Lesson-4

This m.file is intended to perform the numerical integration of a structural system subjected to an external dynamic excitation. The integration scheme utilized for this analysis is the newmark-wilson alpha-beta-theta method(collocation method). the collocation method is an implicit time steping scheme so stability of the system need not be considered.
