Facades installation technological solutions of Maxima shopping center

Today’s commercial building facades provide the first opportunity for the building to capitalize on the natural environment and minimize thermal and lighting loads.
The point fixed glass facade system is popular and considered a more elegant facade option compared to the framed glass facade system mainly for storefront, walkways and lobby areas in buildings. Point fixed glass facade system is fixed to the support structure using special bolt fittings and structural spider arms.
Generally, the racking performance of these systems is not considered at the design stage in low to moderate seismic region and the system may be vulnerable if there is insufficient in-plane drift capacity compared with the demand imposed during earthquakes and wind actions. A unique full-scale in-plane racking laboratory test on a typical point fixed glass facade system was conducted and a maximum drift of 2.1% was measured before catastrophic failure. Non-linear finite element models were then developed and benchmarked against experimental results.
The experimental results and finite element analyses indicated that a significant amount of the drift capacity was attributed to the rigid body translation in the facade system connections at the built-in oversize holes provided for construction tolerances.
Though glass will always impact the HVAC performance, a facade that is well integrated into the architecture and building systems can have a net positive impact on the total energy performance and is the first step to achieving what is considered a high-performance building.
In practice, the PFGF systems have some variation in terms of glass panel shapes, glass thickness, sealant thickness, sealant types and facade grid arrangements, and therefore, the racking performance of other in-situ systems could be quantified using a predictive analytical model such as finite element (FE) modelling.
Therefore, a non-linear FE model was developed and conservatively benchmarked against the laboratory test results to enable the performance of other PFGF...
