Global Lateral Buckling of I-Shaped Girder Systems

Author: Yura Joseph, Helwig Todd, Herman Reagan, Zhou Chong | Size: 0.5 MB | Format: PDF | Quality: Original preprint |
Publisher: Journal of Structural Engineering; Vol. 134; Issue 9 | Year: Sep2008 | pages: p1487-1494, 8p.

Abstract:
A closed form solution for elastic global buckling of twin girder systems interconnected with cross frames is derived. Current design specifications for such systems only consider individual girder buckling between cross frames. The solution, which is suitable for design specifications, was developed for a uniform moment loading condition. Finite-element analyses (FEAs) were used to verify the closed form solution and extend it to more practical loading conditions. FEA showed that the load height condition had only a minor effect for twin girders compared to the published effects on single girders. Both singly and doubly symmetric sections were studied and showed that the girder spacing and the in-plane moment of inertia of the girders are the principal variables controlling global buckling of twin girders. The number and size of the intermediate cross frames had little effect. A method for improving the global buckling capacity through the use of a partial top flange lateral bracing system is presented along with a design example

Shear Resistance of Transversely Stiffened Steel I-Girders

Author: White Donald W., Barker Michael G. | Size: 0.3 MB | Format: PDF | Quality: Original preprint |
Publisher: Journal of Structural Engineering; Vol. 134; Issue 9 | Year: Sep2008 | pages: p1425-1436, 12p.

Abstract:
This paper evaluates the accuracy and ease of use of 12 of the most promising models for the shear resistance of transversely stiffened steel I-girders. Several models that are well established in civil engineering practice as well as a number of other recently proposed models are considered. As the model developed in Basler’s seminal research is the method of choice in current American practice, the paper focuses on the merits and limitations of the alternative models relative to Basler’s. Statistical analyses are conducted on the predictions by the various models using an updated data set from 129 experimental shear tests, including 30 hybrid and 11 horizontally curved I-girders. The results support the conclusion that the form of Basler’s model implemented in 2004 AASHTO LRFD Bridge Design Specifications and 2005 AISC Specification for Structural Steel Buildings gives the best combination of accuracy and simplicity for calculation of the shear resistance of transversely stiffened steel I-girders.

Alternative Approach to Optimal Tuning Parameter of Liquid Column Damper for Seismic Applications

Author: Aparna Ghosh and Biswajit Basu | Size: 0.084 MB | Format: PDF | Quality: Original preprint | Publisher: Journal of Structural Engineering, Vol. 133 Issue 12 | Year: Dec2007 | pages: p1848-1852, 5p | ISBN: 0733-9445

A closed-form solution for the optimum tuning ratio of a liquid column damper (LCD) that is valid for damped structures subjected to generalized seismic loading is presented. The closed-form expression is based on the extension of the theory of “fixed-point” frequencies for a classical undamped structure-mass damper system to damped structure-nonlinear LCD system. For the specific case of white noise input, the values of optimum tuning ratio have been compared with those obtained from a standard expression.

Seismic Vibration Control of Nonlinear Structures Using the Liquid Column Damper

Author: Aparna Ghosh and Biswajit Basu | Size: 0.67 MB | Format: PDF | Quality: Original preprint | Publisher: Journal of Structural Engineering, Vol. 134 Issue 1 | Year: Jan2008 | pages: p146-153, 8p | ISBN: 0733-9445

A design methodology for a variation of the conventional liquid column damper (LCD) (by attaching a spring connection to the LCD) as a seismic vibration control device for structures with nonlinear behavior has been proposed in this paper. The proposed method with the nonconventional damper has the advantage of being applicable to nonlinear structures having high initial stiffness (short natural period) in the linear range below yield with subsequent period lengthening in the postyield phase, where the conventional LCD would be ineffective. The reason for the lack of effectiveness is not only due to the damper parameters designed for the linear structure becoming inapplicable when the structures move to the inelastic regime but also because of the restriction imposed by the high natural period of the conventional damper on its applicability to comparatively stiff structures (for tuning). The methodology in this paper, thereby incorporating the use of a modified model of the LCD system, namely a spring-connected one, removes the requirement on the natural period of the liquid in the LCD and further, the design is based on the parameters of an equivalent linear system for the nonlinear structure.
