Student Paper Presented At SNAME Northern California

The annual student paper meeting of the Northern California Section of The Society of Naval Architects and Marine Engineers was held recently at the Engineers Club in San Francisco. This meeting was also Past Chairmen's Night, with many past section chairman attending as honored guests.

The technical portion consisted of a paper by Ygal Shapir and Gregory J. White, University of California, Berkeley, titled: "An Analysis of the Ultimate Strength of Deck Structures Under Inplane Loads." In the paper, a step-bystep procedure for determining the mode of failure and the ultimate strength of ship deck structures under compressive loads was developed. A comparison of several analytical t h e o r i e s for buckling strength in the elastic and inelastic zones was presented, and the reason for the approach taken at each step in the procedure explained.

The final results are a flow chart and an algorithm, which is easily adapted to most computer systems. A program written in FORTRAN was included in the paper, together with input and output examples. A discussion period followed presentation of the paper by co-author White.
