The effectiveness of welded inclined bars as shear reinforcement in rectangular beam

The use of bent-up bars as shear reinforcement has received little preference from the designers due to the unavailability of space for the anchorage, and also due to the insufficient number of mid-span bars to be bent-up in the shear region near the supports. Welded independent inclined bars (WIB)...

The specimens were tested to failure and their performance was measured in terms of ultimate load, deflection and crack patterns.
