Practical Steps for Seismic Design of Buildings with Supplemental Viscous Dampers

11:32, based on what calculation u entered effective stiffness as 0.1 kN/mm ??

[@irandamp6509]

Almost always you can define zero effective stiffness for viscous dampers. Some engineers prefer define a very small value instead zero (0.1 kN/mm in this example) to account for limited compressibility of the fluid and other connection elements. There would be no difference in the results. So you can use either zero or a very small value as the effective stiffness of viscous dampers. Note that effective stiffness and effective damping are used only for linear analysis.

Thank you, I have visited the website, but I did not find the technical documentations or a written design procedure

Two design procedures are explained in this video. Further written contents can be found at our website TECHNICAL POSTS page. Use this link , irandamp.com/technical-posts/
