Parametric analysis of bolted flange connections of circular monopoles.
… (327 mm) circular pipe both welded to circular flanges. The outer and inner diameters of the flange plates were 327 mm and 171.5 mm respectively. Each bolt was 25.4 mm (1 in.) diameter and was pretensioned to 227 kN (51 kips); and an external load of 45 kN (10 kips) was applied at the free end …

Effects of shear deformations on the vibrational frequencies of wide-flanged structures
… the additional shear lag deformation of the flanges; thus, cross-sections of the beam are allowed to distort instead of remaining plane sections. The effect of relative flange bending (bending of the flanges relative to the web) is also included and the integro-differential equations …

Beam behaviour of hybrid steel sections
… development of stresses and strains within the flanges and web in order to establish how this differs from that in homogeneous members. It was also necessary to investigate the effectiveness of various hybrid combinations (with steels of varying yield strength in webs and flanges), the influence …

An investigation into the role of hydrogen embrittlement in the formation of split bodies in two-piece food cans
… that cause 2- piece food cans to fail is split flanges. Split Flanges arises due to a number of reasons which will be discussed in detail.The focus of this thesis was based on the causes of split flanges in 2-piece food cans. A study on manufacturing the steel and can making together with …

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures
… series to study the effect of the beam's top flanges within the connection. One of the most important mechanisms of shear transfer proved to be the top flanges of the precast beam. For the precast beams with top flanges (first series), and with a 300mm beam embedment length, it was discovered …

Development of Small-Footprint Large-Amplitude Tripod (three lambda) Mode Traveling Wave Generator
… cylindrical stub vibrators without and with end flanges have been investigated by means of computer simulation and experiment, with the aim of generating a traveling wave of three lamda mode shape (i.e. of three crests and three troughs) along the circumference of both end faces to provide …

Analysis and design of composite curved frames
… in the curved corner regions between the web and flanges and at the free edges of the flanges. A response surface design approach is used to approximate the failure response using a minimum number of finite element analyses. Large degree of freedom 2D/3D global/local finite element models are …

Web crippling behaviour of cold-formed steel sections with circular web openings under one-flange loading
… (EOF) loading condition; the cases of both flanges unfastened and flanges fastened are considered. In the case of the tests with web openings, the holes are located either centred above the bearing plates or with a horizontal clear distance to the near edge of the bearing plate. …

Cortante longitudinal em vigas de concreto com mesas comprimidas
… in beams of reinforced concrete with compression flanges. It is included a brief summary of the design methods and tests published earlier, and also the recommendations of some codes of practice related to the subject. For the experimental study five T-beams were tested. These beams were simply …

Numerical and experimental methods for seismic risk assessment of civil and industrial structures
… plants. Although tanks, pipes, elbows and bolted flanges have been a major concern in terms of seismic design, generally, they have not been analysed with modern performance-based procedures. This thesis will explore some important themes in seismic risk assessment with a special focus on …

Machine design to improve accuracy and repeatability in on-site circular milling
… is used in the finishing and repairing of flanges most commonly used for mating with slewing bearings. The expected outcomes of the manufacturing processes are always increasing, therefore requiring higher levels of accuracy. The milling must be performed under a wide range of environmental …

Seismic Evaluation of Welded Moment-resisting Connections
… as a suitable type of weld for welding beam flanges to the column flange in seismic areas. New Zealand’s steel design standard is the only standard that allows using fillet welds for the fabrication of welded connections in high seismic zones. However, NZS 3404 standard employs an …

An Investigation of Classical Panel Stiffener Buckling Methods for Modern Airframe Applications
… of aircraft panels reinforced by bulb-stiffened flanges differ regarding symmetric versus asymmetric cross-sections. The present research addresses a number of classical derivations of methods with a focus on the work of Dwight Windenburg as published in "The Elastic Stability of Tee Stiffeners" …

Failure and crippling of graphite-epoxy stiffeners loaded in compression
… Seventeen specimens exhibited local buckling of flanges and webs prior to failure, four exhibited global column buckling prior to failure, two exhibited material short column failure, and one exhibited unstable postbuckling behavior prior to failure. The buckling loads for each specimen were also …

Classification of underwater pipeline events using deep convolutional neural networks
… inner coating exposure, presence of algae, flanges and concrete blankets. Such inspections might benefit of machine learning techniques in order to accurately classify such occurrences. In this work, we present a deep convolutional neural network algorithm for the classification of …

Evaluation of redundancy in trapezoidal box-girder bridges using finite element analysis
… result in the collapse of a bridge. The tension flanges of twin box-girder bridges are thus labeled as fracture-critical. In order to avoid the catastrophic collapse suggested by the AASHTO specifications, fracture-critical bridges, constituting 11% of all steel bridges in the country, are …

Development of a Novel Cold-Formed Steel Truss System
… (HCs), which is U-shaped (short web with long flanges) that is specially manufactured to accommodate HRC through flanges. Different sizes of HRC joints (Tee-stubs) were tested under tension load. It was then compared to bolted Tee-stubs. It was found the HRC and bolted Tee-stubs have similar …
