Select

Selects the object on the line with the cursor. When the concrete dialog is closed, you can take action for the selected element.

Previous

The cursor moves to the previous line.

Next

The cursor goes to the next line.

Filter

It is used to define certain conditions and filter only the elements that satisfy that condition.

Ok

It saves the changes made and closes the dialog.

Cancel

Closes the dialog without saving the changes made.

Slabs Tab

Slabs are listed according to the concrete account axis. Since there can be more than one concrete calculation axis in a slab, the concrete results will be listed with as many lines as the number of calculation axes available in the slab.

Specifications

DS

It is the rebar fixing column. If marked, the rebars are fixed. DS is automatically marked when changes are made to the slab rebars and the rebars remain fixed even if the slab is made of concrete. If DS is not marked, the rebars are determined again after the analysis according to the rebar selection conditions.

ID

It is the name of the story that appears in the plan. With the dialog open, double click the name cell to find the slab in the plan.

(D1, D2, D10 etc.) In case of negativity, a term about negativity is added next to the name of the record. For example, D101 (Min) will appear.

Thickness

The thickness of the slab appears in this cell.

Story

The name of the story where the slab is located appears in this cell.

N

It is the number of concrete calculation axis. (1,2,3,4 etc.) There can be more than one concrete calculation axis in the same slab. Slabs with the same name appear one under the other with the numbers of different account axes. From the N column, you can follow the direction of the calculation axis.

L upper aux

The diameter and the spacing in cm of the additional rebar calculated above the left support section on the relevant concrete calculation axis are shown. If double clicked on the cell, the diameter and spacing of the rebar can be changed.

Upper straight

It is the diameter and interval in cm of the rebar located above the slab section in the relevant concrete calculation axis. The diameter and spacing of the rebar can be changed by double clicking on the cell.

Bent-up

It is the diameter and interval in cm of the pleat rebar with slab on the relevant concrete calculation axis. The diameter and spacing of the rebar can be changed by double clicking on the cell.

Under straight

It is the diameter and interval in cm of the rebar located under the slab section on the relevant concrete calculation axis. The diameter and spacing of the rebar can be changed by double clicking on the cell.

R upper aux

It is the diameter and interval in cm of the additional rebar calculated above the right support section in the relevant concrete calculation axis. The diameter and spacing of the rebar can be changed by double clicking on the cell.

Moments - Reinforcement Areas Tab

Specifications

Left (upper)

Defines the upper part of the section belonging to the left support of the slab for the investigated concrete calculation axis.

Span (under)

It defines the lower part of the section in the slab opening in the analyzed concrete calculation axis.

Span (upper)

It defines the upper part of the section in the slab opening in the analyzed reinforced concrete calculation axis.

Right (upper)

It defines the upper part of the section belonging to the right support of the slab in the analyzed concrete calculation axis.

Moment

The design moment value that is taken as basis in concrete design is given.

As (Calculated)

It is the area of rebar found for a width of 100 centimeters from the design moment.

As (Required)

It is the rebar area calculated from the design moment and the one that is greater than the rebar area to be placed as per the regulation.

As (Existing)

It is the total rebar area value available in the section after the rebar selection.

Load combination

You can examine the moment diagram by choosing the combination you want from the combination list.

Structural material

Shows the structural material of the slab.

fck

The characteristic of concrete is its compressive strength.

fcd

The characteristic calculation of concrete is its compressive strength.

fctd

The characteristic calculation of concrete is its tensile strength.

Rebar fyk

Reinforcement is the yield strength of rebar.

fyd

It is the calculation strength of rebar steel.

Moment diagram

The moment diagram according to the selected combination is displayed on the analyzed calculation axis. When you move the mouse over the moment diagram, the position of the cursor on the diagram is shown. X represents the Y moment value for the left distance.

Extra Reinforcements Tab

When flat rebar design is made on top and bottom for beams and non-beam slabs, the additional diameter and number are specified to cover the entire slab system. If the rebar calculation axis is selected as top and bottom straight, the program automatically creates additional zones on the supports required as a result of the plate analysis. After analysis and concrete design, the diameter and number of additional rebars are determined and listed on this tab.

In the tab, detailed information about the additional rebar is given in the table, and in the schematic plan view, the information about the area of the additional rebar is given. Blue areas represent upper additional rebar zones, red areas represent lower additional rebar zones.

Specifications
