v2.01.105 SDLD105 - Transient response of a mass-spring system to a mono-support earthquake with static correction

Summary

This test case, inspired by test case VPCS SDLD04, consists in calculating the undamped transient response of a free-embedded linear mass-spring system, subjected to an imposed mono-support acceleration.

Its objective is to show the value of static correction, whether it is carried out a priori by adding static modes at the base of dynamic modes, or a posteriori.
