Connections in Steel Structures III
Author: Reidar Bjorhovde
Publisher: Elsevier
ISBN: 0080529798
Category : Technology & Engineering
Languages : en
Pages : 635
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.

Analytical and Experimental Analyses of Selected 4-bolt Extended Endplate Moment Connections Subjected to a Tensile Load

Languages : en
Pages : 340
Book Description
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.

Low Cycle Fatigue Life Prediction of Four Bolt Extended Unstiffened End Plate Moment Connections

Book Description
The end plate moment connection has been studied with various design concepts. However the low cycle fatigue (LCF) analysis was focused after 1994 the Northridge earthquake because the connection failure mode of structure was not matched with the current design concept. This concept has been applied to the design of moment resisting frames and several research studies on the LCF behavior of various connections under cyclic loading have been conducted. While the research on the behavior of end plate moment connections (EPMC) under cyclic loading has been conducted very little information on the LCF behavior is available. To evaluate the accumulation of LCF damage, the LCF life prediction, three phases of experimental tests were conducted. In order to investigate critical geometric parameters for 4E EPMCs in the LCF behavior, parametric study was conducted with pre-qualified FEM model. In the first phase of the experimental test, total 4 reduced EPMCs, T-stub, was tested to verify the elastic range of the connection system and general behavior of the connection. Three different levels of constant peak displacement loadings were applied to three full scale EPMCs for developing a LCF model in second phase of the experimental test. In the last phase, an accumulated damage model was evaluated by one full scale end plate moment connection test using random loading. All of phases were adopted three-dimensional finite element numerical analysis, and theoretical analysis to predict the experimental behavior and it successfully anticipated the behavior of connection. The results of the experimental test developed the LCF model for 4E EPMC and it predicted the LCF life of connection. The parametric study determined the three critical geometry parameters.
