摘　　要：本文介绍东南大学10多名博士研究生对混凝土高层建筑中部件和结构进行的一系列抗震控制试验研究中的一部分内容——自控研究。所谓“自控”即不设置任何阻尼器而采取适当削弱某些截面以达到提高结构延性的目的，但不使极限承载力和使用荷载下的刚度降低过多；或增强某些截面即相对“削弱”另一些截面，以提高结构的延性，乃至提高结构的承载力。这些研究中已有两项在实际工程中得到应用。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.
