  2. But this method still exists some shortcomings such as : while adopting displacement - control analysis method how to estimate the structural displacement requirement, how to select the horizontal load mode before and after the structure yields, how to considerate the high level mode that have a large effect while it is in the later position, how to considerate the elastic - plastic response spectra correctly. these problems remain to be solved. so this method needs to improved furtherly
