Bearing Design – Thermal Movement
Estimated Time: 2–3 min | Difficulty: Intermediate

Question
For a longitudinally free bearing 120 m distant from a fixed bearing subjected to ±30°C seasonal variation, the primary concern is:

  1. Longitudinal movement accommodation
  2. Ultimate bending resistance
  3. Fatigue cracking
  4. Seismic isolation
Explanation

Explanation:
Free bearings carry vertical loads but must accommodate thermal expansion and contraction. Thermal movement governs sliding capacity and detailing.
