Beams Tab

In this tab, the list of beam dimensions and rebar is given as a table.

Specifications

DS

It is the rebae fixing column. If marked, the rebar is fixed. DS is automatically marked when changes are made in beam rebar, and when concrete is made, the beam rebar also remains constant. If DS is not marked, when concrete is made, beam rebars are determined again according to rebar selection conditions.

ID

It is the name of the beam in the plan. (K1, K101, K10 etc.) In case of negativity, the term related to negativity is added next to the name. Like K101 (M).

Story

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

B, H

It is the width and height of the beam, respectively. You can change the dimensions by double clicking in the B and H cells. When the size is changed, the beam rebar calculation is made for that beam according to the changed dimensions.

L-upper

It is the value in terms of number and diameter of the rebar located on the left support section of the beam. You can make changes by double-clicking the cell.

L-under

It is the value of the rebar under the left support section of the beam in terms of number and diameter. You can make changes by double-clicking the cell.

Concrete Configuration Tab

In the reinforced concrete configuration tab, the beam drawing appears. You can shift the drawing left and right by holding down the left mouse button.

When you left click on the beam text indicating the name of the beam (K1 25/50 etc.), a dialog showing the beam reinforcements opens. In this dialog, the reinforcement diameter and / or quantity of the beam can be changed.

The same can be done by clicking on any reinforcement text value on the drawing. In this case, a dialog opens in which only the clicked reinforcement will be changed.

Update neighboring supports: This option is important if the reinforcement being replaced is a reinforcement that is shared with neighboring beams. If the option is selected, the reinforcement in the adjacent support is automatically changed.

In the reinforced concrete configuration, especially the green and / or red circles that appear on the supports of continuous beams determine where the beam reinforcements are to be cut.

If the circle is green, the reinforcement is continued to the next span. If the circle is red, the reinforcement is cut at the support.

Circles are turned into red and / or green (reinforcement passes / does not pass) by clicking with the mouse. According to the reinforcement cutting status, the reinforcement arrangement is made automatically, excess or missing reinforcements can be viewed on the screen. Missing reinforcements are transmitted to the user in red.

Miter: If it is green, it means that the reinforcement will be cut with a set square. Red means that the reinforcement will be left straight or continue to the adjacent beam.

Partial transition: Partial transition is active in green, inactive in red. This option, which is set for continuous but different beams, regulates whether a certain proportion of the reinforcement will be transferred to the other beam. In two continuous beams of different widths, if this option is selected, the reinforcement transition is arranged by taking into account the ratio found from the division of the width values ​​of the adjacent beams. For example, let the width of the 1st beam 50 cm and the width of the 2nd beam 25 cm. 25/50 = 0.5 ratio. The number of reinforcement, for example, is 4 flat reinforcement 2 pieces of reinforcement will make partial transition, and 2 pieces of reinforcement will be cut with a square.

Combine: If the beam is continuous, the continuous beams automatically have the same continuity and the reinforcement is drawn continuously up to the maximum reinforcement length value (12 meters). So this option is automatically green. If the option is deselected (made red), the canceled beam will not be drawn continuously, but detached from the adjacent beam at the common support.

Vd: It is the shear force calculated under the combined effect of the vertical loads and earthquake multiplied by the load coefficients.
Mpi, Mpj: The left and right end are moments of carrying power. In beams of normal ductility level;
Vd value is taken directly as Ve.

Vmax

And if - Vdy> = 0.5 Vd then Vc = 0 is taken.

Vr = Vc + Vw The
contribution of the battery to the shear force is never included in the shear calculation.

If And> Vmax or Ve> Vr, the cross section is insufficient.

And Asw / s is calculated from the formula of = (Asw / s) * fywd * d + 0.8 Vc. S is accepted as 1 meter.

 And if - Vdy> = 0.5 Vd then Vc = 0 is taken.

The asw / s value is never allowed to be less than 0.3 (fctd / fywd) * bw.
