Book Description
A truss joint, one of the most fundamental joints used in civil engineering, has been used in bridge and building structures since the invention of truss technology. Initially, the material of choice was first wood and then steel. With the invention of composite materials, tests have shown that these new composite materials will soon become the materials of choice for these structures. The advantage is a lighter weight material and stronger mechanical properties. These composite materials are already extensively used for aviation and marine structures. Trusses with composite joints will soon be a standard for all aviation and marine structural components. In the research for this thesis, 2- Dimensional and 3-Dimensional tubular Pratt truss structure joints are addressed, with finite element analysis (FEA) applied to determine the loads on each joint tube. Model geometry design and FEA static analysis is performed using Solidworks computer aided design (CAD), and Solidworks finite element (FE) Simulation. Data is generated experimentally by measuring the mechanical behaviors, e.g., stress, strain, and displacement that are exhibited in the joints when the tubes are loaded. Hand molding technology is used as a fabricating method on test articles. A comparison of CAD FE simulation results, and results of tension and compression tests, are carried out on composite joints manufactured by hand molding techniques to validate the design process. For the "T" joint test articles, the prediction tensile load for laminate failure is 194 kN; the prediction compressive load for laminate failure is 173 kN. For 45° test articles, the prediction tensile load and compressive load for laminate failure are 191 kN and 170 kN. The prediction maximum load for cohesive failure is 150 kN. The predicted adhesive failures were obtained in the physical tests. The maximum load for adhesive failure achieved from physical test was 20 kN while the prediction maximum load for adhesive failure was 50 kN. Increasing boding area and better bond surface will yield higher and more consistent bond strengths.

Book Description
This book details the basic concepts and the design rules included in Eurocode 3 Design of steel structures: Part 1-8 Design of joints Joints in composite construction are also addressed through references to Eurocode 4 Design of composite steel and concrete structures Part 1-1: General rules and rules for buildings. Attention has to be duly paid to the joints when designing a steel or composite structure, in terms of the global safety of the construction, and also in terms of the overall cost, including fabrication, transportation and erection. Therefore, in this book, the design of the joints themselves is widely detailed, and aspects of selection of joint configuration and integration of the joints into the analysis and the design process of the whole construction are also fully covered. Connections using mechanical fasteners, welded connections, simple joints, moment-resisting joints and lattice girder joints are considered. Various joint configurations are treated, including beam-to-column, beam-to-beam, column bases, and beam and column splice configurations, under different loading situations (axial forces, shear forces, bending moments and their combinations). The book also briefly summarises the available knowledge relating to the application of the Eurocode rules to joints under fire, fatigue, earthquake, etc., and also to joints in a structure subjected to exceptional loadings, where the risk of progressive collapse has to be mitigated. Finally, there are some worked examples, plus references to already published examples and to design tools, which will provide practical help to practitioners.

Book Description
The growing use of composites over metals for structural applications has made a thorough understanding of the behaviour of composite joints in various applications essential for engineers, but has also presented them with a new set of problems. Composite joints and connections addresses these differences and explores the design, modelling and testing of bonded and bolted joints and connections. Part one discusses bolted joints whilst part two examines bonded joints. Chapters review reinforcement techniques and applications for composite bolted and bonded joints and investigate the causes and effects of fatigue and stress on both types of joint in various applications and environments. Topics in part one include metal hybridization, glass-reinforced aluminium (GLARE), hybrid fibre metal laminates (FML), glass fibre reinforced polymer (GFRP) and carbon fibre reinforced polymer (CFRP) composites. Topics in part two include calculation of strain energy release rates, simulating fracture and fatigue failure using cohesive zone models, marine and aerospace applications, advanced modelling, stress analysis of bonded patches and scarf repairs. Composite joints and connections is a valuable reference for composite manufacturers and composite component fabricators, the aerospace, automotive, shipbuilding and civil engineering industries and for anyone involved in the joining and repair of composite structures. Explores the design, modelling and testing of bonded and bolted joints and connections Reviews reinforcement techniques and applications for composite bolted and bonded joints Investigates the causes and effects of fatigue and stress on bolted and bonded joints in various applications and environments
