Shear at Interfaces

This lecture covers the topic of shear at interfaces in concrete structures, discussing longitudinal shear, shear between panels, and shear forces between concrete elements cast at different times. The presentation also addresses the implementation of shear forces in joints and the influence of reinforcement crossing the interface. Various design considerations and factors affecting shear resistance are explained, including surface characteristics, joint shear strength, and the transmission of shear forces. Practical examples and recommendations for interface shear transfer are provided, along with details on the implementation in design codes. The lecture emphasizes the importance of proper detailing and reinforcement to ensure structural safety and integrity.
