Video Summary
Good evening. Tonight we discussed the concept of harping and applying it to the strand pattern of a pre-stressed concrete beam. We looked at the implications of changing the strand pattern on the stress distribution and how it can help address compression and tension stresses. We explored the process of adding top steel as a solution for tension stresses and discussed the design considerations for this reinforcement. Finally, we recalculated the losses and checked the service load conditions to ensure the design meets the necessary requirements. Overall, changing the strand pattern and adding top steel proved to be effective in controlling the stress distribution and ensuring the beam's structural integrity. We will continue with session five next week. Thank you and have a good night.
