碩士 === 國立中興大學 === 土木工程學系所 === 98 === The objectives of this study are to investigate the design and analysis of the column base plates in the steel buildings. According to the version of ASD(1989), LRFD(1986), LRFD(1993), LRFD(1999) and AISC(2005) which published by American Institute of Steel Construction (AISC) to be the object of this study. All theory of column base plates in these versions would be detailed, include the dimension (N and B) and the thickness (tp) of the column base plate, and by the calculation of the example we could know well about the meaning of the specification. Moreover, we can compare the difference of these versions. On the other hand, when we discuss the effect of column base plate which caused to the moment, we also introduce the design and the theory about resistance of the column base plate to the moment clearly, and we would compare the difference of ASD(1989), LRFD(1993), LRFD(1999) and AISC(2005). By the outcome of this research, we found out the version of AISC(2005) is more economic than the version ASD(1989) when using the way of Allowable Strength Design(ASD), and we could get the same size and thickness when using the way of Load and Resistance Factor Design(LRFD). And we could get more economic size of design of the column base plate by the way of Load and Resistance Factor Design (i.e., LRFD(1986),LRFD(1993), LRFD(1999) and the LRFD parts of AISC(2005)) than the way of Allowable Strength Design(ASD).
