EXPERIMENTAL STUDIES OF ASEISMIC SELF-CONTROL IN TALL CONCRETE BUILDINGS

This paper presents new self-control studies of aseismic control of concrete members and structures in tall buildings. The work is a part of a series of projects undertaken by wore than 10 Phd candidate students in Southeast University. The so called "self-control" implies that no dampers are set in tall buildings. Instead measures are taken to weaken appropriately some sections of members which improve the ductility of the structure without reducing sigrificantly the ultimate bearing capacity and the stiffness in service. Alternatively, measures may also be taken to strengthen some sections which increase the ductility of structure and even enhance the ultimate bearing capacity. Two proposals coming up from the present studies have been put into practice.
