Abstract
The paper discusses the design, fabrication and the execution of the cladding supported by steel trusses and curtain wall of a sports club. The cladding and the curtain walls were subjected to a wind load of 1.2 Kpa considering basic wind speed of 25 m/s as per the project specifications. The first part of the paper deals with the cladding work of the canopy that consist of a 4 mm thick aluminium composite panels supported by steel trusses extended from the main structure. Two types of steel trusses were provided, the main truss connected to the space truss, whereas the intermediate truss connected to channels. Both trusses were spaced at 2.5 m centre to centre. These trusses were fabricated at factory and transported to the site for installation. The second part of the paper is related to the curtain wall design having Maximum Mullion spacing of 2 m, considered as worst scenario for the design calculations. The maximum Mullion height was 5.55 m, adopted in the calculations with bottom and top pinned connection. The Technal system was adopted for the design of mullions and transoms. Design was carried out using numerical modeling with CSI SAP2000 for cladding and its supporting structures. The bracket was realized and checked for the corresponding induced forces. All the structural systems were found safe according to different acceptance criterion.
Highlights
IntroductionThe curtain wall façade carried its own weight in addition to the external loads acting on it
This concludes that the cladding panels are safe to winstand the desing ultimate loading under the wind load combinations
The cladding panels are safe for both ultimate limit states and serviceability limit states
Summary
The curtain wall façade carried its own weight in addition to the external loads acting on it These loads are transferred to the main structure. In the mid of 19th century Glass curtain wall started to be used as non-load bearing structure due to the development and widespread use of steel and later reinforced concrete. Later at 20th century, it tended to be unique and custom-made, fabricated individually from the cast iron, rolled steel and plate glass that just began to appear as industrialized production. This gave way to increased use of glass as an exterior façade, and the modern day curtain wall was born [1] [2]. Views after renovation and during execution work for the sports club are shown in Figure 1 and Figure 2
