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 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 steels opens. In this dialog, the rebar diameter and/or quantity of the beam can be changed.

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

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

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

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

Partial pass: Partial pass is active in green, inactive in red. This option, which is set for continuous but different beams, regulates whether a certain proportion of the rebar will be transferred to the other beam. In two continuous beams of different widths, if this option is selected, the rebar pass 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 rebar, for example, is 4 flat rebar 2 pieces of rebar will make partial pass, and 2 pieces of rebar 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 rebar 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.

Reinforcement Areas Tab

Specifications

Accessories section (existing - required - diffrence)

At the left support of the beam, upper and lower; in the middle; clearance and mounting; in the right bracket; The sum of the available / required and surplus reinforcement areas is given as top and bottom. Just below, the loading combination of the reinforcement calculation and the moment values ​​of that combination are also written.

Right moment0: At ​​the beam right support, the moment zero point is the distance from the right end of the beam. The value can be changed if desired. In the beam details, the break distance of the battery is taken as the value written here.

Design shear force (Ve)

It is the design shear force used in stirrup calculation.  

In beams of high ductility level;

Vd value is taken directly as Ve.

Vmax

Vmax = 0.22 fcd bw d
Ve <= Vmax or Ve <= Vr otherwise the section is insufficient. The program will then warn of insufficient section for the beam in question.

It is the shear force that creates the oblique crack.
Vcr: 0.65 fctd bw d

Vc

It is the shear force carried by concrete.
And if - Vdy> = 0.5 Vd then Vc = 0 is taken.
Otherwise, Vc = 0.8 Vcr is calculated.
Vd: It is the calculated shear force under the combined effect of vertical loads and earthquake loads multiplied by load factors.

Vr

It is the maximum cutting force value that the section can carry. The design shear force Ve used in stirrup calculation is not allowed to exceed Vr.

The method followed in the calculation of Vr:
Vw: It is the contribution of shear reinforcement to the shear strength.
Vw = (Asw / s) * fywd * d
Vr = Vc + Vw The
contribution of the battery to the shear force is never included in the shear calculation.

Loading

And the loading that gives its value is the name of the combination.

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.
