# Tendons in a Continuous Beam In a continuous beam, the tendons (prestressing tendons) are arranged to optimize the structural performance and efficiency. ## Typical Tendon Profile - Tendons are **normally high over supports** to resist the negative moments. - Tendons are **low at midspan** where positive moments are predominant. ## Explanation 1. **Over Supports:** - Negative moments occur over supports in continuous beams. - To resist these moments, tendons are **located closer to the top fiber** (high over supports). 2. **At Midspan:** - Positive moments are greater at midspan. - Tendons are **located closer to the bottom fiber** (low at midspan) to counteract these moments. 3. **Result:** - This profile, often called a **parabolic or variable profile**, helps in efficient prestressing. - It reduces bending moments and optimizes material usage. ## Final answer: **High over supports and low at midspan** --- **Summary:** | Profile Type | Description | |--------------|--------------| | **High over supports, low at midspan** | Correct, as tendons are arranged to counteract the negative moments at supports and positive moments at midspan. | **Therefore, in a continuous beam, tendons are normally:** **High over supports and low at midspan**
