Bolted flange joints are commonly utilized in engineering constructions; nevertheless, their dynamic behavior is complicated when nonlinearity present. The bolted joint structure this research considered as a spring-mass system, and the equivalent axial two bi-linear springs-bending beam model, well system’s vibration control equation, created to examine structure’s characteristics under transv...

Elastic interaction effect commonly exists in the assembly of multi-bolted joint. It is defined as loss tension forces some bolts due to progressively tightening neighboring bolts. Main cable clamp a large size bolted joint used suspension bridge. Investigation on bolt has seldom been reported. This article presents field experiment study tightening. In experiment, three types and sequences wer...

Fatigue behavior of glulam moment resisting joint subjected to repeated cyclic loading has not been well clarified. In addition, the accuracy conventional design formulae for rotational stiffness and yield/ultimate should be discussed especially related method obtain material properties. this research, tests were conducted drift pined joints with insert-steel gusset plate tensile-bolted joint. ...

FastComp is a computational tool for the determination of the forces that a composite bolted joint subjected to multiaxial loads supports until failure occurs. The main intention of the present work was the development of a graphical user interface (GUI) for the referred tool that allows its parameterization and the visualization of its output results. Using VTK The Visualization Toolkit, a com...

In this paper, five sets of multi-bolted joint shear tests are designed to study the effect bolt middle distance on bearing performance joints, and analyze failure modes specimens. The main conclusions as follows: For M10 bolts (grade 8.8) bamboo curtain plywood connections. When spacing increases 50mm, ultimate capacity nodes tends be stable; initial stiffness joint, has no obvious joint. Howe...

In this research, the influence of bolt preload on the fatigue strength of 2024-T3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. To do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 N-m and then fatigue tests were conducted under various cyclic axial load levels. In the numerical method, th...

The vibration characteristics of bolted structures are crucially affected by the pre-tightening torque. An approach for identifying torque dependent stiffness parameters joints is proposed in this paper. Firstly, interface joint characterized thin layer element with isotropic material property, and parameter value property assigned relative to distance from center bolt; influence bolt ignored. ...
