In 1994 London Docklands Development Corporation held a design competition for a pedestrian bridge to link the new Canary Wharf commercial towers development with the refurbished Victorian warehouses of West India Quay. The bridge is a steel structure with 750x300 U - shaped spine beam. Tapered angles, set diagonally to...
A new type of composite bridge deck, which is under research, is aimed at achieving composite action through the adhesion between a thin cement-based layer and a steel plate without using traditional shear connectors. This paper presents experimental and numerical work carried out on composite beams exposed to negative bending....
In this paper, perforation response of a thin beam struck by a rigid, blunt projectile moving at a high velocity is simulated using, respectively, uniform fracture strain, Johnson-Cook's, and Bao-Wierzbicki's fracture locus for 2024-T351 aluminum alloy. The former two predict that materials in the impacted area of the beam beneath...
Glued laminated timber glulam beams are highly engineered components manufactured from specially selected and positioned lumber laminations of varying strength and stiffness properties. These fabricated beams are often specified where a certain span, strength and/or stiffness is required. As such, glulam beams are generally designed for and used in applications...
Although steel single angle sections are commonly used as beams to support distributed loads, which cause biaxial bending and torsion, their behavior may be extremely complicated, and the accurate prediction of their strengths very difficult. In this paper, an approximate method of predicting the second-order deflections and twist rotations of...
This paper is concerned with large twist rotations of elastic thin-walled open section beams, which induce additional longitudinal stresses, which exert non-linear "Wagner" stiffening torques. The non-linear behavior of a narrow rectangular beam is first analyzed and then this is extended to elastic beams of general cross-section. Expressions are derived...
This paper reports on a research project aimed at investigating the response mechanism of a composite moment-resisting frame system with self-centering and energy dissipation capabilities. The suggested configuration of a particular composite beam and column members in a portal frame structure, serving as a simplified example of a moment-resisting frame...
Glued laminated beams glulams are used in a wide range of applications in both commercial and residential construction. The tables in this paper provide recommended preliminary design loads for two of the most common glulam beam applications: roofs and floors. The recommendations in this paper apply to glulam beams bearing...
The loads applied to angle beams usually act out of the principal planes so that they cause simultaneous biaxial bending about both principal axes. This paper investigates the biaxial bending of unbraced steel angle beams. The biaxial bending of compact equal angles in uniform bending is considered first, and a...
For heavy loads and long spans, engineered beams are the way to go. This article compares LVL, glulam, and Parallam, plus some new composite beams. Engineered lumber is uniform, reliable, and available in continuous lengths (up to 80 feet in some cases) and is manufactured to a low, 7% to...
Current methods of flexural strengthening of reinforced concrete beams with fiber-reinforced polymer FRP strips require time-consuming and often difficult preparation to provide adequate bond strength between the FRP strip and the concrete substrate. This paper presents a feasibility study of an alternative method of attaching FRP strips to reinforced concrete...
The paper reveals about the Timber Bridge. The bridge is on a forest roadway and has the bridge length of 55.0 m with two continuous spans and the total width of 12.3 m with a 7.0 m two lane roadway and a 2.0 m one-side footway. The orthotropic steel deck...
