will be added. This section will provide the calculation summary that describes the analysis of the bridge runway rail and rail clips following addition of the modified rail clips. This modification will be completed prior to use of the crane as a single failure proof crane. Drawings associated with the rail clip design and the placement of the rail clips on the runway girder are included as part of this attachment.

- h. Calculation ZIONOO1-CALC-034, Fuel Handling Building (FHB) 125 Ton Crane Rail Clip Modification and Rail Evaluation Summary: Calculations performed in calculation ZION001-002, Appendix B, demonstrated that the original runway rail and rail clip design is not adequate for the new design basis load case for a seismic event with a load on the hook. This new calculation evaluates the proposed rail clip modification and the runway rail with the proposed modification installed.
Model/Methodology
Description:
Simplified hand calculations are used to design a new crane rail clip assembly using MathCad 15. Governing crane wheel forces at the top of the crane rail for all crane and trolley positions for each of the load combinations from Attachment 56 of Ref. 3.7 are considered in the calculation for the new rail clip design.
As-built survey data of the crane runway rail determined the maximum existing clip center to center spacing to be 2ft.-7in. The majority of the existing clips are 2 ft.-O in.
center to center spacing. The new rail clips will be installed between two existing rail clips providing generally the same center to center spacing (2 ft. -0 in.) as the existing design. Conservatively, the new clips are designed for full wheel forces applied to a single rail clip without relying on the distribution of forces to the adjacent existing clips providing unanalyzed margin.
When a horizontal seismic load from the crane wheel is applied to the head of the crane rail, the force is decoupled into a bearing force on one edge of the crane rail base (bottom flange) along with the corresponding shear force and an uplift force on the opposite edge of the crane rail base (bottom flange). There are rail clips on each edge of the base (bottom flange) of the crane rail. Therefore each clip will either see force from shear with corresponding bearing or force from uplift. No credit is taken for friction between the bottom flange of the rail and the girder. On the bearing side, clips and bolts are designed for the applied shear force. On the uplift side rail clips and bolts are designed for the bending moment due to the rail bearing on the rail clip support.
The crane rail is checked for the applied forces for web shear, web bending and local rail base (bottom flange) bending.
Reference 1: Attachment 1 The rail clip is connected to the top flange of the bridge runway girder. A local stress check of the crane runway girder flange for the applied rail clip forces is also performed.
Crane girder global analysis for the applied new rail clip forces is not within the scope of this calculation. Calculation ZIONOO1-CALC-002 (Ref. 3.7) describes the crane runway girder analysis.
Assumptions: Assume existing 175 lb crane rail is 50ksi material. Per documentation attached to the calculation, minimum yield stress for rail head, rail web and rail base (bottom flange) for controlled cooled crane rail range from 65ksi to 90 ksi. Therefore, this is a conservative assumption and does not need to be verified.
Results: The highest loads and stress values along with allowable values are listed below. Note there are two clip styles; Clip 1 is the standard clip, Clip 2 is located at column tie-backs. The values below are for the limiting clip style for each load type.
