41. Baseplate Analysis for Anchor Bolts Tolerance Using GT STRUDL Base Plate Wizard Copyright © 2012 URS CONFIDENTIAL – This document is proprietary and competitively sensitive. Any disclosure, copying, or use of it is strictly prohibited. Conclusion Fix support condition generally conduct most conservative results for anchor forces. Design procedure for anchor tolerance situation. a) Model baseplate for Case 1 and Case 2. b) Find out maximum plate stress based on Case 1. c) Find out the most critical anchor by Case 1 and Case 2 analysis. d) Use Engineering Judgment to determine the worst case for anchor force. Temperature change during operating is negligible to baseplate and anchorage design. 41
