SAP 2000

SAP 2000 Non-linear
Useful for computer modeling and design of reinforced concrete and steel structures and design of systems that use fluid viscous dampers.

SAP 2000 Example

In a Recent Design of a Seismic Retrofit we used Fluid Viscous Dampers to reduce the response of an existing concrete parking structure to seismic forces. The computer model shows the seismic response under the El Centro Earthquake of 1964 for (1) bay of the parking structure that is retrofit with Fluid Viscous Dampers.
