You are required to design the piles for a timber bridge to resist vertical imposed and permanent actions. The piles are 13.5 m long and are effectively pinned at each end (assume g13= 1.0 for both buckling directions). Cross-bracing is provided in the plane perpendicular to traffic flow, at a maximum spacing of 4.5 m. The material is F14 unseasoned hardwood, which is locally available near the bridge site at Huonville (southern Tasmania). Assuming the piles are circular, determine the minimum nominal diameter required to resist the following loads per pile: • Permanent action 60 kN (compression) • Imposed action (DOL-5 months) 150 kN (compression)
