This research offers experimental and numerical study for the ultimate strength analysis and post buckling behaviour of plate girders subjected to shear and bending stresses. Two Plate girders of length 2.5m are designed consisting from three separate structural steel plates welded together to form I - section. The dimensions of the first girder section is 512 mm × 120 mm while the second girder section is 412mm × 120 mm. Mechanical properties for plate girders components were found by testing three samples of each plate. The ultimate shear strength was found by examining two plate girders in

Streszczenie:

Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web girders represent another two possible failure criteria. Here, the work previously performed by the author on corrugated web girders was compiled and presented in a comprehensive format. The starting point i

This paper presents a dynamic analysis of a long-span double-deck suspension bridge subjected to random traffic loading using a Finite Element (FE) model. During this study, the influence of various traffic parameters, such as vehicle speed, traffic volume, traffic weight, and the location of the passing girder, on the longitudinal movement of the girders was investigated. The results reveal that schemes with double girders passing can lead to greater longitudinal displacement of the girder as compared to a long-span bridge with a single passing girder.

Streszczenie:

Braces in straight bridge systems improve the lateral-torsional buckling resistance of the girders by reducing the unbraced length, while in horizontally curved and skew bridges, the braces are primary structural elements for controlling deformations by engaging adjacent girders to act as a system to resist the potentially large forces and torques caused by the curved or skewed geometry of the bridge. The cross-frames are usually designed as torsional braces, which increase the overall strength and stiffness of the individual girders by creating a girder system that translates and rotates as a

Abstract <strong>Background/Objectives:</strong> To professionally meet bridge load demands, hollow PC-girders are recently considered for bridge construction, particularly in Japan. Hollow girders are pretensioned girders, which can be a good alternative for ordinary PC-girders by having lightweight, using less material than other beams, and spanning long distances. Hollow PC-girders can be vulnerable to horizontal end cracking at the time of prestressing strand release. <strong>Methods:</strong> In this study, a nonlinear finite element analysis was performed to investigate th

Carbon fiber reinforced plastic (Carbon Fiber Composite Cable, CFCC) has the outstanding features in comparison with regular steel. In October 1988, CFCC was applied as the tensioning material in main girders of new Shinmiya Bridge in Ishikawa, Japan. This was the first bridge in Japan and in the world, which CFCC tendons were used in the prestressed concrete bridge to counter salt damage. To investigate the serviceability and durability of the main girders and CFCC, three full-scale test girders were fabricated in 1988.

AbstractIn recent years, steel-mixed composite structures have been widely adopted in China, especially in projects such as urban overpasses and viaducts where steel plate composite girder bridges are widely used. However, the research on small radius steel plate composite curved girder bridges is relatively limited, and the theory of structural stress characteristics and computational analysis is lagging behind. It is found that the radius of curvature has a small effect on the torsional stress of the bridge top plate, but the torsional stress of the steel main girder is higher; the torsional

<p>Longitudinal shear failure is a typical failure mode for composite girders. Based on experimental study, the finite element model was calibrated and numerical studies were carried out to analysis the longitudinal shear behaviour of high strength steel and concrete composite girders. It was analysed the effect of transverse reinforcement ratio, concrete strength, and steel grade on the longitudinal shear behaviour of high strength steel and concrete composite girders. Based on the current specifications, the transverse reinforcement area and longitudinal shear strength of the test gird

<p>Slender steel plate girders with deep webs provide flexural and shear strength to resist large loads. However, under shearing forces, web plates are susceptible to shear buckling. During the forming and fabrication of plate girders, initial out-of-flatness imperfections on the web plate are introduced and have demonstrated to reduce the shear buckling strength. Existing measures to enhance the shear buckling strength and improve the behavior of flat steel plate girders include welded stiffeners or corrugated web plate profiling. These methods introduce practical and fabrication challe

Streszczenie:

Corrosion in the girders of steel girder bridges often occurs due to the deicing salts, water, and other debris that leak through the deck joints into the web and bottom flange at the girder ends. Corrosion causes loss of cross-sectional area leading to a reduction in section properties of the member, which eventually results in a reduction in structural resistance against shear and bearing. In this study, seven full-scale tests were performed on decommissioned steel girders acquired from bridges scheduled for demolition in Indiana. Two of the four girders had severe corrosion with cracks and

Recent research results from INDOT research project SPR-4221 indicate that the damage to prestressed concrete bridge girders from an intense hydrocarbon fire is limited to concrete material degradation up to a depth of 1 inch from the surface. Additionally, concrete cracking and spalling occur in the fire-damaged region, but the structural strength (flexure and shear) of fire-exposed prestressed concrete bridge girders is not compromised. The findings open the possibility for repairing damaged bridge girders and answers questions regarding the durability of damaged-unrepaired and damaged-repai

As part of an inspection, bridge inspectors assign condition ratings to the main components of a bridge’s structural system and identify any defects that they observe. Condition ratings are necessarily somewhat subjective, as they are influenced by the experience of the inspectors. In the current work, procedures were developed for making inferences on the reliability of reinforced concrete girders with defects at both the cross section and the girder level. The Bayesian network (BN) tools constructed in this work use simple structural m echanics to model the capacity of girders. By using expe

The overall goal of this project was to investigate the role of torsional deformations and major axis bending deformations in lateral instability of long girders, specifically their effect on the theoretical buckling load. A closed-form solution showed that the torsional deformations do indeed reduce the buckling load below the value predicted by the present lateral-roll buckling model by an amount that can be captured with a “knockdown factor.” A numerical tool (ROLLBUCK) was also developed and checked against the closed-form solution for configurations that the latter could address. It was t

This project focused on evaluating the effects of fire-induced damage on concrete bridge elements, including prestressed concrete bridge girders. A series of controlled heating experiments, pool fire tests, material tests, and structural loading tests were conducted. Experimental results indicate that the portion of concrete subjected to temperatures higher than 400°C loses significant amounts of calcium hydroxide (CH). Decomposition of CH increases porosity and causes significant cracking. The portion of concrete exposed to temperatures higher than 400°C should be repaired or replaced. When s
