JSP has recently installed Corrugated (Sinusoidal) Web Beam technology from Zeman Austria at our Angul Plant, marking a pivotal step towards enhancing the efficiency, performance, and durability of our structural members. This cutting-edge technology is poised to revolutionize how we assess and manage steel structures, offering a multitude of benefits to Pre-engineered buildings/Sheds/warehouses.
The Corrugated Web Beam represents a breakthrough in structural engineering. Comprising wide plate flanges welded to a corrugated web, this built-up girder exhibits remarkable strength and stability. The innovative design allows for flexibility in flange width (ranging from 120 mm to 450 mm) and web depth (from 333 mm to 1500 mm), accommodating diverse structural framing requirements. Notably, the corrugation of the web significantly enhances its stability against buckling, resulting in substantial savings in structural steel usage (approximately 10-30%). This not only improves the competitiveness of our steel buildings but also promotes sustainable construction practices.
The implementation of corrugated web girders results in significant material savings by reducing the need for web stiffeners. This is primarily attributed to the utilization of corrugated sheets for the web, which enhances its buckling strength. Furthermore, the adoption of thinner webs further contributes to the cost-effectiveness of the structure. The design methodology ensures adequate safety margins, enhancing structural reliability.
Advantages and Characteristics of Corrugated Beam:
- Weight reduction and savings
- Significant cost savings
- Reduced roof dead loads
- Prevention of web buckling failure through corrugation
- Lower weight
- Versatile architectural capabilities
- Variable height beams for optimal utilization of sinusoidal beam strength
Application of Corrugated Web Beam:
Corrugated web I-beams have been successfully manufactured and utilized in various countries including Sweden, France, Germany, and Japan. In France, they are employed in composite girder bridges featuring concrete flanges and corrugated steel webs. Recently, Austria has also adopted and incorporated such beams in construction projects. Notably, large span structures designed by Zeman and Co. showcase the efficacy and versatility of corrugated web beams in practical applications. Considering these advancements, we encourage all teams involved in sheds, warehouses, and pre-engineered buildings projects to explore the incorporation of Corrugated Beam Technology.
