AFFIDAVIT OF DR. METE A. SOZEN My name is METE A. SOZEN.
I am a Professor of Civil Engineering at the University of Illinois, at Urbana-Champaign.
My testimony in this proceeding is offered in my capacity as a private consultant to Bechtel Power Corporation l
and not on behalf of the University of Illinois.
I am the author of the enclosed report entitled
" Evaluation of the Effect on Structural Strength of Cracks in the Walls of the Diesel Generator Building, Midland Plant Units 1 and 2, Midland, Michigan", except for Attachment 4 thereto which was written by Dr. W. Gene Corley.
This report was originally submitted to the NRC Staff in February, 1982.
I received my BS in Civil Engineering from Robert College in Istanbul and continued my education at the University bU21U80350 82b9OB l'
f PDR ADDCK 05000329 T
l
, of Illinois in Urbana to receive my MS degree in Civil Engineering in June, 1952.
After work in two structural design firms, I returned to the University of Illinois in September 1953 for further graduate work, specializing in structural mechanics and behavior of reinforced and pre-stressed concrete structures subjected to static and dynamic loads.
Having completed my doctoral dissertation in 1957, I continued on the faculty of the University of Illinois, with my time devoted primarily to research and graduate educa-tion in structural engineering.
I am a registered Structural Engineer in the State of Illinois.
My research experience is related primarily to pre-stressed and reinforced concrete structures.
Some of the specific topics I have investigated are shear anf flextural strength of prestressed concrete beams, bond, anchorage-zone stresses, crack development and analysis, flexural strength and deflections of reinforced concrete slabs and strength and behavior of prestressed concrete nuclear reactor vessels.
I have inspected and analyzed structural damage resulting from earthquakes in Skopje (1963), Alaska (1964), Caracas (1967),
San Fernando (1971), Managua (1972), Guatemala (1974), and Sendai (1978).
My research in relation to earthquake response of reinforced concrete sturctures is directed at developraent of analytical models for studying the effects of nonlinearities resulting from cracking and yielding.
. In 1977 I was elected to the National Academy of Engineering in recognition of my research on dynamic response of reinforced concrete structures.
Because I teach in a professional school, I have maintained a strong interest in practical problems.
I have contributed to the development of design specifications for flexural and shear strength of prestressed concrete beams and reinforced concrete floor slabs (American Concrete Institute) and earthquake resistance of reinforced concrete structures (Veterans Administration and Applied Technology Council).
Currently I serve as a member of American Concrete Institute Committee 318 (Building Code) and of the Veterans Administration Advisory Committee on Structural Safety.
A more complete statement of my professional qualifications is attached.
My work as a structural consultant has provided me with experience in design and performance of reinforced and prestressed concrete sturctures.
I work primarily to solve problems related to design criteria for new unusual con-struction or evaluation of the effects on building performance of any condition (such as local yielding or cracking) not con-sidered in original design.
I have visited the Midland site and I have reviewed the relevant crack maps and structural drawings and I believe I have sufficient information to evaluate the structural signifi-cance of the cracks observed.
. I swear that the statements in this Affidavit and in the portions of the enclosed report for which I am responsi-ble are true and correct, to the best of my knowledge and belief.
