PROJECT SUMMARY 
1. RECORDS 
1.1 Test Data 
Data from all tests conducted during Phase 1 of Pro-
ject 334 are filed in Accopress binders. The contents of each 
book are listed in Appendix A.All books will be transferred 
by the writer to Mr. pedro Albrecht, except books X334.91, and 
X334.94 through X334.96 which are with Mr. Karl Frank. 
1.2 Photographic Coverage 
1. 
Appencix B lists the contents of the three photo-
books and six slide-books. This photographic documentation will 
be kept by Dr. John W. Fisher. 
The negative numbers of the photos used in the final 
project report No. 334.2, in the ASCE paper (July 1971), and for 
the dissertation are listed in Appendix C. 
Negatives are filed either in the current file with 
Mr. R. Sopko, or in the dead file, Room 701. 
1.3 Material Inventory 
Four cover-plated test beams and two flange-spliced 
beams remained untested as indicated in Appendix D. A number 
2. 
of beams were also retained for further studies. This includes 
plain-welded beams with a large number of cracks for examination 
of porosity ln the fillet weld, cover-plated beams instrumented 
for crack propagation studies, and eTA-beams tested in reversal 
at the welded end of the cover plate. 
A large number of crack specimens used for fracto-
graphic examination are available. Most crack specimens that 
were photographed are located in the metal cabinet at the wall 
towards the Vibrophore, except PW and uncut specimens. The 
latter are stored on the shelves adjacent to the Machine Shop 
in the old laboratory. 
2 . PROJECT STATUS 
2.1 Experimental Program 
The experimental program for ~roject 334-1 has been 
completed and published in HRB Report No. 102. 
2.2 Reports 
The reports listed in Appendix E reported findings 
. from this project or were supported by this project.
