Design Philosophy • Limit States –Strength –Serviceability –Fatigue and Fracture –Extreme Event • Ductility •Redundancy • Structural Integrity
Grout Pockets • Technique – precast voids/pockets in cap to contain column connectors • Advantages – flexibility in size and shape – large construction tolerances – simple grouting operation • Disadvantages – cracking potential at large top surface – congestion of reinforcement – larger volume of grout
