Creep in Continuous Beam Built Span‐by‐Span
Journal of Structural Engineering, 1983The long-term variation of bending moment distribution caused by creep in a continuous beam errected sequentially in span-length sections with overhangs is analyzed. A linear aging creep law is assumed. The problem involves changes of the structural system from statically determinate to indeterminate, a gradual increase in the number of redundant ...

Journal of Structural Engineering, 1983
The multiple Fourier technique is used to compare the stress fields in single span deep beams due to uniform loading at the top edge and at the bottom edge. The method involves the superposition of three stress functions. The first stress function is used to satisfy the boundary conditions on the upper and lower edges of the beam.

CFRP Repair of RC Beams with Shear-Span and Full-Span Corrosions
Journal of Composites for Construction, 2010This paper presents experimental and analytical results of a study conducted to investigate the use of carbon fiber-reinforced polymer (CFRP) laminates to rehabilitate shear-span and full-span corrosion-damaged RC beams. Fifteen RC beams were fabricated and were divided into three groups: control, shear-span, and full-span corrosions.

Journal of Sound and Vibration, 2008
Abstract This paper treats the orthogonality condition for a multi-span beam, and its application to forced (transient) vibration of a two-span beam. The beam is modeled as a Bernoulli–Euler beam. The boundary conditions for the particular case of two-span beam are clamped–pinned–pinned.

MEASUREMENT OF DEFORMATIONS OF BEAM SPANS OF BRIDGES
World of Transport and Transportation, 2016The necessity of application of mobile measuring and computing systems for diagnosing bridges is shown, as well as an analysis of the results of measurements of flexural deformations and natural vibration frequencies of a beam reinforced concrete spanning structure of a railway bridge during the movement of a train is provided.

Localization of Vibration in Disordered Multi-Span Beams With Damping
14th Biennial Conference on Mechanical Vibration and Noise: Structural Dynamics of Large Scale and Complex Systems, 1993Abstract The combined effects of disorder and structural damping on the dynamics of a multi-span beam with slight randomness in the spacing between supports are investigated. A wave transfer matrix approach is chosen to calculate the free and forced harmonic responses of this nearly periodic structure.
