Journal ArticleDOI
TL;DR: In this paper, the authors considered uniformly loaded circular diaphragms, which are assumed to be isotropic, and presented the results of a study on the influence of bending stress and tensile stress, which together determine the diaphrasm deflection.

TL;DR: In this article, the behavior of prestressed, composite steel-concrete beams under positive bending moment is examined, and the benefits of different types of prestressing are compared, and three specimens were tested to study various aspects of the prestressed composite girders, including tendon type and profile.
Abstract: According to the 1986 U.S. Federal Highway Administration statistics, there are 575,607 bridges on the highway systems. About half of these bridges are structurally deficient and/or functionally obsolete. To strengthen the structurally deficient bridges without replacing the girders, external prestressing techniques can be used. In this paper, the behavior of prestressed, composite steel-concrete beams under positive bending moment is examined, and the benefits of different types of prestressing are compared. Three specimens were tested to study various aspects of prestressed composite girders, including tendon type and profile. Two methods of analysis are discussed, i.e., the transformed area method and the strain compatibility method. The test results show that prestressing a composite girder increases the range of elastic behavior, reduces deflections, increases ultimate strength, and adds to the redundancy by providing multiple stress paths. Based on the experimental results, a comparison was made between three tendon types and profiles. It was concluded that strands are more effective than bars for the tendon type, and a straight tendon profile is more effective than a draped profile with regard to stiffness.

Journal ArticleDOI
TL;DR: In this article, the authors investigated the dynamic response and stability of two identical free-standing slender columns capped with a freely supported rigid beam and found that the dynamics response of the rocking frame is identical to the rocking response of a solitary, free standing column with the same slenderness, yet with larger size.
Abstract: This technical note investigates the dynamic response and stability of a rocking frame that consists of two identical free-standing slender columns capped with a freely supported rigid beam. Part of the motivation for this study is the emerging seismic design concept of allowing framing systems to uplift and rock along their plane in order to limit bending moments and shear forces— together with the need to stress that the rocking frame is more stable the more heavy is its cap-beam, a finding that may have significant implications in the prefabricated bridge technology. In this technical note, a direct approach is followed after taking dynamic force and moment equilibrium of the components of the rocking frame, and the remarkable results obtained in the past with a variational formulation (by the same authors) is confirmed—that the dynamics response of the rocking frame is identical to the rocking response of a solitary, free-standing column with the same slenderness, yet with larger size, which p...
