The main technical requirements include:<\/p>\n<ul>\n<li><strong>Over the Big Span:<\/strong> The roof structure must be able to span the entire span of the skylight without any supporting columns in between, ensuring the space below is completely clear.<\/li>\n<li><strong>Optimizing Natural Light:<\/strong> The main function of a skylight is to provide light. Therefore, the roofing material must have a suitable translucent level so that natural light can diffuse evenly to the lower floors, avoiding darkness and glare.<\/li>\n<li><strong>Ultra-lightweight construction:<\/strong> The new roofing solution must have low self-weight so as not to overload the existing load-bearing structure of the building.<\/li>\n<li><strong>Safety and Acoustics:<\/strong> The roof material must be safer than glass (avoiding the risk of breakage), and must also have sound absorption capabilities to reduce echoes in a large, high space.<\/li>\n<\/ul>\n<h2>Technical Solutions and Implementation Process<\/h2>\n<p>To meet the above requirements, a steel arch structural solution combined with a high performance tensile membrane was selected.<\/p>\n<h3>Barrel Vault Structure Design<\/h3>\n<p>The technical solution chosen was a barrel vault. The roof is made up of a series of curved steel trusses, placed parallel to each other to span the large aperture of the skylight. Tension membrane panels are installed and stretched between these trusses. This design is highly structurally efficient for rectangular spaces and creates a high, airy interior space.<\/p>\n<figure>\n<p>    <img decoding=\"async\" src=\"https:\/\/flexiiform.vn\/wp-content\/uploads\/2020\/09\/CBS_Mai-che-thong-tang-4-1024x683.jpg?v=1630602835\" alt=\"Chi ti\u1ebft k\u1ebft c\u1ea5u gi\u00e0n th\u00e9p c\u1ee7a m\u00e1i che th\u00f4ng t\u1ea7ng.\"><figcaption>The arched steel truss system is designed to span large spans and provide shape for the roof.<\/figcaption><\/figure>\n<h3>High Performance PVDF Stretch Film Material<\/h3>\n<p>The covering material is PVDF (Polyester coated with PVC) stretch film. The PVDF coating provides UV resistance, anti-fouling and long life. The translucency of the material is selected at an optimal level, allowing about 20-40% of natural light to pass through. This creates a diffuse, uniform, glare-free light source, helping to save on lighting costs. The soft surface of the film also has a sound-absorbing effect, significantly reducing echoes in the atrium space.<\/p>\n<h3>Safety and Installation<\/h3>\n<p>Compared to glass roofs, tensile membranes have outstanding safety advantages. In the event of an object impact, the elastic surface of the membrane will withstand better and will not create dangerous fragments. The installation process is carried out using prefabricated components, allowing for quick and safe construction at height.
