This study investigates the strength enhancement of Tin Slag Polymer Concrete (TSPC) under hybrid GFRP and CFRP confinement in comparison with mono on TSPC circular short column samples. Hybrid FRP is prepared by wrapping followed both 1 layer using epoxy Sikadur 330 as matrix binders 50 mm overlap. Compression test was performed unconfined (TSPC-UC), (TSPC-GF), (TSPC-CF) (TSPC-HB) 1mm/ min loa...

Each year, massive amount of construction waste is generated that needs proper attention in terms its disposal without deteriorating surrounding environment. A significant portion this comprises bricks. Besides, large number new works are resulting the depletion natural resources rapidly. Intuitively, a sustainable solution demands to consume best way possible. This study targeted brick as pote...

System protection mechanisms such as access controls can be fooled by authorized but malicious users, masqueraders, and misfeasors. Intrusion detection techniques are therefore used to supplement them. However, damage could have occurred before an intrusion is detected. In many computing systems the requirement for a high degree of soundness of intrusion reporting can yield poor performance in ...

Advanced in vitro experimental tools for locally stimulating and probing brain slices can greatly facilitate systematic studies of neuronal phenomena and rapid drug screening. A major challenge in developing such tools is to achieve precise spatial and temporal control of local chemical environments of brain slices while maintaining their viability. This paper reports an improved design of a br...

The objective of this paper is to provide a brief overview of damage as observed immediately following the earthquake. Detailed studies of structural seismic performance, conducted in the time elapsed since August 1999, are not the subject of this paper, but rather the object of other papers presented in this Special Issue of the Journal. Damage to reinforced concrete, masonry, and steel struct...

Several structural failures occur in the columndue to lack of confinement. The circular column is not popular for regular buildings. use spiral only familiar tothe column. Many design engineers usesquare columns with hoops and cross tiesas As far as authors’ knowledge, therewasonly a study carried out on square columnswith spirals For this reason, authors propose introduce new type innovative c...

Received: November 11, 2016 Revised: January 26, 2017 Accepted: February 10, 2017 Abstract: Introduction: Square reinforced concrete (RC) columns with the confinement effect of transverse reinforcement perform well in ductility and have been used widely in RC structures. Its behavior is the classic topic of anti-seismic and anti-collapse analysis of RC structures. With the advancement of the fi...

In [Math. Meth. Appl. Sci. 19 (1996) 53-62], C. Marchioro examined the problem of vorticity confinement in the exterior of a smooth bounded domain. The main result in Marchioro’s paper is that solutions of the incompressible 2D Euler equations with compactly supported nonnegative initial vorticity in the exterior of a connected bounded region have vorticity support with diameter growing at most...

It is not unreasonable to expect that boreal forests which exist along 60 o N in the Eurasian and North American continents were created and are maintained by warm seasonal rainfall. As revealed from satellite observations and various precipitation sources, zonally elongated rainbelts appear along these forests. Previous studies show that a relationship may exist between the frontal zone along ...
