Cable-net structure supported glass facades have been widely used as modern building facades in airports, hotels’ lobby and for the constructions that require a high aesthetic value in terms of appearance. Most of the researchers have neglected the contribution of glass on the stiffness of the cable-net structure. However, glass panels play an important role in the stiffness of the cable net structure when there are damages in cables. This study was carried out to determine the contribution of glass to the stiffness of damaged cable-net structure under static and dynamic loadings. The cable was subjected to 30%, 60% and 100% losses of the initial pre-stress in the cable. The glass stiffness contribution was determined from the deflection and natural frequency of the cable-net structure with and without glass panels under static and dynamic loadings. The glass panels have shown a significant contribution to the stiffness of the cable-net structure with damaged cables.

This research is aimed at investigating the dynamic behaviour of, and to analyse the dynamic response and dynamic performance of steel frames strengthened with welded haunches subjected to a typical hydrocarbon blast loading. The structural dynamic analysis was carried out incorporating the selected blast load, the validated 3D model of the structures with different welded haunch configurations, steel dynamic material properties, and non-linear dynamic analysis of multiple degree of freedom (MDOF) structural systems. The dynamic responses and effectiveness of the reinforced connections were examined using ABAQUS finite element software. Results showed that the presence of the welded haunch reinforcement decreased the maximum frame ductility ratio. Based on the evaluation of the results, the haunch reinforcements strengthened the selected steel frame and improved the dynamic performance compared to the frame with unreinforced connections under blast loading, and the biggest haunch configuration is the “best” type.

Structural glass facades or cable-net supported glass façade has been widely used as a modern building facade in engineering construction for a long-span greater than 7 m because of their simple, light and transparent appearance of the structure. With these advantages make them dominant in various applications especially for the building that emphasize the high aesthetic value in term of appearance and also a large space such as airport, hotel and many more. In this research, the damages of cable-net structure were investigated for both with and without glass panels under static behaviour. Three type of damages were considered in this research which are failure of cable connector between two intersection of steel wire cables, different percentage of cable pre-stress losses which are 30 and 60% loss and lastly is cable end anchorage failure with the 100% loss of cable pre-stress force. The deflection of the cable-net with and without glass panels is used to determine the contribution of glass stiffness to the cable-net structure. The cable connector failure shows a little effect rather than the cable failure which are cable pre-stress losses and cable end anchorage failure to the performance of the cable-net structure.

Glass that used for architectural and structural purpose will undergo long term exposure to the natural outdoor environment. Exposure to outdoor weather such as temperature, humidity, UV-radiation, pH, etc. may cause deterioration of glass strength. This paper aims to study the effect of short-term exposures to natural outdoor environment on the strength of glass panel. Four sets of tempered glass samples were prepared for direct exposure to the outdoor environment. The samples were exposed to the outdoor environment for 40-, 80- and 120-days. A total of two tests namely microscopic observation on glass surface and four-point bending test on glass panel were conducted. Based on microscopic observation, the intensity of surface defects such as surface scratches, bubbles, and dust were increased for longer period of outdoor exposure. The bending and residual strengths of the glass panel reduced as the duration of the outdoor exposure was increased. The tempered glass material tends to undergo deterioration in strength by weathering process.

Concrete cover plays an important role in protecting the reinforcement from harmful environments and high temperatures. In this study, the effects of the concrete cover containing garnet and rebar prepared with cover thicknesses of 20 and 30 mm and subjected to temperatures of 20°C, 200°C, 400°C, 600°C and 800°C for 1-hour duration were determined by conducting ultrasonic-pulse velocity and tensile tests. The results of the study show that concrete specimens with cover 30 mm protect steel completely before they disintegrate, almost up to 300°C and by replacing sand with 40% of garnet, gives significantly better fire resistance than normal concrete.

Multi-bolted joints are adopted and designed to provide efficient load transfer within assembled engineering parts. Bearing failure is favorable during design phase due to more progressive failure mode, however, ability of by-pass stress to be transferred to adjacent bolts in multi-bolted joints prone to catastrophic net-tension failure. Former approach known as equivalent spring stiffness (ESS) was proposed but it requires experimental sliding load value. This has led to semi-empirical approach to require experimental set-up than incorporating a generic bolt preload value. This paper aims to provide a unified bolt preload (UBP) value to be implemented in each bolt independent upon plate properties and bolts arrangements. Strength prediction were taken place by 3-D Extended Finite Element Method (XFEM) framework of various staggered and non-staggered arrangements to include various lay-ups types and plate thickness. The failure loads predictions in each testing series were investigated and then validated against experimental datasets and also compared with previous technique (ESS approach). Crack patterns and failure modes from this approach were consistent with experimental observations, where net-tension failures were observed within all testing series. Less good prediction compared to from ESS technique, partly due to semi-empirical nature in former approach. Nevertheless, reasonable agreement in UBP technique with experimental datasets were obtained (average discrepancy of approximately 20%).

Glass used in building facade presents an aesthetic feature as well as contributes to the structural stiffness of the whole structural system of the building. In this research, the contribution of glass on the stiffness of the cable-net supported glass facade systems was investigated via experiments. Two generic configurations of cable-net system were considered, namely flat and curved cable-net system, both with and without glass panes. Each system was subjected to static load. The results indicated that the introduction of certain level of curvature to the cable net structure has increased the stiffness of the cable net structure by 11.5%. The glass panes made significant contributions to the stiffness of the whole structural system. The glass stiffness contribution for flat cable-net system was high at the early stage of loading (approximately 40%) but reduced when the load was increased. However, the glass stiffness contribution for curved cable-net increased gradually as the load was increased. For both configurations, the glass stiffness contribution remained steady at about 18% of the whole structural stiffness as the cables in the cable-net stiffened up to the maximum load.. Based on the static tests carried out, the pre-stress force in the cables in the cable-net systems can possibly be reduced should the glass be considered in the analysis design of cable-net structure. Moreover, the curved cable-net could be designed to have lower pre-stress force in cables compared to that of flat cable-net to meet the deflection criterion of the cable-net structure.
