Project Overview: Construction of the lobby canopy at Vasidtee Building
Project Covered reception hall at Vasidtee Building is a technical solution to expand the covered area for the lobby and parking area. The project applies a sail-shaped tensile membrane structure with a smart hybrid structural solution, helping to maximize the covered area without using heavy support structures, ensuring ventilation and aesthetics for the facade of the project.
- Investor: Vasidtee Buildings
- Category: Architectural canopy for lobby and drop-off area
- Structure: Sail-shaped membrane (hypar) with steel column and cable support system
- Main materials: PVDF stretch film, steel structure, high strength steel cable
- Location: Bangkok, Thailand (Assumption)
Technical Requirements Analysis & Project Context
The project was implemented with the aim of expanding the coverage of the existing lobby to cover the parking area, improving the convenience for residents and customers. The technical requirements and challenges include:
- Expand coverage area: A canopy solution was needed that extended from the existing lobby to the traffic area to provide cover for vehicles picking up and dropping off guests.
- Avoid heavy textures: The new roofing solution must have an ultra-light structure, avoiding the use of heavy materials such as concrete to avoid overloading the existing structure.
- Maintain a well-ventilated space: Avoid placing support columns in the central area of the lobby and walkways to avoid obstructing visibility and movement.
- Reasonable structural layout: New load-bearing columns must be located in locations that do not affect functionality, such as in adjacent green belts.
Technical Solutions and Implementation Process
To solve the above problems simultaneously, Flexiiform has come up with an innovative technical solution, combining many different load-bearing methods.
Sail Structure Design (Hypar)
The design solution is a sail-shaped tensile membrane (hyperbolic paraboloid – hypar). This form not only brings a modern, elegant architectural beauty but is also highly efficient in terms of structure, allowing the creation of stable surfaces with only corner anchor points, very suitable for the requirement of a compact structure.
Hybrid Structural Solution: Steel Columns and Cables
To meet the requirement for a minimalist structure, a hybrid structural solution was applied:
– Fixed anchor point: One edge of the tensile membrane is anchored directly to the building's existing concrete roof structure, taking advantage of the available load-bearing capacity.
– Steel column: The external anchor points are supported by a system of single steel columns, cleverly arranged within the green belt so as not to obstruct the walkway.
– Central tension point by cable: To create a high point in the middle of the lobby and avoid having to place a column in the center, a cable suspension system was used. A point on the membrane is pulled up by a tension cable, anchored to the building facade on the upper floor. This technical solution both shapes the roof and ensures that the view from the lobby to the outside is completely unobstructed.
Sustainable Engineering Materials
Using high-grade PVDF membrane material, which is UV resistant and self-cleaning. The steel structure and cables are treated with anti-corrosion to ensure long life in outdoor environments. This is the optimal material solution for projects. architectural stretch canvas.
Results and Performance Evaluation
Project Covered reception hall at Vasidtee Building successfully addressed the design challenges, delivering an efficient and innovative solution:
- About function: Successfully expanded the covered area, protecting the entire lobby and parking area from sun and rain, significantly improving comfort.
- Technically: Hybrid structural solutions have proven to be highly effective in creating a lightweight, stable structure without the need for complex column support systems.
- Aesthetically: The canopy with elegant sail shape has become a modern architectural highlight, enhancing the value and elegance of the building facade.
- On space efficiency: Removing the central support column has maintained a spacious, airy lobby space, meeting the investor's requirements.
