Eurocode 3 establishes the component method to analytically characterize the structural joints between beam and columns. When one of the members involved in the joint is a hollow section (i.e., a tube) there is a lack of information for the specific components present in the joint. There are two different ways to bridge the gap: experimental testing on the actual beam column joints involving tu...
space 1 The space of twist Joint space The space of wrench (6) jT T T J ~ ( = J KI Ii) I ' * 1 v torque space 1 Figure 2.6: Transformation from Task Domain to Joint Domain where each column of J is the image in abstract space of the corresponding column of the Jacobian J . Thus. the base of the joint variable space is: and the base of the joint torque space is: Because J is a matrix defined in ...
A detailed nonlinear finite element model was established based on completed experiments to investigate the behavior of a blind-bolted T-stub composite joint that connects beam concrete-filled square tube column. This accomplished by comparing experimental results and simulation using hysteresis curve, failure mode, plastic deformation strain development ensure reliability accuracy model. param...
This study developed a 1:2 scale model using T-shape steel with one-side bolts to connect square tube column an H-shape beam for quasi-static test investigate the mechanical properties and seismic behavior of semi-rigid joints. Within context, joint’s failure characteristics, hysteresis strain tendency under cyclic load were determined. In addition, this research analyzed force characteristics ...
The present study describes the structural performance of a soft-first-story column-beam joint with mechanical anchorage column longitudinal rebar. A new strengthening method using reinforcement is presented to prevent brittle failure in this type structure. series static loading tests was conducted two scaled models representing above verify effectiveness proposed strengthening. test results c...
This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...
The aim of this study was to characterize the individuals with sacroiliac joint bridging (SIB) by analyzing the degenerative changes in their whole vertebral column and comparing them with the controls. A total of 291 modern Japanese male skeletons, with an average age at death of 60.8 years, were examined macroscopically. They were divided into two groups: individuals with SIB and those withou...
