偏心軸荷重을 받는 拘束PC長柱의 極限强度와 擧動解析 = Behavior and Ultimate Strength of Eccentrically Loaded Restrained Prestressed Concrete Slender Columns

다국어 초록 (Multilingual Abstract)

One of the most important elements of any structural frame is the column. This element is usually under the action of combined axial load and bending moment. Columns with small slenderness ratios are usually analysed by simple consideration of the equilibrium of forces and compatibility of strains. On the other hand, for columns with large slenderness ratios, the compound effect of the axial load and column deflection adds to the column bending moment, thus reducing of the column ultimate capacity.
In this study, the analytical method for the Behavior and ultimate strength of Eccentrically Loaded Restrained PC slender Columns is developed, including the material and geometrical nonlinearities and the nonlinear behavior of restrained end of a column in a frame.
Accordingly, the objectives of this investigation are to use the method developed to conduct a parametric study of the different variable (Rotational Restraints, Ratio of End Restraints, End Eccentricity, Ratio of End Eccentricities, Lateral Restraints, Concrete Strength) influencing the behavior and the ultimate strength for PC columns.
