# Tendons in a Continuous Beam ## Question In a continuous beam, tendons are normally- Low over supports and high atspan - High over supports and at midspan - Randomly ## Explanation In post-tensioned or prestressed concrete beams, tendons are typically arranged to counteract the bending moments experienced by the. ### Bending moments in a beam: - **Negative moments** occur over supports. - **Positive moments** occur at midspan. ### Tendon profile: - Tendons are **preferably anchored** where the **tension** is required most. - To **counteract negative moments** over supports, tendons are **more anchored or positioned near the bottom** at supports to resist upward bending. - To **counteract positive moments** at midspan, tendons are **more anchored or positioned near the top** at midspan. ### Typical Tendon Profile: - Tendons are **depressed in the midspan** (lower at midspan) and **raised over supports** (higher over supports). **Therefore:** - Tendons are **low at midspan** and **high over supports**. ## Final answer: **High over support and low at midspan.** ```markdown # Correct choice: - **High over support and low at midspan** ```
