HSBC Hong Kong | sistema estructural suspendido

Summary

The HSBC building in Hong Kong, designed by Norman Foster, features an innovative suspended structural system. This system transfers vertical loads through steel masts and cables, allowing for expansive, column-free spaces inside. With eight tubular steel masts and a central core, the building can withstand both vertical and horizontal forces, such as wind. The design, completed in 1986, exemplifies modernist hi-tech architecture and sets a new standard for skyscraper engineering, allowing for large spans while maintaining stability. The use of a physical model helps to visualize the load distribution across the structure.

Takeaways

• 😀 The suspended structural system transmits vertical forces upwards to a core, which then transfers them to the ground.
• 😀 A notable example of this system is the HSBC Building in Hong Kong, designed by architect Norman Foster.
• 😀 The HSBC Building has 47 floors, stands at 180 meters tall, and was completed in 1986.
• 😀 The building features eight masts that act as modern equivalents of columns, each made of four tubular steel columns.
• 😀 The design of the building allows for large spans without the need for conventional columns, similar to a cable-stayed bridge.
• 😀 The space between the masts in the HSBC Building is about 200 meters, allowing for an expansive interior design.
• 😀 The structural system consists of a combination of a truss, slabs, masts, and suspenders (also known as 'hangers').
• 😀 The masts are connected with steel, which helps to rigidify the structure and combat vertical forces like wind.
• 😀 The structural forces are transferred from the suspended elements to the upper trusses and then to the central core.
• 😀 The building’s facade features additional metallic trusses that resist horizontal forces, ensuring stability against lateral movement.

Q & A

What is the basic concept of the suspended structural system described in the video?

The suspended structural system is one where vertical forces are transmitted upwards to a central core, and this core then transfers the forces down to the ground. It allows for large open spaces without the need for traditional column grids.

Can you explain the role of the mast structures in the HSBC building?

The HSBC building uses eight mast structures, which act as new columns. Each mast is composed of four tubular steel columns. These masts help transmit vertical forces and provide the necessary support for the building's large spans, allowing for expansive open spaces inside the building.

How does the structural system in the HSBC building allow for large open spaces?

By using a suspended system with masts and steel cables, the building avoids the need for conventional vertical columns, creating vast spans of space, as seen in the building's floor plan. This reduces the need for a conventional column grid and maximizes the available floor area.

What is the purpose of the armatures in the building’s structure?

The armatures in the building's structure serve two main purposes: transmitting vertical forces upwards to the core and resisting horizontal forces, such as winds. These armatures are key to maintaining the stability and load-bearing capacity of the building.

How are vertical forces managed in the structural system?

Vertical forces are transmitted through steel cables and the armature structure, which directs these forces to the central core. The core, represented by the four tubular columns, then transfers the forces to the ground.

What is the significance of the term 'percha' in the context of the structural system?

'Percha' refers to the structural element that connects the masts with the armature. In English, it is often translated as 'hanger' or 'hook,' indicating its role in suspending and transferring forces.

How does the steel system in the building resist horizontal forces?

The steel system, including the armatures and the connections between the masts and core, helps resist horizontal forces, such as wind. These components work together to stabilize the structure against lateral forces.

What is the purpose of the physical model shown in the video?

The physical model serves to visually represent the suspended structural system. It demonstrates how forces are transmitted through the structure, with elements like the metal rule symbolizing the floor slabs and the red thread representing the 'perchas.'

Who was the architect of the HSBC building, and when was it completed?

The architect of the HSBC building in Hong Kong was Norman Foster. The building was completed in 1986 and is an example of high-tech modernist architecture.

What are the dimensions and key features of the HSBC building?

The HSBC building is 180 meters tall and has 47 floors. It is a modernist, high-tech design, incorporating innovative structural elements such as the suspended system with masts, which allow for large, open spaces within the building.
