In many regions of the world, a conventional low-ductility concentrically braced frame (CBF) is commonly chosen as seismic force resisting system. The energy dissipation not restricted to yielding and buckling braces, would be required for ductile frames; rather, assumed occur through localised friction in connections, well limited member yielding. objective this study was characterize by means...

To enhance the local buckling resistance of thin-walled steel pipes and their fire corrosion resistance, a new spirally stiffened square concrete-filled tubular laminated composite member with transverse ribs is proposed. Through four forms combined members for eccentric pressure testing, it was found that: ordinary pipe concrete drum more severe; spiral ribs, limited between stiffening ribs; d...

Fluted-core sandwich structures, consisting of fiber-reinforced plastics, are frequently utilized in the aerospace industry owing to their excellent strength-to-weight ratio. However, thin-walled structures prone local buckling, which reduces load-bearing capacity and eventually leads material failure. The current study presents analytical models for predicting buckling fluted-core panels subje...

Abstract In general, a web of the steel box girder is designed as an independent. However, in actual behaviour, since and flange behave couple, considered to have higher bending buckling strength than standard due restraint by flanges. Therefore, horizontal stiffeners for might be omitted. this study, focusing on effect coupled behaviour girder, FE analyses were carried out model with different...

Compared with traditional buckling-restrained brace (BRB), the steel-angle-assembled (SAA-BRB) is an innovative BRB light-weight, accurate control of geometrical dimensions, easy installation, and convenient disassembly. The SAA-BRB comprises external restraining system a cruciform-sectional inner core. Four steel angles assemble connection high-strength bolts, spacers are installed between cor...

Background The Maastricht brace (M-brace) was developed to improve compliance and associated efficacy of brace treatment in adolescent idiopathic scoliosis (AIS). Initial pressure measurements in the M-brace revealed a higher corrective pressure as compared to the Boston brace, and a better patient reported quality of life, as measured with the SRS 22 and Brace questionnaire. We present the fir...
