Abstract
Cable-net supported glass facade is a kind of structure consists of many advantages such as attractive in apparent, constructible and pleasing aesthetics. This kind of structure is commonly used in airport passenger terminals, exhibition centre and hotel hall. In this research, the static performance of the single layer cable-net structure with and without glass panels was investigated through the experiment. The influence of potential damages on its static behaviour of single-layer cable-net structure were also investigated in this study. Three types of damage were considered in this research which are failure of cable connector that is between two spanning cables, loss of pre-stress in cable and cable anchorage failure. The results also indicated the glass stiffness contribution of the whole structural system. The experimental results show that the failure in cable connector has little influence on the static performance of single layer cable-net. The maximum change in nodal displacement and cable tensile force are 2.78% and 1.65% for both cable-net with and without glass panels. Furthermore, the cable anchorage failure affects significantly the local part of the structure induced by the changes in nodal displacement up to 16% and 19% of the cable-net with and without glass panels, respectively. In contrary, for the pre-stress loss occurred in horizontal cables, the percentage of change in nodal displacement is lower (3.23%) as compared to the pre-stress loss occurred in both directions where the change in nodal displacement is up to 32.52% for the pre-stress loss occurred in both directions of the cables. The maximum values change in cable forces was not exceeding 13.64% for all cables under the pre-stress loss and cable anchorage failure. From the results, it can be concluded that the influence of damages was stronger for the on nodal displacements than cables tension force. Other than that, the intensity of the influence damage depends on the location and the extent of damage. The near the position of node to the damage, the higher the nodal displacement. However, the percentage of the nodal displacement is lower for the cable-net with glass panels compared to cable-net systems without glass panels. The effect of the glass stiffer the cable-net structure. The stiffness contribution of the glass is between 21% to 25.04%, 14.33% to 21.10% and 7% to 21.1% for the respective pre-stress force of 2000 N and 1000 N, 1500 N.
