碩士 === 國立中興大學 === 土木工程學系所 === 99 === When eccentricity occurs in the plane of the faying surface, the bolt must be designed to resist the combined effect of the direct share and the additional shear from the induced moment. Two analysis methods for bolted connections of eccentrically loaded are the elastic method and the ultimate strength method. The ultimate analysis, which specified in AISC design manuals, has been used for the analysis of eccentrically loaded connections which is bolted. In the current AISC design manual, tabulated solutions for eccentric loads inclined at specified angles from vertical are provided. For the cases which inclined angles are in the range of 75°≦θ≦360°, the current AISC manual does not furnish available tables to apply. This study to evaluate the strength of eccentrically loaded connections, which are not limited to the bolt patterns listed in current AISC manuals, are presented and compared. A numerical procedure for the analysis of eccentric loads that are inclined at any angles from vertical is furnished. This will also accomplish a better solution for practicing engineer in their routine design.
