Fiber-based computational modeling of rectangular double-skin concrete by Muhammad Rizwan, Qing Quan Liang et al

Both the external and internal thin-walled steel sections of a rectangular double-skin concrete-filled steel tubular (RDCFST) short column loaded axially may be susceptible to progressive local buckling, which is rarely included in mathematical modeling programs employing the fiber discretization scheme for such composite members. This paper provides a description of a new computational simulation technology, which is developed for the nonlinear fiber analysis of short RDCFST columns axially loaded to failure. The progressive localized-buckling failure of thin-walled steel sections are included in the formulation of the computational simulation method. Experimental measurements and finite element analysis results obtained by ABAQUS software by other researchers are employed to evaluate the accuracy of the computer algorithms developed. Numerical studies are undertaken to ascertain the responses of RDCFST columns to the change of design parameters. Proposed is a mathematical expression

How safe are our buildings?

A spate of fire accidents and building collapses in the last couple of months has raised serious concerns about the safety of buildings where we live and work in cities. On October 4, an eight-storey apartment in Shimla collapsed like a house of cards before the eyes of the residents who had luckily moved out noticing cracks in the building. In Bengaluru, two three-storey
