The traditional precast concrete column-to-column connections are widely used in the prefabricated frame structures China. However, many studies on joints have demonstrated their complex forms and poor construction efficiency. To overcome these shortcomings, a new type column–column connection with steel plate hoop bolts was designed proposed. In order to reveal seismic performance of this conn...

Sacro-iliac joint (SIJ) is the largest axial joint and is considered as a bottom joint of spinal column relating to the hip bones. It is a diarthroidial joint consisting of two types of articulation: (1) an antero-inferior synovial joint between the C-shaped auricular surfaces of the sacrum and ilium and (2) a postero-superior syndesmosis situated between the interosseous surfaces of the ilium ...

In order to realize the design concept of “strengthened column and weakened beam, strengthened connection joints components” ensure improvement joints’ bearing capacity transfer plastic hinges along beams far away from ends, this paper proposes a new type prefabricated with strengthen-weaken beam-column connection, changes multiple parameters. Six joint models are designed for finite element an...

Charcot spinal arthropathy is a rare, progressive type of vertebral joint degeneration that occurs in the setting of any preexisting condition characterized by decreased afferent innervation to the extent that normal protective joint sensation in the vertebral column is impaired. The authors report on a case of Charcot arthropathy of the lower lumbar spine mimicking a spinal tumor following cer...

Beam-to-column joints are one of the most common types in metal structures. In design load-bearing aluminium structures, welding, as a joining method, is often avoided because localised degradation mechanical properties heat-affected zone (HAZ). However, recent experimental studies on extent and strength HAZ show significant difference compared to very conservative rules when modern welding tec...
