Hi Everyone, I am designing a be

Hi Everyone, I am designing a be

Hi Everyone, I am designing a be

(OP)
Hi Everyone,

I am designing a beam for that I know that the lap splices for bottom bars shall be given after a distance '2D' from the face of column. But if I use this, the lap comes in the middle where we have maximum tensile stresses. In such conditions can we skip "2D" conditions? Please help me.

RE: Hi Everyone, I am designing a be

What is D? Bar diameter? What code are you using?
If they are bottom bars, why are they in maximum tension near the column? That should be a zone of negative moment where the top bars are in tension.

RE: Hi Everyone, I am designing a be

If your beam is short enough that the code prescribed splices end up occurring at or near mid span than the bars should be fabricated to be the full length of the beam with no splices. You may want to stipulate continuous bars in this situation to avoid any ambiguity with the rebar detailer/fabricator.

RE: Hi Everyone, I am designing a be

It sounds like you are trying to detail as a special moment frame where D is the depth of the beam. If it does need to be detailed as a a special moment frame, no you can't skip the requirements. Instead of using a lap splice you may find it advantageous to use a mechanical splice.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
