Analysis Guidelines • Structural Analysis – simplified approach: actions based on worst case of pinned vs. fixed connection at top of column/pile – general approach: estimate connection stiffness – load factor actions at connection increased by 30% • Strength – P-M analysis of connector cross-section – shear friction, V n = cA g + µ [A v f y + P c ] – joint shear, V n = 12 b j h

Analysis Guidelines<br />
• Structural Analysis<br />
– simplified approach: actions based on worst case of<br />
pinned vs. fixed connection at top of column/pile<br />
– general approach: estimate connection stiffness<br />
– load factor actions at connection increased by 30%<br />
• Strength<br />
– P-M analysis of connector cross-section<br />
– shear friction, V n = cA g + µ [A v f y + P c ]<br />
– joint shear, V n = 12 b j h
