Master slave is a substitute for diaphragm at floor level. As the analysis of plate takes too much time and the model becomes complicated, no body prefers to go in for plate. Plate analysis requires too much space on the drive. Difference in result obtained from the two methods is not even 1% which is negligible in case of structural design.</p><div style="clear:both;"></div>
