  40. Conclusion

  41. Conclusion • Fix support condition generally conduct most conservative results for anchor forces. • Design procedure for anchor tolerance situation. • Model baseplate for Case 1 and Case 2. • Find out maximum plate stress based on Case 1. • Find out the most critical anchor by Case 1 and Case 2 analysis. • Use Engineering Judgmentto determine the worst case for anchor force. • Temperature change during operating is negligible to baseplate and anchorage design.
