Interlock and Overlap Lengths

[qwerty]

Dear friends, Questions are asked in terms of the Program. Column: 1- How is the clamping length of the column shoots coming out of the foundation within the foundation calculated? Beam: 2- Is overlapping made on the beam? The regulation did not allow for towing areas, if so, where is it done? 3- Is "lb=0.12*fyd/fcd*diameter" used as Straight Overlap length in the beam? or "1.lb= (0,12*fyd/fcd*dia)*1.4" is used according to Position-I. That is, is the Position-I formula applied? 4- When bending of the beam reinforcement occurs (inside the column or when it encounters a beam of different height, that is, in the case of TDY 3.4.3.1), is "lb=0,12*fyd/fcd*diameter" used as the Overlap/Clock length? or "lb= (0,12*fyd/fcd*dia)*1.4" is used according to Position-I. 5- TDY2007-3.4.3.1.(b) states, "In case the beams join the columns from both sides, the sub-beam reinforcements shall be extended at least as much as the clamping length given in TS-500, not less than 50 ft from the column face adjacent to the opening." Does the program implement this? 6- Beam parameters / Rebar transitions / Extend upper reinforcement to adjacent opening: ln/xxx / Extend lower reinforcement to adjacent opening: ln/xxx Is it necessary to mark and enter values for TDY2007 and TS500? Is it taken into account in the calculation of clamping and overlapping lengths when it is marked and a value is entered? Should it be taken? 7- Does it make Overlaps as desired by TS500? 8- In the addition (overlap) of the tensile reinforcement, Lo=alfa*lb alfa=1+0.5r r: It is defined as the ratio of the reinforcement added in the same section to the total reinforcement. Does the program calculate alpha? Where does he use the formula lo=alpha*lb? 9-General Reinforced Concrete settings / Coupling Reinforcement Attachment / When the Use coupling reinforcement attachment when equal and larger is checked, what will this affect (In Beam, Column, Foundation, etc.)? Does it reflect in my drawing? General: 10- Is there anything that the program does not do about clamping and overlapping length, but the user should do? 11- What would be more appropriate to intervene before and after analysis, before and after drawing in the parameters of the program related to clamping and overlapping length? 12- TS500-9.1.2.1 "In cases where the concrete cover is less than the diameter of the reinforcement or the net distance between the reinforcement bars in the same row is less than one and a half times the diameter of the reinforcement, the clamping lengths calculated from Equation 9.1 should be multiplied by 1.2." says. Does the program pay attention to this situation?

1- How is the interlocking length of the column shoots coming out of the foundation in the foundation calculated?

It is always controlled as 1.5lb. It can be intervened from the General Reinforced Concrete Parameters. [ quote="qwerty":3eserikz"] Beam: 2- Is there an overlap on the beam? The regulation did not allow for tension zones, if so, where is it done?[/quote] Overlap is made on the upper reinforcement exceeding 12 meters in beams. There is no overlapping on the bottom reinforcement.

3- Is "lb=0.12*fyd/fcd*diameter" used as Straight Overlap length in the beam? or " according to Position-I" Is 1.4lb= (0.12*fyd/fcd*diameter)*1.4" being used. Is the I formula applied?

In the formula "lb=0,12*fyd/fcd" it is fctd, not fcd. Program default overlap length is 50fi. It can be intervened from General Reinforced Concrete Parameters. Position-I formula is not applied.

4- Is "lb=0,12*fyd/fcd*diameter" as Overlay/Clock length when the beam reinforcement occurs bending (inside the column or when it encounters beams at different heights, that is, in the case of TDY 3.4.3.1)? used? or according to Position-I "1.4lb= (0,12*fyd/fcd*dia)*1 Is ,4" used.

Controlling TDY 3.4.3.1 depends on user selection in beam parameters. If this option is not checked, it is made up to the miter (Beam Height-Concrete Cover). Position 1 - Position 2 check is not performed.

5- TDY2007-3.4.3.1.(b) states "In case of joining of beams to columns from both sides, the sub-beam reinforcements shall be extended by at least the clamping length given in TS-500, not less than 50 ft from the column face adjacent to the opening." . Does the program implement this?

Yes, it does.

6- Beam parameters / Rebar transitions / Extend upper reinforcements to adjacent opening: ln/xxx / Extend lower reinforcements to adjacent opening: ln/xxx Is it necessary to mark and enter values in terms of TDY2007 and TS500? Is it taken into account in the calculation of clamping and overlapping lengths when it is marked and a value is entered? Should it be taken?

For TDY2007 and TS500, it is not necessary to change the values. If the value is entered, it is taken into account in the beam expansion.

7- Does it make Overlays staggered as the TS500 wants

Not done.

8-In the addition (overlap) of tensile reinforcement Lo=alfa*lb alfa=1+0.5r r: defined as the ratio of the reinforcement added in the same section to the total reinforcement. Does the program calculate alpha? Where does he use the formula lo=alpha*lb?

Not used. The program default overlay size is 50fi. It can be intervened from the General Reinforced Concrete Parameters.

9-General Reinforced Concrete settings / Coupling Reinforcement Supplement / When the Use sleeved rebar attachment when equal and larger is checked, what does this affect (In Beam, Column, Foundation, etc.) ? Will it be reflected in the drawing?

Sleeve attachment can only be made in the column. It is reflected in the drawing. (Changes in reinforcement lengths are reflected in the drawing, the couplers are not shown.)

10- Is there anything that the program about clamping and overlapping length does not do, but the user should do?

Normally there is not. Overlay and clamping lengths are parametric. In different situations, you can look at the drawing and decide for yourself.

11- What would be more appropriate to intervene before and after analysis, before and after drawing, in the parameters of the program related to clamping and overlapping length?

This question is the summary of the questions you asked above. The answers are given above. In different situations, you can look at the drawing and decide for yourself.

12- TS500-9.1.2.1 "In cases where the concrete cover is less than the diameter of the reinforcement or the net distance between the reinforcement bars in the same row is less than one and a half times the diameter of the reinforcement, the clamping lengths calculated from Equation 9.1 should be increased by multiplying by 1.2." says. Does the program pay attention to this situation?

It is not checked. Concrete cover value is under user control. It can be changed in parameters.

1) Apart from the calculation and control of a+b>=lb in the parts within the foundation, are a>=0.4lb and b>=12*fi controls also made? 2) In case of TDY 3.4.3.1, does it calculate in lb according to the formula in TS500 or does it calculate according to the value written for the minimum reinforcement overlap length in the General reinforced concrete parameters (default value is 50 fi). 3) When I enter ln/0.00 for the passage of the Upper and Lower reinforcements, does the neighbor make the extension to the opening? If it does when I enter ln/0.00, how does it extend to the adjacent opening according to the upper reinforcement? If it does when I enter ln/0.00, how does it extend to the adjacent opening according to the sub-reinforcement? For example, I entered ln/4 for the Sub-Sonata part, does the program choose overlay length (lb, 50fi) and ln/4 compared to each other? 4) For example, when we enter the value of 18fi, will all column reinforcements with a diameter of 18 and above be added as sleeves? Naturally, there will be no overlapping. Will it also make overlay calculation and drawing for reinforcements with a diameter less than 18?

1)Are a>=0.4lb and b>=12*fi checks are also made in addition to the calculation and control of a+b>=lb in the parts within the foundation??

In parts, as I wrote an answer to your previous question, it is a+b>=1.5lb depending on the parameter a depends on the height of the foundation b>=12*fi is not checked, b>=30 is taken a>=0.4lb for column sprouts There is no control, this is valid for the beam square you have written. TDY 2007 Figure 3.2 is valid for the column.

2) In the case of TDY 3.4.3.1, it calculates in lbs according to the formula in TS500 or the minimum reinforcement overlap length written for the general reinforced concrete parameters (default Does the value calculate according to the fi) value?

In case of TDY 3.4.3.1, Lb given in TS500 is used.

3) When I enter ln/0.00 for the passage of Upper and Lower reinforcement, does it make the extension to the neighboring opening? ln/ If it does when I enter 0.00 How does it extend the adjacent opening according to the upper reinforcement? How does it extend to the adjacent span? For example, I entered ln/4 for the lower sonata part, does the program make selections by comparing the overlap length (lb, 50fi) and ln/4 relative to each other?

If Ln /zero is entered instead of Ln/4 for the upper reinforcement, it will be extended by 50fi( not dependent on 50fi in general reinforced concrete settings). If Ln/0 is entered for the bottom reinforcement, TDY is performed according to figure 3.7 (lb, 50fi). If ln/4 is entered, the higher value is used.

4) For example, when we enter the value of 18fi, will all column reinforcements with a diameter of 18 and above be added as sleeves? Naturally, there will be no overlapping. Will it also make overlap calculation and drawing for reinforcements with a diameter less than 18?

In column settings, in which columns the sleeve will be applied and the offset distance can be given. In General Reinforced Concrete Settings, the minimum reinforcement diameter for the sleeve can be selected.
