| Abstract: | Based on analyzing two example structures, a new concept that the same vibrational mode has two mode shapes in two-tower structure or two-tower structure linked by spatial corridors, both with enlarged base, is presented. The principle of choosing vibrational mode numbers in aseismic analysis for this type of highrise building structures is discussed. Their calculating results are compared, and some questions in aseismic design are emphasised. In the end, the useful results for structural aseismic design are given. |
