A welded connection consists of three main material zones, the base (BM), heat-affect zone (HAZ), and weld metal (WM). The strength HAZ depends on BM grade manufacturing process, electrode grade, welding parameters. Under certain conditions, has lowest strength, especially for high-strength steel. Therefore, a semi-empirical methodology is proposed to establish constitutive model necessary pred...

Reliability is one of the main indicators structural elements mechanical safety. The choice stochastic models an important task in reliability analysis for describing variability random variables with aleatory and epistemic uncertainty. article proposes a method RHS (rectangular hollow sections) steel truss joints based on p-boxes approach. consist two boundary distribution functions that creat...

The primary focus of this investigation was to analyze sequentially coupled nonlinear thermal stress, using a three-dimensional model. It was meant to shed light on the behavior of Buckling Restraint Brace (BRB) elements with circular cross section, at elevated temperature. Such bracing systems were comprised of a cylindrical steel core encased in a strong concrete-filled steel hollow casing. A...

Abstract: In order to evaluate the capacity of RC members, the main codes allow the use of stress-strain laws that can reproduce closely the real behaviour of concrete, as opposed to parabola-rectangular or equivalent rectangular diagrams. Both sectional strength and ductility depend on the law of concrete, therefore they are influenced by the confinement of members, as evidenced in the literat...

Abstract The paper contains the results of an experimental investigation fatigue crack development under mixed-mode I + II and III in heat-treated 42CrMo4 steel. Tests were performed on compact tension shear specimens rectangular cross-section for III. Mixed-mode tests conducted 30 60° loading angle, while test was 45°. Additionally, presents fracture analysis path development.
