we need the same steel area for the structure
Lap length is the length overlap of bars tied to extend the reinforcement length.. Lap length about 50 times the diameter of the bar is considered safe. Laps of neighboring bar lengths should be staggered and should not be provided at one level/line. At one cross section, a maximum of 50% bars should be lapped.In case, required lap length is not available at junction because of space and other constraints, bars can be joined with couplers or welded (with correct choice of method of welding).
Over lap of steel bar is provided 60 times of dia of steel bar. For example (.5") dia steel bar overlap length is (30"). (.5x60=30")
Lap Length is the length overlap of two rebars tied to extend the reinforcement length. Lap Length of about 50 times the diameter of the bar is considered safe. Let us understand the term “lap length” with an example: suppose there is a need to build a 200ft tall structure, say column. We know that for convenience of transportation, standard length manufactured are upto 12 metre only, hence to strengthen the structure overlapping of two or more bars are done side by side upto the design length. Reason for doing so is the required tension forces that is needed to transferred from one bar to the other. So if diameter of tmt is A then lap length will be 50A. If both diameter is same. Now coming to question, lap length of tmt 550 grade is usually done where minimum bending stress is encountered. We at Shree Ji Steel offer wide range of sizes and grade for various product range which can be checked from our website Shree Ji Steel Corporation.
At what length lapping is to be provided
lap length in tension including anchorage value of hooks in flexural tension shall be greater of development length or 30 times dia of bar. In compression, its equal to development length. In general, 50 times dia is provided.

40 x diameter (12mm) of bars = 480mm

No, it has individual lap bars.
The invention of the lap steel guitar in 1885 is most-commonly attributed to Joseph Kekuku. Lap steel guitars are similar to standard guitars but have some important differences: the strings of a lap steel guitar are raised at the bridge and neck ends, usually one half inch off the fingerboards; the strings of regular guitars have their strings directly against the fingerboards. Because the strings of lap steel guitars are raised and are too high to touch the fingerboard, regular fretted-type playing is impossible; consequently, the number of chords available to lap steel guitars are less than regular fretted guitars. A lap steel guitar player changes pitch by pressing a metal or glass tube against the strings rather than pressing the strings onto a fret. As a result of the fewer chord options and interesting pitch variations, many lap steel players make use of lap steel's rich tones to play melodies. There are three main types of lap steel guitars: Lap slide guitars (e.g., Hawaiian guitar) Resonator guitars--both the round and square neck types (e.g., Dobro, National) Electric lap steel guitars (having up to ten strings) Although lap slide and resonator guitars may be equipped with pick-ups, they do not rely on electrical amplification to be played. The most common use for lap steel guitars is in Hawaiian, country or bluegrass types of music, but they are sometimes used in rock and jazz. Lap steel guitars are commonly played on a lap, but some players use a stool or table.Lap steel guitars are most commonly played with a right-hand thumbpick and up to four left-hand fingerpicks. Some notable lap steel guitar players include Ben Harper, Sneaky Pete Kleinow, Junior Brown, John Fahey, Orville Johnson, David Hildago, Bob Brozman, and Ben Keith. The price ranges of Lap Steel Guitars is quite varied with new models costing as little as one hundred dollars; however, vintage lap steel guitars--especially resonator-type guitars--may be priced in the many thousands of dollars.
You replace them with the correct length bars, and hope never to make the same mistake again.
Key of E
This is the additional length of steel of one structure required to be inserted in other at the junction. For example, main bars of beam in column at beam column junction, column bars in footing etc. The length requirement is similar to the lap length mentioned in previous question or as per the design instructions.

You can get information on a lap steel guitar in a variety of places. The best one is to go to a specialist guitar shop and ask. They are always happy to help provide information.
The lap length for welding a reinforced bar will depend on the size of the bar that is being welded. If the bars are different diameters when lapped, the lap length should be calculated using the lesser diameter.
