The exceptional structural strength and low cost of steel-concrete composite columns make them a popular choice for civil engineering structures. Numerous forms columns, including steel tubes filled with concrete, have been produced recently in response to various construction situations. Cold-formed tubular concrete filling higher ductility due their capacity withstand inner buckling postpone ...

Honeycomb cores are widely used in the aerospace and automotive fields as a part of protective structures. Unfortunately, standard prismatic honeycomb offer limited amount energy absorption under lateral loads suffer from degradation their impact-deadening properties when dimensional scale is increased. In this work, multiscale study on quasi-static load carried out 3D-printed core samples cons...

This paper studies the behavior of axially loaded RC columns which are confined with carbon fiber reinforced polymers’ sheet (CFRP) and steel jackets (SJ). The study is based on twelve tested up to failure. It divided into three schemes its strengthening type; each scheme has four columns. main parameters in this were compressive strength concrete reinforcement ratio. Furthermore, results exper...

Sandwich tube structures bio-mimicking horsetail and human tendons offered significant improvement over traditional single multi-cell tubular energy absorbers. The present research aims to investigate three manufactured hybrid aluminum GFRP sandwich tubes subjected quasi-static low-velocity axial compression. crashworthiness characteristics crushing failure mechanisms of are discussed compared ...
