Suradjin Sutjipto received his Sarjana degree in Civil Engineering from
Trisakti University in 1985. He completed work for his master's degree in
Earthquake Engineering under the guidance of Professor Gary C. Hard and
Professor Robert E. Englekirk at the University of California, Los Angeles
(UCLA) in 1990.
According to his professors, as a straight-A UCLA graduate, Suradjin was
inquisitive and sought an in-depth understanding of not only technical
material, but design procedures and philosophy. He possesses an excellent
technical understanding of both reinforced concrete and structural steel.
Professor Kenneth B. Bondy, who was also a member of the ACI Committee 318,
stated that Suradjin is possibly the best graduate student to study under him at
Suradjin Sutjipto has been developing his career by combining both practical
and academic professions. As a Practicing Engineer, he has designed several
prestigious projects not only in Indonesia, but also in California (USA) and
Taiwan. He is a licenced Professional Structural Engineer. As a Lecturer, he
currently teaches some design classes in the Civil Engineering Department of
Trisakti University and Tarumanegara University.
Suradjins' practical experience improved significantly when he joined in
Robert Englekirk Consulting Structural Engineers, Inc. (REI), one ot he largest
and most respective structural engineering firms in the United States, in 1989.
He developed the design of a 60-story steel building in Taiwan. Environmental
conditions required that the building withstand strong earthquakes and typhoons.
The resulting bracing system incorporated eccentrically braced frames,
stabilizing trusses and composite columns.
Due to Suradjin's ability to accomplish the design work fast and accurately,
the REI engineers called him "boy wonder". He finished the
structural design pricing packages of a 40-story reinforced concrete building
within 4 days and a 45-story steel building within 5 days, assisted by only 2
engineers and 4 draftsmen. That 40-story reinforced concrete buildings was
supposed to be the tallest concrete building in Southern California.
Nevertheless, Suradjin's practical experience is not limited to high-rise
building systems. He has designed post-tensioned floor slabs, mat foundations,
shoring systems for deep basements and the components of many low-rise
Under Suradjin's coordination, the structural design of Gedung Sapta
a 25-story reinforced concrete building in Jakarta, was done economically
without sacrificing the architectural needs. The lateral resisting system of the
building was designed by combining some ductile cantilever shear walls, coupled
shear walls and moment resisting frames stabilized by an RC cap-beam system.
Along his career, Suradjin has authored several technical papers and research
reports which have been presented in some seminars. He has also developed
numerous structural computer programs for both commercial and in-house uses. At
the request of Professor Mario Paz, Suradjin completed a chapter for Indonesia
in Pfrofessor Mario Paz's book entitled International Handbook of Earthquake
Engineering including a related interactive computer program called
INSEC. One of Suradjin's paper, Ductile Eccentrically Braced Frames-Behavior State
Analysis, received the
Structural Response to Ground Motion Award in 1989.
