| Summary: | 碩士 === 國立中興大學 === 土木工程研究所 === 83 === This research mainly focuses on the effect of
unsymmetrical loads acting on the steel scaffolds and
the effect of initial sidesway of steel scaffolds for high-
clearance reinforced concrete structures. The research work
includes two parts, namely experimental and theoretical
parts. Studies three-story steel scaffolds were adopted in
experimental in which the effects of unsymmetrically applied
loads and the initial sidesway of the steel scaffold
system were investigated in these tests. The commercial code
NASTRAN providing both eigenvalue and second-order
elastic analyses are used in the theoretical approach. It
was found that the load-carrying capacity of tubes of the
scaffold will control the failure of the entire system, even
if the system has unsymmetrically applied loads and initial
sidesway on steel scaffolds. The use of the traditional
jack base and the stiffened jack base can increase the
loading capacity of system up to 17% - 33% and about 59%
respectively in comparison with that of steel scaffold
system without jack bases.
