LAP SPLICING, A or B??
LAP SPLICING, A or B??
(OP)
Good Day!
I'd like to ask on which of the two, A or B, is possible and what Lap Class is this considering the part, "more/less than one half of the bars were spliced at any section"? (more: CLASS B; less: CLASS A)
I am really confused on the, "more/less than one half of the bars were spliced at any section".
Thank you for your responses!

RE: LAP SPLICING, A or B??
Using scheme A would allow you to have shorter lap length since less than 50% of bars are spliced at any section
Scheme B splices 100% of bars at the same section and therefore you are penalised with longer lap lengths.
Not sure of your code, but some I used reward further if you splice less than 33% or even 25%.

Note, I just noticed that I have exactly 50% of the bars spliced which wouldn't qualify for the reduction in lap length, pretend there's a 5 set of bars in that sketch.
