Block shear failure of gusset plates with welded connections

2007-01-01
The mechanics of block shear failure in bolted connections has been studied extensively in the past. Current literature, however, lacks experimental evidence of the possibility of block shear failure in welded connection details. This study reports on the experimental testing of 11 welded gusset plate specimens which are subjected to tension. In the experimental program, the effects of connection geometry and weld group configuration were investigated. Test results revealed that block shear is a potential failure mode for welded connection details. The accuracy of the resistance equations provided by the design specifications were assessed on the basis of experimental findings. The experimental work is supplemented by nonlinear finite element analysis to predict the failure load of tested specimens. The load capacities obtained from the resistance equations and finite element analysis were all found to be conservative. The discrepancy between the test results and the predictions is explained in light of the presence of stress triaxiality. Finally, design recommendations are given based on the experimental and numerical findings.

Shear strength behavior of granular fill-clayey soil interfaces and improvement with dowels
Öztürk, Şevki; Ergun, Mehmet Ufuk; Department of Civil Engineering (2015)
Shear failures of interfaces between granular material and clay are frequently encountered in engineering practice. In earthfill dams, road embankments and spoil piles in mining operations, granular materials are placed on clay, and shear failures and/or large movements are observed along interfaces. When dealing with this type of a problem selecting representative shear strength parameters is difficult. Furthermore in the literature no accepted procedure is available to select these parameters. This study ...
Inelastic seismic response analysis and design of torsionally coupled systems
Kaatsız, Kaan; Sucuoğlu, Haluk; Department of Civil Engineering (2019)
Torsional coupling due to irregular placement of load resisting members and/or uneven mass distribution along a story plan is a very common phenomenon in structural systems. Unsymmetrical-plan buildings with stiffness and/or mass asymmetry behave considerably different compared to regular buildings when they are subjected to earthquake-induced forces. Modern earthquake resistant design related code provisions that employ capacity design principles aim to achieve a certain amount of ductility in the structur...
Scrap tire ring as a low-cost post-tensioning material for masonry strengthening
Türer, Ahmet (2008-10-01)
Load bearing walls of masonry type construction are weak in tension and wall failure in out-of-plane bending direction is one of the common failure mechanisms. Out-of-plane bending capacity and behavior can be greatly enhanced by post-tensioning. Developing countries commonly have poor and under educated population living in self-constructed masonry houses, which are at high risk if they are located on seismically active regions. Vast amounts of used tires, which contain steel-mesh and wires vulcanized with...
Interlaminar tensile strength and mode I fracture toughness of different angle-ply CFRP and GFRP composite laminates
Yavuz, Burak Ogün; Çöker, Demirkan; Department of Aerospace Engineering (2019)
Delamination is one of the main failure mechanisms in composite structures. Initiation and propagation of delamination are controlled by interface parameters including the interlaminar strength and fracture toughness, respectively. Hence, it is crucial to use the correct values of these parameters in the design and analysis of components such as composite tapered beams and curved beams. In this study, the effect of ply orientation on the interlaminar tensile strength and Mode I fracture toughness for CFRP, ...
Seismic retrofitting of highway bridges in Illinois using friction pendulum seismic isolation bearings and modeling procedures
Dicleli, Murat (Elsevier BV, 2003-07-01)
In this paper, the economical and structural efficiency of friction pendulum bearings (FPB) for retrofitting typical seismically vulnerable bridges in the State of Illinois is studied. For this purpose, a bridge was carefully selected by the Illinois Department of Transportation (IDOT) to represent typical seismically vulnerable bridges commonly used in the State of Illinois. A comprehensive structural model of the bridge was first constructed for seismic analysis. An iterative multi-mode response spectrum ...
