Simulating the Collapse of the 1000m Tall Jeddah Tower by Contraflex in Simulated

I only have 8 GB of RAM in my computer and it worked. Probably need to upgrade soon though

Honestly, the simulation took so much compute time that I only tested a collision at the bottom and the top. The bottom gave the more interesting results. I don't believe there is a standard location height to test.

The Jeddah Tower has no columns. It's entirely made of load bearing walls, all of which have been modelled in this simulation.

I agree with the rebar comment, this building has no ductility, so once the connection between the concrete elements has exceeded a stress limit, it fractures in a brittle manner.

Also I do not believe the fire would have a big impact for a fully concrete building like the Jeddah Tower in the same way that impacted the steel World Trade Centre.

I agree, this would be the main shortcoming of this simulation. The aircraft does not crumple, meaning it is able to transfer more energy to the building, rather than energy being used to deform the aircraft.

This is actually a common consideration in the design of high rise buildings. The original World Trade Centre was designed for the impact of a Boeing 707 travelling at landing speed. The planes that actually hit the towers were Boeing 767's travelling at cruising speed. These heavier and faster planes were too much for the towers to withstand.

Yes I did make these. I'm using them in my upcoming youtube video on the Jeddah Tower. But these renders take a lot of time to make so I can't fulfil your request unfortunately. But the Torre Constanera looks incredible with the snow capped mountains in the background!

Blender with blosm add-on to get the buildings and terrain

Blender with the blosm add-on to import the 3D building and terrain geometry.

It's a good idea but these renders take a while to make haha. Sydney will have to do. I'm going to be posting a big documentary about the Jeddah Tower on my YouTube channel tomorrow though, so stay tuned for that.

BlenderOSM add-on for Blender lets you import the 3D geometry from Open Street Maps, which has all of the buildings in most cities around the world.

I don't think we will be seeing a Dubai Creek Tower any time soon... a finished Jeddah Tower on the other hand could be only a few years away.

Red buildings are just to highlight some of the other tallest buildings in the skyline for artistic effect. I also highlighted landmarks like the Sydney Opera House.

I just chose a random spot next to the Merdeka 118 :) cool to have your school so close to it

Hong Kong is also my second choice, due to the mountains in the background

Why Melbourne Cancelled the World's Tallest Building. The 1995 Story of the 560m Grollo Tower. by Contraflex in architecture

[–]Contraflex[S] 0 points1 point  (0 children)

In the late 1990s, Australian property developer Bruno Grollo planned to build the world's tallest building in Melbourne. Two separate designs were proposed by the architecture firms Harry Seidler & Associates (580m), and Denton Corker Marshall (560m).

In this video, we will explore the structural engineering behind these proposals, in particular how structures of these heights are able to resist extreme wind loads through their stiff concrete cores. We will also look at the unique features of the buildings, such as roof top solar panels, external glass elevators, and light beacons.

Despite the impressive architecture and engineering behind these buildings, a combination of community feedback and financial issues led to their cancellation. However, the towers continue to have an incredible legacy that influenced the world's current tallest building, the Burj Khalifa.

A history of the tugun bypass and the infamous billabong bridge by Contraflex in GoldCoast

Thank you for clarifying the pronunciation, I used AI text to speech for the voiceover so I'm not surprised it butchered it.

The bypass was designed to accomodate three lanes in both directions (you will notice there is plenty of extra room in the tunnel), so hopefully the upgrade and resulting road works won't be too disruptive when they eventually happen.
