Park Synopsis: An outline is given of the many significant and pioneering contributions made by Emeritus Professor Tom Paulay to the understanding of the behaviour of reinforced concrete a
24、nd to the design of reinforced concrete structures for earthquake resistance. Particularly innovative has been his research into the design of structural walls for earthquake resistance, including the concept of the use of diagonal reinforcement in coupling beams. Other internationally recognised re
25、search described are his outstanding investigations into the mechanisms of shear resistance of reinforced concrete, aggregate interlock across cracks, behaviour of beam- column joints, and the capacity design and detailing procedures for structural walls and frames. 1 AC1 SP-157 95 Obb2949 0524389 T
26、71 2 Park R. Park, FACI, is Depuiy Vice-Chancellor and a Professor of Civil Engineering at the University of Canterbury, Christchurch, New Zealand. He has teaching and research interests in reinforced and prestressed concrete structures, particularly in the design for earthquake resistance. He is th
27、e author or co-author of more than 200 technical papers and two books. He has received 16 awards from North America, United Kingdom and New Zealand for his published papers. FROM CAVALRY OFFICER TO UNIVERSITY PROFESSOR Born in Sopron, Hungary on 26 May 1923, Tom Paulay was initially destined or a li
28、fe in the Royal Hungarian Army. After attending a boarding school for military cadets in Sopron he entered the Royal Hungarian Military Academy in Budapest. On graduating he was posted as a second lieutenant to the same cavalry regiment in which his father served for many years. One year later, in 1
29、944, he faced the advancing Russian army in the Prypet Marches of the then Eastern Poland. At the age of 21, after mounting casualties, he found himself in command of a cavalry squadron consisting of 278 men and 308 horses. Action in Poland and later in Hungary, and months spent in various military
30、hospitals, left him somewhat deaf, a feature remembered by his later colleagues and students. After discharge from the army in 1946, with many other returned servicemen he joined the first year civil engineering class of 360 at the Technical University of Budapest. Describing this stage of his life,
31、 Tom Paulay has written that: The Technical University of Budapest afer 52 days siege of the city was barely habitable. The fact that during the winter snow fell through large holes in the ceiling of the largest lecture room, did not interfere with the attraction with which brilliant lectures in eng
32、ineering mathematics were followed. The professor wore two raincoats (his winter coat was buried under his house) and he wrote his equations on the blackboard wearing knitted gloves. Dozens of shallow graves all over the campus, where German, Russian and Hungarian soldiers had been hastily buried du
33、ring the battle of Budapest, were daily reminders. They stifled any temptation to grumble about physical deprivations. Reliance by students on fellowship was a prerequisite to preserve sanity in the process of coping with hunger, the cold and the immense academic pressure. AC1 SP-157 95 Obb2949 0524
34、390 793 Lateral Force Transfer in Buildings 3 The compromise between preserving free entry to the university and the greatly diminished immediate need for engineers in a totally collapsed economic system, resulted open in 75% failure rates at the end of the first year. While physical conditions impr
35、oved slowly the political scene deteriorated dramatically. By 1948 Joseph Stalin and the Red Army imposed virfually full control over society by means of channelling the power into the hands of the Communist Party and its tool, the political police. For them to subdue within the campus an idealistic
36、 and hopeful but largely apolitical student body, was a formidable task However, the outcome was inevitable. In 1948 Tom Paulay was one of the few who escaped from the Budapest equivalent of Rochester Hall (a Catholic hall of residence at the University of Canterbury), dissolved overnight by governm
37、ent orders. He made it across closely guarded forests to Austria and West Germany. Most of his fiends, including his roommate, did not succeed. They spent some five years in a concentration camp: In West Germany he enrolled at the Technical University of Munich but lack of financial resources soon t
38、erminated his attempt to continue civil engineering studies. For three years he occupied himself with international student relief activities, sustained by charitable organisations, in his new status as a stateless person. At this stage he began to teach himself English. His next turn of fate favour
39、ed New Zealand. He was offered a scholarship by a small group of Catholic students from Victoria University of Wellington, New Zealand. As a result, in 1951 the International Refuge Organisation delivered Tom Paulay, his wife Herta and baby daughter to New Zealand. Two years later he completed a Bac
40、helor of Engineering (Civil) degree at Canterbury University College. Before graduating he had brief periods of work experience as a maintenance labourer with New Zealand railways and as a labourer in woolstores. After completing BE (Civil) he worked for eight years as a structural engineer with a f
41、irm of consulting engineers in Wellington, where his ability and instinct for structural design became clearly evident. In 1961 he joined the Department of Civil Engineering of the University of Canterbury as a Lecturer. There his main teaching interest was the application of engineering fundamental
42、s to creative structural design. He proved to be a gifted and popular teacher. Encounters with students in the classroom were a prime source of joy to him. The students responded with enthusiasm, in spite of the high demands placed on them, and profited greatly from the experience - a very fortunate
43、 generation of students indeed. At the urging of the then head of department he embarked on research work in 1964 which led to a PhD degree in 1969. Progressing through the steps in the academic ladder, in 1975 he was appointed to a person chair (professorship) in civil engineering at the University
44、 of Canterbury. AC1 SP-157 95 Obb29i.19 0524393 b2T a 4 Park He has maintained a continued interest and intense involvement in research at the University of Canterbury during the last thirty years. Although his first technical paper was published in 1967 when he was age 44, he has published 100 publ
45、ications since that date, comprising 3 books, 9 book chapters and parts of seminar volumes, 58 papers in refereed journals and 30 papers in conference proceedings (see the attached list of publications by T Paulay). His publications have had a major impact on the seismic design of concrete structure
46、s and have been recognised by numerous awards and prestigious appointments both in New Zealand and overseas. In 1983 he was elected to Fellowship of the Royal Society of New Zealand and in 1987 to Honorary Membership of the American Concrete Institute, the 23rd non-American so honoured since 1926. H
47、is services to civil engineering were marked by the Professional Commitment Award of the Institution of Professional Engineers New Zealand in 1985, and by being made an Officer of the Order of the British Empire in 1986. He has also received honorary doctorates from the Swiss Federal Institute of Te
48、chnology and the Technical University of Budapest. He retired from the University of Canterbury in 1989 after 28 years of extraordinary service and achievement. Although retired he has maintained strong ties with his colleagues, attending most days to work in his study and to talk with staff, studen
49、ts and visitors at the University of Canterbury. He has also kept a high international profile, becoming the President of the International Association for Earthquake Engineering in 1992. RESEARCH Tom Paulays research during the last thirty years has had a profound effect on current understanding of aspects of the behaviour and seismic design of reinforced concrete structures. His many publications are highly regarded internationally for their deep and significant contributions. Indeed many of his publications have become classics. This research work has built on his uncanny ability
