  AESS CUSTOM CATEGORY AESS Custom category   allows flexibility in the design of steel. It also requires a high level of communication. The premium ranges from 20% to 250% over regular steel. These type of custom elements was created so that there’s an allowance of a custom selection for the attributes or characteristics that are used to define other categories. Reused steel is also included for sustainable purposes. EXAMPLE 1 : HEATHROW TERMINAL 5 Located in London’s main airport. Architect’s: Richard Rogers Partnership, Pascall + Watson. Engineers: Arup and Mott MacDonald. Construction and integration of 18,000t complex plan spanning roof seemed to be the challenge. The massive steel arches, weighed a combined   2,100t and were bolted into position. This project in England has made use of a range of AESS category types. The connections are made using a combination of custom work for the central hinge, and showcase level of fabrication and fini...

  AESS - Architecturally exposed steel certainly differs from standard structural steel. AESS is divided into five categories based on various factors. Steel members of similar qualities are also categorised under different AESS, due to the nature, scale of the project or even where the steel member is used.  Such a category is AESS 4, which is labelled for steel members employed as showcase members in a structure or a building. The factors to be considered to identify the level of AESS for a project are      •       Member Visibility As the name says, the visibility of the steel member lays the conditions for the finishes and detailing. The design time and efforts are put for the member/ part of the member that is visible or exposed for the view. Identifying such specific locations will take analysis and careful consideration. In AESS 4 the weld seams must no longer be visible. •         Viewing Distance Any object 20ft f...

  01/September/2020 Today’s session is clearly a continuation of my previous blog. Sections were already a part of the evolution and today's session made it clear that certain things, even though evoloving, does not lose its originality and they do have their own importance because of which it becomes irreplacable. So, today was about learning the different types of sections available in standard structural steel and about a more complex steel strata called AESS. The details are as follows :-   Market forms of steel Angle sections - Equal and unequal angles of sizes (200x200x25) mm - 736N/m length, 30x20x3mm -11N per m length. Usage - Filler joist flooring, structural steel roof trusses, bridges, etc Channel sections - 2 flanges and 1 web section, Types - ISJC (Jr.), ISLC (Light), ISMC (Medium) and of sizes 100x45 per metre length - 58N Corrugated - Formed by passing steel sheets through grooves and its market form is GI sheets - used as roof covering material Expande...
