In this work, a transient response reanalysis technique is developed and programmed. The developed method comprises the local modification technique for eigensolution reanalysis and the mode superposition technique for transient response reanalysis.
This developed technique enables us to calculate the transient response of a locally modified structure economically. Successive and reversible modifications are allowed and this method can be used to derive an optimal design of a system having many constraints both in responses and in design parameters.
The programmed software is verified by comparing the results of several example problems with those of the whole modified system using DVERK, IMSL direct integration routine. The comparisons showed that the developed software give correct results up to the three digits under the decimal point.
