Specifications

DS

It is the rebar fixing column. If marked, the rebars are fixed. When changes are made to the slab rebars, the DS is automatically marked and the rebars remain fixed even if the slab is made of concrete. If the 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. (RD1, RD2, RD10 etc.) In case of negativity, the term related to negativity is added next to the name of the plate. R101 (Min) etc will appear.

Thickness

The thickness of the raft foundation appears in this cell.

Story

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

N

It is the number of concrete calculation axis. (1,2,3,4 etc.) Since there can be more than one concrete calculation axis on the same plate, the numbers of the calculation axes are followed from the N column.

LUnder aux

The diameter and the spacing in cm of the additional rebar calculated under 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 the spacing in cm of the rebar located above the slab section in the relevant concrete calculation axis. The diameter and range of the rebar can be changed by double clicking on it.

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 range of the rebar can be changed by double clicking on it.

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 range of the rebar can be changed by double clicking on it.

RUnder aux

It is the diameter and the interval in cm of the additional rebar calculated under 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

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 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.

Concrete fck

The characteristic of concrete is its compressive strength.

Concrete fcd

The characteristic calculation of concrete is its compressive strength.

Concrete fctd

The characteristic calculation of concrete is its tensile strength.

Rebar fyk

Reinforcement is the yield strength of rebar.

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.

Auxilary 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
