Abstract
The control method of failuremode of tall steel frame buildings by strengthening structuralweak stories is mainly studied in the paper. Firstly, the structural non linear calculation model and the criterion of failuremode are given. Secondly, based on the concept of uniform damage, the damage model and structural columns sections. changing situations are given. Finally, the weak stories strengthening criterion of the w eakest failure mode of tall steel fram e buildings is mainly studied. Theweakest failuremode can be controlled by strengthening the w eak stories o f the weakest failure mode. The seismic failure mode controlmethod of tall steel frame buildings in the paper is verified by an example. The research in the paper shows that tall steel frame buildings. seism ic failuremode can be controlled effectively by strengthening theweak stories in the weakest failure mode.
