    Opis:
    Glass is used as an emerging structural member in the civil engineering construction industry. Fear and unconsciousness are the main hindrance to apply glass structure practically. Some safety glasses with the elastic interlayer material have the ability to carry higher loads than steel. So, it is high time to adopt this as a major load carrying structural member. At the beginning of this inspection elaborately presents the manufacturing process, basic properties and classification of glass for structural use. Reviewed portion of this work includes the recent research on the basic components of glass structure such as glass beam, glass column, glass slab or pavilion, glass walkway, glass panel, glass façade, curtain wall and glass frame under static or dynamic performances. The specific connection between glass with other materials and special types of different glass related composite structures like glass-concrete, glass-timber, glass-steel and glass-fiber are discussed. Special features of dynamic responses like effect of blast loading, wind born debris attack or cyclic loading and fire hazards of glass structure are also attached. Design guidelines and some practical applications are included to create interest, attention and courage for both structural engineer and architect. In recent years, a large number of glass related sophisticated developments have occurred in Europe. Since, An attempt has been taken to find out the huge research gaps in this sector so that this could fill in the future in order to spread glass design industry all over the world.

    Opis:
    Green high performance fiber reinforced cementitious composites (GHPFRCC) are a new class of sustainable cementitious composites, employing a high volume of fly ash to replace cement. In addition to increasing the sustainability of the construction environment, GHPFRCC exhibits a high tensile ductility and multiple cracking behaviors in the strainhardening state. These materials can effectively improve the structural energy dissipation capacity and structural durability. In this study, the optimum mixture ratio of GHPFRCC is presented established using an orthogonal experiment for a specific engineering application. The described GHPFRCC sustains the mechanical performance of concrete and is employed as the outer cladding to strengthen concrete columns. The finite element analysis of the material was based on the software ABAQUS and pseudo static experiments were conducted to exhibit retrofitting of GHPFRCC applied in the rehabilitation of seismic-damaged concrete columns. The computed and experimental results showed that GHPFRCC, while incorporating high volume fly ash, can retain significant multiple cracking behaviors. The energy dissipation capacity of the GHPFRCC reinforced concrete (RC) column is better than the comparable unreinforced column.

    Opis:
    To further optimise the bullet-proof performance of textile reinforced composites, multi-directional friction tests of aramid and ultrahigh molecular weight polyethylene (UHMWPE) yarns were carried out by the slope method. The influence of the included angle between the high-performance yarns on the static friction coefficient for aramid and UHMWPE yarns was studied by measuring the friction coefficient. The relationship between the static friction coefficient and the included angle among the high-performance yarns was discussed. The results showed that the friction coefficient of aramid yarns was higher than that of UHMWPE yarns. Especially, at the same included angle between high-performance yarns, the static frictional coefficient of aramid yarns is 50% higher than that of UHMWPE yarns. In accordance with expectations, the static friction coefficient decreases with the increased included angle between high-performance yarns, and the included angle of high-performance yarns changes from 0º to 90º. The trend of rapid decline appeared when the included angle between high-performance yarns changed from 0º to 15º. For the actual result, the static friction coefficient of aramid and UHMWPE yarns is less than 0.3, which needs to be improved to increase the bullet-proof performance of textile composites.

    Opis:
    The performance of buckling load of tubular structures under quasi-static axial loading is quite appreciable, numerous tubes of various cross-section have been extensively investigated and corrugated sections have been designed to further improve the performance. In this paper, a carefully designed set of key performance indicators (KPIs) is utilized to assess and compare the buckling load of circular and corrugated tubes. A series of diagrams related to KPIs with various parameters of tubes are presented to demonstrate the influence of sectional configuration on the performance of tubes as well as the effect of the material on the potential of the same. The work is inestimable to engineering designs and applications, and further studies on the buckling load of other configurations.
