| Abstract: | With the construction of more and more super high buildings and large scale flexible structures, great attention has been paid to information about long period response spectrum exceeding 4～6s, which is the basis of anti seismic design of large scale flexible structure. However, most of current anti seismic codes, such as the anti seismic design codes for highway construction used for the basis of large highway bridge design, are inadaptable just due to shortage of available information of the spectrum note |
