Book Description
This book publishes the proceedings from the Third International Workshop on Connections in Steel Structures: Behaviour, Strength and Design held in Trento, Italy, 29-31 May 1995. The workshop brought together the world's foremost experts in steel connections research, development, fabrication and design. The scope of the papers reflects state-of-the-art issues in all areas of endeavour, and manages to bring together the needs of researchers as well as designers and fabricators. Topics of particular importance include connections for composite (steel-concrete) structures, evaluation methods and reliability issues for semi-rigid connections and frames, and the impact of extreme loading events such as those imposed by major earthquakes. The book highlights novel methods and applications in the field and ensures that designers and other members of the construction industry gain access to the new results and procedures.

Book Description
This study is a pioneer in introducing the circular bolt pattern configuration in extended endplate steel connections. Discovering the static and cyclic behavior of such connections is at the forefront of this research study. To accomplish this goal, full-scale experimental testing complemented with three dimensional non-linear finite element analysis was conducted. Due to the similarity between the behavior of T-Stubs under tension, and tension flange of the extended end-plate connection, experimental study was conducted on several T-Stub connections to study the effect of the bolt pattern configuration on the ductility, bolt force distribution, flange deformation, and overall performance of the connection. The specimens were fabricated in the laboratory and the bolts were strain gauged to monitor the bolt force during testing. This experimental study was coupled with nonlinear finite element modeling for further validation of the FEM results. Three-dimensional non-linear finite element models were developed for each case using the corresponding geometric values. The steel plates were modeled with 8-noded linear brick, reduced integration, and hourglass control element. Six-noded linear triangular prism elements were used to model the bolts, bolt head, nuts, and the washers. The combined hardening plasticity algorithm was used in order to model the behavior of the Grade-50 hot-rolled steel elements during monotonic and cyclic loading. Isotropic hardening was used to model the material properties for the high strength steel bolts. Small sliding surface-to-surface contact algorithm was considered for all the contacts. The welds were modeled by a tie-contact algorithm. The frictional surfaces accompanied by tangential forces were modeled by a tangential-contact algorithm. The contact surfaces between the end-plate and column were modeled by the frictional contact using the penalty method. One hundred eighty two numerical models with circular and square bolt patterns were developed and analyzed by using the developed FEM. A comprehensive test matrix was used to investigate the effectiveness of the various geometric parameters on the overall behavior of the connections. The parametric study included seven bolt diameters, six values of end-plate thickness, three beam sizes, and two different bolt pattern configurations based on the most commonly used range of variables. The numerical results of the connections with circular bolt pattern were compared with that of the connections with traditional square bolt pattern. Also, the effects of these parameters on the moment-rotation characteristics and energy dissipation of the connection were investigated. To simulate the hysteresis behavior of the connection (i.e. energy dissipation), four parameter tri-linear hysteresis models were used to fit the outer loops of the moment-rotation hysteresis loops obtained from the FEM experiments. Comprehensive regression analyses were conducted to obtain equations for dependent variables (tri-linear model parameters) in terms of independent geometric variables.) The results of this study show that the circular bolt pattern can enhance the moment capacity, reduce pinching, and ultimately increase energy dissipation of the connections depending on their geometric parameters.

Book Description
Moment end plate connections have found their usage in a number of applications and extensive research has been done on smaller capacity connections of such type. This study seeks to investigate the failure mechanism and the subsequent prediction of the moment capacity of a ten bolt flush end plate connection. The model under study is typical of a flush end plate connection present in an existing steel parking deck. Yield line analysis methods have been employed in analyzing the various failure mechanisms and have been used in developing prediction equations for the design of the end-plate. The modified Kennedy method has also been used in the prediction of the bolt forces for all cases of the analysis with failed bolts. A three dimensional finite element model using ABAQUS Standard has been employed to validate the results from the analytical methods taking into consideration, the interactions between the connection components, boundary conditions and material non-linearities. The moment capacity and the corresponding failure mechanism is predicted under two cases of bolt loss in rows of the connection. Limit state of end plate yielding governs the design for the ten bolt connection and that with one row of bolt failure at the top. Bolt fracture governs the design when there are two rows of failed bolts.
