The design rules for centrically compressed stainless steel equal-leg angle members are not explicitly stated in the current European standard SRPS EN 1993-1-4. This paper summarizes results of extensive research conducted on this type structural elements aiming to define recommendations their design. Based a systematic experimental investigation, detailed numerical analysis was performed, and ...

Although nickel–titanium (NiTi) rotary files are invaluable tools in dentistry, the relationship between their properties and performance has not been elucidated. Herein, of gold heat-treated (ProTaper Gold ProfaTaper Gold), controlled memory (CM)-wire (HyFlex CM V Taper 2H), T-wire (2Shape), R-phase (K3XF) NiTi was evaluated; non-heat-treated ProFile used as control. The bending, buckling, cyc...

Cold-formed steel members are usually used as purlins in buildings to support roof cladding and thus they can be treated beams restrained fully or partially the lateral torsional directions. However, when these subjected wind suction loading, their free flange is compression, which may cause web–flange distortional buckling (WFDB). This paper presents an analytical study on WFDB of zed-section ...
