Abstract Composite sections are found to be a novel technique in modern day scenario of construction. This stands tall than the ordinary and conventional type constructions. Columns as structural element play vital role frame. research comments on behavior composite columns. The main objective this study is analyze steel-encased concrete columns experimentally under axial compression mode failu...

concrete filled steel tube columns (cfst) are a kind of composite columns according to advantages of cfst relative to reinforced concrete and steel columns. use of these materials is common in recent years especially in high building, unnecessary of molding, high ductility, proportionate resistance with low volume, economical, low deformation relative to steel columns are among advantages. in t...

The enhanced structural performance of Reinforced Concrete (RC) columns retrofitted by Fiber Reinforced Polymer (FRP) composite jackets, has been well demonstrated and an increasingly large number of bridge and building columns have been retrofitted with such jackets in the United States and elsewhere. However, seismic damage such as debonding between the jacket and the column that can consider...

As every card player knows, most existing card games share a large number of actions and situations. This is the case, for instance, for stacking cards in columns according to some allowed sequence or taking cards from a deal. This is true for both multi-player and solitaire patience games. Although they have such strong similarities, every game also has some peculiarity making it different, an...

A simple and inexpensive procedure used magnetite and levan to synthesize a composite recovered by a magnetic field. Lectins from Canavalia ensiformis (Con A) and Cratylia mollis (Cramoll 1 and Cramoll 1, 4) did bind specifically to composite. The magnetic property of derivative favored washing out contaminating proteins and recovery of pure lectins with glucose elution. Cramoll 1 was purified ...

Abstract This work is part of an effort to structurally integrate self-sensing functionality into smart composite materials using embedded microsensors and local network communication nodes. Here we address the issue of data management through the development of localized processing algorithms. We demonstrate that the two-dimensional fast Fourier transform (FFT) is a useful algorithm due to its...

Pultruded composite structural members with open or closed thin-walled sections are being extensively used as columns for structural applications l1Jhere buckling is the main consideration in the design. In this paper, global buckling is investigated and critical loads are experimentally determined for various fiber reinforced composite I-beams of long column length. Southwell's method is used ...
