2093) Research on High Tensiles Bolt Friction Joint : Experimental Study for Single Shear Joint(Structure)

Experimental Study on New-typed Prefabricated Shear Walls with Vertical Joint Under Different Shear Span Ratio

The results show that the shear span ratio has significant effect on the mechanical behavior of the new-typed prefabricated shear walls, and the new-typed prefabricated shear walls have good ductility, all the ductility factors are greater than 4.0. The study also proves that the construction of the vertical joint is reasonable and its connection property is reliable. The vertical joint which c...

The Effects of Bolt Spacing on Composite Shear Wall Behavior

Composite steel shear wall is a lateral load resisting system which consists of a steel plate with concrete wall attached to one or both sides to prevent it from elastic buckling. The composite behavior is ensured by utilizing high-strength bolts. This paper investigates the effect of distance between bolts, and for this purpose 14 one-story one-bay specimens with various bolts spacing were mod...

Novel experimental techniques for investigating time resolved high speed friction

The paper presents some recent advances in experimental methods to investigate the phenomenon of high speed friction. In particular, Ž . Ž . two novel experimental methods are employed in the present study: a the plate impact pressure–shear friction experiment, and b the torsional Kolsky bar friction experiment. Using these experimental configurations, dynamic frictional characteristics of Carp...

Experimental Study on Low Velocity Friction Compensation and Tracking Control

Stick-slip phenomenon is often associated with the control of low velocity motion because of the positional dependancy of friction and negative damping friction that decreases as the motion speed increases. In this paper, smooth low velocity tracking control of a commercial robot joint is demonstrated experimentally using a combination of high gain PID control, fast sampling rate and high posit...
