The elliptical hollow section has been recently included in the family of structural steel sections. This type is also used production concrete-filled tubular (CFST) members. For CFST compression members, there no specific design formulation current provisions, except code called “Technical for structures” prepared by Ministry Housing and Urban-Rural Development People’s Republic China. However...

The use of concrete-filled steel tube (CFST) columns is highly encouraged nowadays in modern multistory structures. major reason the extensive resistance offered by hollow column to high compression. Nevertheless, further studies and data are desirable exhaustively characterize these members their connections other members, such as beams. This paper investigated behavior connected I-beams throu...

Emergency responders are faced with a number of significant challenges when managing major disasters. First, the number of rescue tasks posed is usually larger than the number of responders (or agents) and the resources available to them. Second, each task is likely to require a different level of effort in order to be completed by its deadline. Third, new tasks may continually appear or disapp...

Since laboratory tests are usually costly, simulating methods using computers always under the spotlight. This study performed a finite element analysis (FEA) iterative solutions for circular and square concrete-filled steel tube (CFST) columns infilled with high-strength concrete reinforced cross-shaped plate (comprising two plates along that divide hollow into four equal sections) without ope...

Abstract This paper studies the non-linear distribution of bond–slip behavior in steel concrete interface a Concrete Filled Steel Tube (CFST). Specifically, it concerns regions geometric discontinuity occurring composite beams CFST column-frame connection points. The study was conducted through an analytical model that represented bond stress transfer mechanism within these areas. resulting ded...

Concrete-filled steel tubular (CFST) columns have been assiduously investigated experimentally and numerically due to the superior structural performance they exhibit. To obtain best possible from CFST while reducing environmental impact, use of optimization algorithms is indispensable. Metaheuristic techniques provide designers members with a very efficient set tools design combinations that p...
