An attempt has been made to use this composite structural member as a column with a modification of flutes on the steel tube which enhances the aesthetics and development area of sheet by which the moment of inertia gets increased by about 17 to 40 % for rectangular flutes and 9 to 23 % for triangular flutes. Confining concrete by providing triangular and rectangular shape fluted steel tube has...
This paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (CCFST) stub columns under axial loading condition based on Artificial Neural Networks (ANNs) by using a large wide of experimental investigations. The input parameters were selected based on past studies such as outer diameter of column, compressive strength...
Concrete-filled steel tube (CFST) columns have been widely used in onshore constructions. To extend its applications to coastal/offshore structures and meanwhile relieve the overexploitation on freshwater river sand, an FRP-confined seawater sea-sand concrete-filled stainless (F-SSCFSST) column is proposed. The cyclic axial compressive behavior of this newly proposed was investigated study. A t...
A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite element analyses of FRP-strengthened RC slabs. The layered approach is used to form an integrated plate element for modelling of concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer. Timoshenko’s composite beam functio...
Revised code of earthquake-resistant building design from SNI 1726:2012 to 1726:2019 as a result changes in the earthquake magnitude that occurred recent years and developments engineering research resulted many structural elements should be strengthened, especially on column elements. One most adopted strengthening techniques for enhancing performance existing RC columns consists wrapping memb...
