The article is aimed at the statistical and sensitivity analysis of the ultimate limit state of steel frames. Load–carrying capacity is calculated for steel plane frames with columns loaded in tesion or compression. The Monte Carlo based procedures are used for statistical analysis and for computing the full set of first order and second order sensitivity indices of the model. System imperfecti...

Computer modeling of the thermal behavior a thin-walled part made austenitic 316L stainless steel, grown by coaxial laser melting with variable and constant power, has been simulated. The conducted work was aimed at investigating effect number weld deposit layers studying influence bending radius in heat patterns growing zone, taking into account molten pool volume.

a r t i c l e i n f o Keywords: Concrete-filled steel tube (CFST) Confinement effect Fuzzy logic Modified learning from example (MLFE) Axial load capacity A circular concrete-filled steel tube (CFST) has several advantages compared with the conventional reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and str...

The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...

steel structures are usually built with some defects. according to the standard building codes, the central axes of the bracing members should go through the beam-column joints, however, in most of the braced steel structures, bracing members are unintentionally connected eccentrically. this paper presents a numerical investigation on performance analysis of cbfs (concentrically braced frames) ...
