But the authors focused on the effect of the damages on the structural displacement and the cable tension force, but the glass panel could break if its stiffness contribution is too large.
Abstract: The single-layer cable net supported glass curtain wall has been applied in many building structures all over the world. In service, it will inevitably be subject to various damages. To study the influence of such damages on the static behavior of the single-layer cable net supported glass curtain wall, a full-scale model with the outside outline size of 4.85 m × 4.85 m and 4 × 4 grids is designed and tested. Two kinds of damages that are the cable prestress loss and cable anchorage end failure are led into the structure model during the test, and their influence has been investigated. The stiffness contribution of glass panels to the single-layer cable net supported glass curtain wall structure with or without damages and its change have been tested and analyzed. The results show that the maximum change rate of nodal deflection is 13.78% for the damage of cable prestress loss, while the change rate of nodal deflection is between 7% and 22% for the damage of cable anchorage end failure. The influence degree of the damages depends on the ratio of the structure initial stress stiffness change caused by damages to the total stiffness of the structure. The stiffness contribution of glass panels increases with the load increase. Under the same loading condition, the stiffness contribution of glass panels to the damaged structure is greater than that to the intact structure. The stiffness contribution of glass panels reduces the effect of the damages on the structural displacement and the cable tension force, but the glass panel could break if its stiffness contribution is too large.

TL;DR: In this paper, a building exterior wall external heat insulating composite curtain wall plate is proposed, which is fine in fire proof property, is stable, weather resistant and corrosion resistant, avoids high fire safety hidden dangers or fatigue cracks, prolongs service life and keeps heat insulation effect for a long time.
Abstract: The utility model discloses a building exterior wall external heat insulating composite curtain wall plate, which comprises a heat insulating layer and a decorative layer. The heat insulating layer and the decorative layer are sequentially fixed on the building exterior wall from inside to outside, the heat insulating layer consists of a heat insulating plate and a base plate which are integrated, the heat insulating plate comprises a fire-retardant inorganic heat insulating material body and a plate frame fixedly arranged on the periphery of the fire-retardant inorganic heat insulating material body, the base plate and the heat insulating plate are fixedly arranged on the building exterior wall via fasteners, and the decorative layer is bonded onto the outer surface of the base plate via an adhesive layer. The building exterior wall external heat insulating composite curtain wall plate is fine in fire proof property, is stable, weather resistant and corrosion resistant, avoids high fire safety hidden dangers or fatigue cracks, prolongs service life and keeps heat insulation effect for a long time. During usage, the decorative layer can not be cracked, the composite curtain wall plate is light in weight, eliminates safety hidden dangers after high-strength anchoring, saves mounting cost as a keel structure is removed, and is short in mounting and constructing period and low in construction difficulty, thereby increasing working efficiency.
