| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 82 === The fireproof capacity of coated steel structure is maintain by
fire resistance rating(t), and the rating is close to section
scale factor (W/D, unit weight/section fired circumambience) of
steel structure and coating material thickness(T). The study is
according to the view of section scale factor transfer, put all
kinds of H style to be 45cm2 but differ thickness steel plate,
make to small scale specimen, therefore, applying standard
curve time-temperature under CNS 12514 to proceed truly fire
resisting test of single degree heated model for small scale
specimen ,and realize the truly relationship of t, T and W/D.
However, according to theory analysis the feasibility of using
small-scaled specimen replace coating steel structure and
proceed the appraise of fireproof capacity. The kinds of
coating steel structures are so much, so only study the model
of wet coated structure (horizon-heating) painted around H
style section.@ The study result detect that the mutidegree
coating steel beam structure will transfer single degree small
scale specimen and proceed fire resisting test by section scale
factor, but must consider water evaporate condition and the
affect of small specimen lost heat in high temperature. During
the relationship of t, T and W/D, t is proportional with T and
W/D. Form the result, the paper point of sprayed thickness of
beam transfer formula common using now, and the managing method
for examining the external qualify materials that recognized by
the domestic authorities concerned, to provide the actual
suggestion for the accordance of improving and examining.
