Steel.

When we first think about steel, the words that come to mind are, 

Strong, flexible, parametric, support, reliable, an expression of the colour red? 

 

Much like a character from The Incredibles, 

Elastic girl maybe? 

 

The first class started with a story-telling presentation, mapping out the evolution of steel. A journey from a metal to a building material, over different time periods from prehistoric period, a time before written records, with Bronze Age, Stone Age and Iron Age, to modern day where steel, concrete and glass are primarily used in the construction of different structures after the industrial revolution spiking a mass production of these materials.

 

Over a general classification of metals, Aluminium, copper, lead, brass were specified under non-ferrous metals (metals which do not have iron as a component in their chemical composition) while wrought iron, cast iron, steel, stainless steels were specified under ferrous metals (metals having iron in their chemical composition). Steel undergoes a lot of processes to have different properties and material uses. The different processes include, Casting, Drawing, Extruding, Rolling and Forging.  

 

Steel has evolved from just a basic metal used in the old ages as a weapon for survival to a structural material ( AESS – Architecturally Exposed Structural Steel) in the present age. 

 

This theoretical subject was taken in a fun and interactive approach, with exciting activities in the books, like making a spin wheel using household materials. 

 

Looking forward to more flexible, collective learning sessions!

Steel Erection, Fabrication and Hybrid construction -Blog 16

Image
This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very...

BLOG-16 FABRICATION, ERECTION AND HYBRID STRUCTURES

Image
  FABRICATION: The process of  steel fabrication  involves grinding, welding, cutting, bending, drilling, punching, burning or melting and other general crafting methods using various high-quality tools and CNC equipment. ERECTION LIFTING, POSITIONING AND PLACING OF STEEL MEMBERS IN A STRUCTURE  Once the member(s) are lifted and placed in the required place, with the help of temporary supports and equipment, they are fastened and fixed, depending on the nature of connection.  Erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes. HYBRID STRUCTURES Hybrid structures are structures built with composite materials a combination of different materials with steel. A common  hybrid system  consists of hollow core slabs together with steel or cast-in-situ concrete frames                       EXAMPLE STEEL WITH TIMBER     I...

BLOG- 8                                     STEEL , ALLOYS AND THEIR COMPARISON                                                               STEEL AND ALLOYS                                               An alloy is a blend consisting of metal and other elements. Alloys are generally made for achieving properties like greater strength or resistance to corrosion. Steel is an alloy of iron. It mainly consists of iron with some small amounts of carbon. Definition ALLOY :      A homogeneous mixture of a metal with other types of elements                       ...
