Experimental and numerical investigations were carried out on adhesively bonded full-scale double lap joints from pultruded GFRP profiles with relatively thick adhesive layers, needed in infrastructure applications to compensate for tolerances. The influence of different geometrical parameters on the joint strength was investigated, namely the thickness of the adhesive layer (from 5 to 35 mm), ...

Glass Fibre Reinforced Polymer (GFRP) composite wrap has become an effective repair system for deteriorated structural columns. It is essential to provide infill material in the gap between retrofitted column and GFRP wrap. So, properties of can significantly influence contribution these wraps thus, affect overall performance structure. However, research on effect confinement materials with var...

Steel structures are becoming more common in engineering construction as steel possesses excellent ductility, but members often vulnerable to buckling, especially under seismic or cyclic loading. Hollow structural sections (HSS) buckle locally loading due their thin walls and the need for rehabilitation strengthening is increasing. In present study, circular hollow section (CHS) have been stren...

‎Let $tau$ be a subgroup functor and $H$ a $p$-subgroup of a finite group $G$‎. ‎Let $bar{G}=G/H_{G}$ and $bar{H}=H/H_{G}$‎. ‎We say that $H$ is $Phi$-$tau$-quasinormal in $G$ if for some $S$-quasinormal subgroup $bar{T}$ of $bar{G}$ and some $tau$-subgroup $bar{S}$ of $bar{G}$ contained in $bar{H}$‎, ‎$bar{H}bar{T}$ is $S$-quasinormal in $bar{G}$ and $bar{H}capbar{T}leq bar{S}Phi(bar{H})$‎. ‎I...

In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to th...

This paper focuses on the compressive strength of Glass fiber reinforced polymer (GFRP)-confined concrete columns. Data from 114 sets GFRP-confined columns were collected to evaluate researchers’ and proposed model. A data-driven machine learning model was used investigate importance sensitivity parameters affecting strength. The results show that facilitates study confined but suffers a large ...
