Pictorial Expression and Radiance of Steel Frames, The Crystal Palace

~Steel Frame Structures, Expression of Design/Decoration, and Prefabrication~

What steel frame structures have brought to the field of architecture includes not only improvements in structural performance, constructability, workability, and reliability, but also their delicate expressive power.
Beyond the linear, drawing-like expression when used alone, the range of expression and appearance expands significantly when combined with other members.

The Crystal Palace was selected from a public design competition for the World's Fair, with Joseph Paxton's iron and glass proposal being chosen.
It is said that he was inspired by the radial and intersecting patterns of water lily leaf veins.
It covered a total area of 80,000 square meters and was completed in 1851, six months after construction began.
The Crystal Palace that was actually built differs from Paxton's original proposal.
This was because three elm trees were not cut down, and a circular roof was created to enclose the giant trees.

This Crystal Palace utilized comprehensive technologies that can be called the origin of today's construction techniques, such as thorough standardization of members, ingenious details, truss framing, curtain walls, indoor environment control, and quality management.
It is something that leads to the so-called prefabrication construction system.

After the World's Fair ended, it was relocated to the suburbs of London, but in 1936, the iron and glass melted due to a fire, and the Crystal Palace disappeared.

Today, buildings called Crystal Palaces exist all over the world.
You can see the radiance of crystal and the delicate and elegant expression of steel frames.
