N t nly can seismic f rce f single m de between transfer st ries increase with transfer st ries l cated at a higher level, but als seismic shear can increase at the first fl r and ab ve the transfer st ries. Natural vibrati n peri ds and m des f the structure can n t change distinctly. Because seismic f rce between transfer st ries is larger relative t t tal seismic f rce when transfer st ries is l cated at a higher level, max imum increment f seismic f rce may appear near transfer st ries, which can lead structural m ment t increase.
