional stiffness of the element.

Cross-sectional area

It is the cross-sectional area value of the element. For example, in a 50/25 rectangular column, the cross section area of ​​the element is 50.25 = 1250 cm ² .

Cutting area in 2 direction

The element is the cutting area in the minor direction. Cutting area = 5/6. b. d For example, in a 50/25 rectangular column, 5 / 6.50.25 = 1041 cm2

Cutting area in 2 direction

The element is the cutting area in the major direction.
Cutting area = 5/6 b d

Rebar coupling

This option is activated if it is desired to make anchoring reinforcement attachment instead of lap joint in the columns. The confounding value is entered in the staggering distance box for the coupling application.

Column free span length (ln) calculation

The column free height is determined automatically according to the geometry of the elements. In some special cases, the desired clear opening value can be entered manually by using the defined option.

Rebar splice

Rebar splice is found automatically with the let the program decide the splice location option. If desired, the rebar splice can be made in the middle section or bottom. The delta amount is entered for the splice location.

Circular column stirrup type

When the stirrup is selected, only stirrup design will be made in the circle column. When the stirrup - crosstie is chosen, it means that both stirrup design will be made in the circle column and the vertical reinforcements will be connected to each other with cryst.

Bottom end embracement region length

Column winding zones are found automatically according to the matters specified in the earthquake regulations. Stirrup tightening is made in the hugging areas. When the find a program option is selected, automatic adjustment is made to the regulation conditions. However, it may be desirable to arrange the length of the lower confinement zone at a different value, for example, for basements or columns to which high walls are connected. In this case, by entering the value in the Defined line, the lower end of the column can be formed in the desired length. If the length value gives the column length, the stirrup tightening is done in the column completely.

Lateral reinforcement leg counts

The number of lateral reinforcement legs is found automatically. In some special cases, the desired value can be entered manually in the box by using the defined option.

Connection to foundation

Foundation connections are found automatically. If desired, one of the options "Create separate dowel bars or use main bars" is selected.

Sub basement level elevation

The sub-basement level elevation is found automatically. In some special cases, the desired sub basement level elevation can be entered manually in the box by using the user defined option.

Multiple stirrup design

Image Removed

Image Added

If it is checked, it means that the program can design double stirrups in the column. Double stirrup design is determined automatically depending on the size of the column and the number of vertical reinforcements. In cases where a double stirrup design is not made in the column, a tie-break design is made according to the regulations.

This column is a support for a cantilever slab

This option can be selected if the column console is the support of a floor. Otherwise, it should not be marked.

Always detail outside in the app

When the option is selected, the column is not detailed on-site in the column application plan, instead the column is drawn as a scaled plan view. The detail expansion is also shown on the sheet edge.

Use fiber reinforced polymer

Image Modified

In columns that will be reinforced with fiber polymer, Fiber polymer properties are set by checking this option. Reinforcement is made by selecting one of the fiber polymers defined in the Fiber Reinforced Polymer Library and the count of wrap.

Plastic hinge locations for pushover analysis

Image Modified

For pushover analysis, theplastic hinge can be identified automatically or manually.

Corrosion factor

Image Modified

It is a ratio used in building performance analysis. With the ratio written on this line, the wear occurring in the existing structures and reinforcements exposed to the corrosion conditions specified in the earthquake regulation can be taken into account in the performance calculation of the structure. The value defined in this row is multiplied with the existing reinforcement areas and the value found at the result of multiplication is considered as the reinforcement area.

Steel yield stress factor

Image Modified

It is used to reduce the steel yield stress of the elements. The value entered in this row is multiplied by the steel yield value of the element.

Conforming transverse reinforcement

Image Modified

If there is stirrup tightening at the upper and lower ends of the column of the existing structure, this option is selected. When this option is selected, it is assumed that the columns have confined concrete behavior. To define the hook angle of the stirrups in the tightening area of ​​the existing column, one of the 90˚ or 135˚ hook options should be selected.
