How to use Large Mass Method for Seismic Analysis in ABAQUS CAE?

01 December 2022 0 5K Report

I want to perform Direct Integration dynamic implicit analysis on structure using Large Mass method. As my structure is rested on Spring/Connector elements. Now i want to connect the 2nd node of spring with large mass and then apply the Earthquake wave to large mass rather than structure node.

See the description in picture.

Please help..
