Fill slab region If the option is selected, the area within the slab boundaries will be shown painted in the plan. |
Fill color The color in which the inside of the slab will be painted is adjusted. Click on the color box with the left mouse button and slide the mouse cursor over the opened color palette. When the desired color is reached, the key is released. The color box turns into the selected color. If the color box is clicked with the shift key on the keyboard, the pen thickness of the relevant color can be adjusted. |
Draw reference line of inclined slab It is used to show the reference axis of the floors (inclined slabs) with an angle different from zero degrees with the slab in the plan. |
Thickness The slab height is entered. The slab starts from the floor ceiling and hangs down to the given height. If the slab height is increased, the slab becomes thicker downwards. |
Elevation The slab level is entered. When the elevation is zero, the slab top surface is flush with the floor ceiling. If a positive value is entered, the slab rises from the floor ceiling, if a negative value is entered, it falls under the story ceiling. Negative value is entered to obtain low slab. |
Use composite material Composite materials allow the slab to be drawn in a different material view in cross-section. If checked, it allows the use of materials defined in the "Composite Material" editor. After the row is marked, one of the composite materials in the list below is selected with the left mouse button. Changes the appearance of the slab in section according to the selected composite material. |

Rib offset (D2) It is the clean distance between two ribs. |
Rib width (W) It is the width of the rib. |
Rib height (H) It is the height of the rib. |
Structural Tab
Specifications |
|---|
Structural material Select the structural material to be used in the element from the list. Structural material can be defined as a reinforced concrete element under Materials in Building Tree. |
Finite element width Enter the maximum finite element width to be taken as basis in the slab calculation. The program performs slab analysis by dividing tiles into trapezoidal finite elements. Finite element width is automatically adjusted according to the slab shape, provided that it does not exceed the value entered in this row. |
Moment calculation angle When this value is left zero, the slab axes are taken as 0 degrees in the 1st direction and 90 degrees in the 2nd direction during the slab analysis. In a rotated structure, the moment calculation angle is also refreshed automatically. The value can be changed when slab analysis is desired to be performed according to the axis at different angles. 1. The structure is defined parallel to the x axis. When the torque angle is 0 degrees, the following moment diagram is obtained. 2. If the structure is rotated 45 degrees and the moment angle is given 45 degrees, the same results as 1 are obtained. 3. If the moment angle is left zero in a structure that is entered as 45 degrees, results different from 1 and 2 will be obtained. |
Dynamic live load multiplier While calculating the total weight of the building, the live load value coming from the relevant slab is taken into account by multiplying it with the value entered in the box. In the earthquake load calculation, element design results change as the total mass of the building will change. However, this multiplier does not change the live load value on the slab. |
Create concrete calculation lines When the slab is placed, this option can be selected to automatically create the reinforced concrete calculation axis for the slab. In this case, two horizontal and vertical reinforced concrete calculation axis are created in the middle of the floor in each defined floor. If the option is not selected, the user must define the reinforced concrete calculation axis using the "reinforced concrete calculation axis" command. |
Draw concrete calculation lines If it is wanted to show the reinforced concrete calculation axis showing the direction in which the slab reinforced concrete will be made, it is marked. This representation is for informational purposes only and is not drawn in the formwork and / or reinforcement plans. |
Rigid diaphragm index Rigid diaphragms are automatically detected by the program according to the presence / absence of slab on any slab. These parameters change the rigid diaphragm conditions on a slab basis. The changes made affect the analysis. Rigid diaphragm index It is the number that groups rigid diaphragms. For example, in projects with a single rigid diaphragm, this value is 1 for all floors. In systems with different rigid diaphragms, diaphragms will be indexed as 2, 3 etc. Create automatic diaphragm When the option is selected, the slab will be included in the rigid diaphragm index determined according to the rigid diaphragm index. All slabs with the same index number will be in the same rigid diaphragm. Do not connect to story diaphragm When the option is checked, the slab will not be found on the rigid diaphragm. Create automatic diaphragm regardless of connectivity Regardless of the position of the slab when the option is selected, slabs according to the number written in the rigid diaphragm index will be accepted within the same rigid diaphragm system. For example, this option may be needed in systems with two towers with space in between. |
Reinforcement chair By selecting the option, the reinforcement chair is defined for the slab. |
Diameter The diameter of the reinforcement chair is entered. |
Count The number of reinforcement chair per square meter is entered. |
Reinforcement chair The dimensions of the reinforcement chair are entered. The height of the reinforcement chair is found by subtracting the concrete slab height. The negative or positive value to be written to the height is added to the height value calculated by the program. |
Deflection Tab
TS500 Deflection limits: Give deflection control upper limits. Values taken from TS500. If the "Always check deflection condition" option is selected, the instantaneous and temporal deflection control is performed on the slabs even if the "deflection condition is a height condition that does not require deflection control" is checked.
Mesh Wire Tab
Specifications |
|---|
Use mesh wire Check the option to design ready reinforcement on the object. |
Auto selected mesh wire Check this option if you want to design the mesh wire selection as the choice made by the program as a result of the analysis. The program will use the most suitable mesh wire according to the calculation. |
Use selected mesh wire Regardless of the analysis result, if you want the program to use the reinforcement you have provided as mesh wire, check this option. Next, select mesh wire from the list to use under. |
Under For user-defined mesh wire, select the reinforcement to be used under the section. |
Building Components
Add Building Components: Assigns the projected building materials to the object for detailed building components metrics.
Click on the building components button.
The Component Selection dialog will open.
In this dialog, click on the folder related to the material from the list on the left. Click on the material you want to use.
Set the parameters on the right.
Click the OK button. The "Component Selection" dialog will be closed. A summary line of the material will appear in the Building Components tab. More than one material assignment to an object can be done this way.
In the usage section
No modification: The amount of material to be assigned for the object in question is marked when it is desired to be used in the size that was previously specified in the material definition.
Percentage: This line is marked when it is desired to be used with the percentage of the amount previously determined in the material definition, as much as the value entered in the "Value 1" line in the same dialog. For example, if the material quantity is 70, if the line “Value 1” says 40, it means the material amount will be used up to 40 * 70%.
Override: This line is marked so that the quantity entered in the “Value 1” line in the same dialog will be used instead of the quantity previously determined in the material definition.
Multiplier: This line is marked in order to use the value found at the end of the multiplication of the value entered in the "Value 1" line in the same dialog with the amount previously determined in the material definition.
Fraction: This line is marked so that the amount determined in the material definition before will be used as the fraction value created by the values entered in the "Value 1" and "Value 2" lines in the same dialog. "Value 1" is the denominator "Value 2" is the denominator.
Proportional to: It is determined to what scale-area, circumference, length etc.-, region-side area, top, edge etc.- the material will be proportioned to. The content of the proportional list box is automatically determined according to the object and the size of the material. For example, a different list will be created if an operation is made for the column, a different list will be created for the library, a different list for the volume, and a different list for the field.
The lines that appear in the Proportion list according to the slab object and material size are as follows:
