Present-day construction is greatly influenced by steel-concrete column composites. Steel-concrete composite gained extensive attention around the globe, which made utilization in more attractive than conventional reinforced cement concrete design. Different architectural culture has introduced inexhaustible diversification of different columns. One most widely used concrete-encased These colum...

Abstract: The study is to propose the local damage indices of composite frame structures consisting of high-strength concrete columns confined by continuous compound spiral ties and steel beams (CCSTRCS), the local damage indices would lay a foundation for the study of the overall damage indices for composite CCSTRCS frame. The Mehanny damage model has been modified to predict the local damage ...

The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...

The application of steel fiber reinforced polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing squ...

Composite foundation is a widely used treatment technology in geotechnical engineering. This study are derived governing equations to axisymmetric consolidation of unsaturated composite (USCF) incorporating permeable columns and impermeable under instantaneous loading, obtained the final solutions excess pore pressures (EPPs) by using mathematical methods such as variable separation, decoupling...
