This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Develops three-dimensional solid finite element models to study the behavior of large capacity eight-bolt extended unstiffened wide endplate steel connections, using current-technology elements instead of legacy elements. Uses a finite element software package (ANSYS, version 11.0) to create and analyze three finite element models. Uses eight-node brick solid elements to model the connection numbers with the exception of the bolt shank, which uses one three-dimensional spar element for modeling.

Available in PDF, EPUB and Kindle. Book excerpt: Distortions from gas metal arc (GMA) multipass welds of thick steel plates were measured in experiments and calculated using finite element analysis. Two- and three-dimensional finite element simulations were compared with the experimentally measured in-plane distortions in a 2-3/4 in. thick steel plate. Thermal analyses were performed using 2D models of the weld cross-section. These temperature histories were used for 2D and 3D mechanical analyses. Data for verification of thermal analyses included weld cross-sections, weld pool crater shape from power-off tests, and embedded and surface thermocouple temperature histories. Mechanical analyses were verified using caliper measurements of shrinkage transverse to the weld and strain gage measurements. Calculated in-plane shrinkage from the 3D model for 4 passes compared well with caliper measurements of a test specimen's distortion. Two-dimensional mechanical analyses were not capable of predicting the accumulation of shrinkage occurring after the first pass.

This book was released on 2003 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the present research project was to experimentally and analytically determine the validity of a pure tension design approach to the 4-bolt moment procedure. To achieve this, the effects of end plate thickness and stiffener plates were investigated by testing three connection types and modeling these connections using ANSYS 6.1. Experimental testing included instrumentation of the specimens consisting of strain gages and displacement transducers. A constantly increasing tension force was applied to the specimens using an 860 kip hydraulic cylinder. At 860 kips (which represented a 3.88 increase beyond the design load of 221.41 kips), none of the specimens failed, although large plastic deformations were observed. Clear differences were observed in the elastic/plastic behavior, deformation and stress levels in the three specimen types. It was concluded that the specimen with a 3/4" end plate and welded stiffeners was clearly the stiffest specimen of the three combinations tested. ANSYS 6.1 was used to perform finite element analyses on both the stiffened and unstiffened 3/4" end plate connections. A comparison was made between both 3/4" end plate connections. In general, analytical findings corroborated experimental results and were, on average, within 10% of those found experimentally. The use of stiffeners welded between the end plate and the beam section greatly enhanced the tensile behavior of the connection. In fact, the stiffened end plate connection outperformed the end plate connection with the required thickness.
