Abstract Steel structures are severely affected by the extreme temperatures reached during a fire. After this, if structure has not collapsed, remaining elements can be reused they excessively distorted or material is still fit for service. In last case, residual properties of steel must adequate and fulfil requirements current standards. On this matter, it hypothesized that behaviour only depe...

Abstract In this study, the residual stresses were experimentally studied for cold‐formed square hollow section (CFSHS) with dimensions of 150×150×10 mm. The measured in both longitudinal and transverse directions S355J2H/S420MH S700MLH tubular sections. results showed that measuring on outer inner surfaces at a distance 60‐70 mm from end specimen is an accurate convenient method. For steel gra...

Wire arc additive manufacturing (WAAM) is a method of metal three-dimensional (3D) printing that has the potential for significant impact on construction industry due to its ability produce large parts with reasonable times and costs. However, there currently lack fundamental data performance structural elements produced using this manufacturing. Seeking bridge gap, compressive behavior resista...

The Welding in cold formed areas is not only an open question for statically loaded sections (brittle fracture) but also for dynamically loaded structures (fatigue resistance). A lot of structures are subjected to dynamic loadings and unfortunately very little information about the influence of welding in the cold formed areas on fatigue resistance is available. In order to establish the fatigu...
