This paper studies structural behaviour of the blind bolted connections to concrete-filled steel tubular columns by a serial of experimental programs, which conducted involving eight sub-assemblages of cruciform beam-to-column joints subjected to monotonic loading and cyclic loading. The moment-rotation hysteretic relationships and failure models of the end plate connections have been measured and analyzed. A simplified analysis model for the blind bolted connections is proposed based on the component method. It is concluded that the blind bolted end plate connection has reasonable strength and stiffness, whilst the rotation capacity of the connection satisfies the ductility requirements for earthquake-resistance in most aseismic regions. This typed joint has excellent seismic performance, so it can be used in the moment-resisting composite frame.

Bolt Diameter

Bolted connections subjected to fatigue loading are usually considered to be the “weak point” in a design. They usually are highly preloaded to increase their resistance to external dynamic loading resulting in selecting large bolt diameters. This paper presents a design method for calculating an optimal bolt diameter required for a specific fatigue-loading situation. When load is applied to the bolted connection, the bolt tensile stress increases and the members undergo a decrease in compression. Based on the fact that the decrease in the deformation of the connected members must be equal to the increase in the deformation of the bolt, expressions are derived for maximum and minimum forces and stresses on the bolt. Using Soderberg’s failure line, an expression is developed for bolt diameter. It implies that there exists an optimal safe bolt diameter satisfying the loading conditions. Using a lower-bound value of bolt preloading produced an expression for the critical diameter of the bolt in terms of maximum and minimum dynamic force applied, the yield strength of bolt material, the factor of safety, and the stiffness constant. Examples are given to illustrate the design procedure.

Served as the primary form of joints in aluminum structures, the bolted connection is of great necessity to be investigated. The bearing performance of aluminum alloy bolted connections was evaluated by test and finite element (FE) analysis. A total of 20 bolted connections were tested and the varying parameters incorporated screw diameter and end distance. The test results included the ultimate bearing capacities and relationship between applied load and bolt hole deformation. Numerical simulation for the test process was implemented; thereupon reliability and accuracy of the FE models could be validated by good agreement with test results. By virtue of the verified numerical model, elaborated analysis of principle variables including inner and outer plies, end distance, screw diameter, sheet thickness and so on was carried out. Compared to the current overly conservative design rules, a new design method that could make full use of the bearing capacity was proposed. The corresponding design value of bearing strength was also presented with reference to the recommended constructional provisions.

3D Integer models of steel portal frames are made to analyze the influence of end-plate bolted connections on internal force and displacement of frames by using finite element method. The results show that end-plate bolted connections are semi-rigid connections, and the flexibility of the connections affects the behavior of the frames, and their influences can not be ignored in the steel portal frames design and analysis.
