Steel bars are generally connected together to get greater length than the standard length by providing A. Straight bar splice B. Hooked splice C. Dowel splice D. All the above

The correct answer is: All of the above.

Steel bars are generally connected together to get greater length than the standard length by providing:

• Straight bar splice: This is the simplest type of splice, where the ends of the bars are simply welded together.
• Hooked splice: This type of splice is stronger than a straight bar splice, as the ends of the bars are bent into hooks that interlock with each other.
• Dowel splice: This type of splice is the strongest, as the bars are connected with dowels that pass through holes in the bars.

The type of splice used will depend on the load-bearing requirements of the structure.
