“…In this regard, they incorporated substructuring techniques and fnite element methods. Skalomenos et al [11] presented an experimental investigation on the material properties of induction heat (IH) treated with steel elements used in BIEs. Tey used IH treatment and applied it to one-half of the cross-section to enhance the strength of that part, while the remaining part had the conventional properties of steel.…”

Seismic Behaviour of Multistorey Steel Framed Tall Buildings Using Intentionally Eccentric Braces

Braces with intentional eccentricity (BIE) are recently proposed to improve the seismic behaviour of conventional buckling braces (CBBs) by inserting intentional eccentricity along the brace length. Due to this eccentricity and the resultant bending moment, the BIE bends uniformly from small storey drifts and moves smoothly into the postbuckling behaviour under compression and sustains trilinear behaviour under tension. This behaviour delays the appearance of midlength local buckling which causes unstable energy dissipation. BIEs have a desirable postyielding stiffness which results in stable energy dissipation during cyclic loading and are capable of dissipating energy during low-intensity earthquakes. The seismic behaviour of structures with BIEs for use in buildings has not yet been investigated, specifically in tall buildings. Therefore, this study concentrates on investigating the seismic behaviour of tall buildings equipped with BIEs that uses a 3-dimensional (3D) finite element model in ETABS. In the first step, a 20-storey structure is designed using both eccentric brace frame (EBF) and BIE system and their seismic performance under the TABAS earthquake record is compared. In the second step, the seismic performance of a 25-storey irregular structure is assessed to evaluate the efficiency of the BIE system in irregular structures. Results show the desirable performance and energy dissipation capacity of the BIE system but it also shows large out-of-plane deformation in some cases.

“…At the same time, the surface hardness that can be achieved is higher, and it is easier to meet the needs of actual production. In recent years, due to the many advantages of induction hardening, the use of induction hardening in the industry has increased [1,2]. Induction hardening can produce a hardened layer on the surface of the workpiece to achieve the purpose of improving the surface properties, such as wear resistance and hardness of the workpiece [3].…”

This paper focuses on the study of the induction heating process of a camshaft in a marine diesel engine. A three-dimensional finite element model for dynamic induction heating is established using the finite element method of multi-physical field coupling, aiming to investigate the temperature uniformity of the cam during this process. Three elements are analyzed in this study: the moving speed, the gap between the induction coil and the workpiece, and the width of the induction coil. These factors allow for an analysis of the temperature distribution in the thickness direction and contour line direction of the cam under various conditions. On this basis, an equivalent parameter about the temperature uniformity in the thickness direction of the cam is proposed to guide the selection of the camshaft induction heating process parameters.

“…Recent works [20,21] have focused on slenderness effects of the NBBs under seismic loads and effects of far-field and near-fault cyclic loads on seismic performance of braces demonstrating their efficiency in various built-up rectangular steel sections and chevron configurations. The design concept of the combined axial-flexural behaviour of braces has also been recently validated in uniform circular steel sections where the target material contrast was achieved by utilizing the induction-heat treatment technology for the one half of the section [22,23].…”
