HOME ABOUT STRUCTURAL FRAMES PRODUCTS RESOURCES CAREER CONTACT US DESIGN OF SWT BEAMS PROJECT DESIGN ASSEMBLY DESIGN OF SWT BEAMS Design of composite beams require advanced calculation methods, made specifically for the element in question. Design of SWT beams considers a large amount of parameters, besides the common moment and shear forces. The final element design is therefore always done by SWT’s engineers. For the early drafting stage, the table below is provided as a reference and help for evaluation of systems. You are of course always welcome to contact us for further help in case of complex cases or if you just want to discuss an idea. NOTES ABOUT THE TABLE The height of the beam is measured from the top of the lower flange to the top of the beam. Beams above 340 mm high can be made in more dimensions than what is shown. Please contact SWT for further help if the given dimensions are not enough The bending stiffness EI is given for evaluation of natural frequency.

After installation you will get a new menu named SWT, under which the products are located. Choose the desired product. After clicking on “SWT-balken”, you will get this icon menu. Choose the desired beam dimension in the left list. The column is pasted as a block into your drawing. After clicking on “SWT-pelare rund” (a circular SWT column), you will get this icon menu. Choose the desired beam dimension in the left list. The column is pasted as a block into your drawing. Feel free to contact us regarding this menu.
