Several Problems in Design of Outerjacketing Frame Structure Working Harmonious with the Original Building/Zhang Haoyu,Zheng Wenzhong(School of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China)
Abstract:For the problem that what principle should be adopted in design of the outerjacketing frame structure working harmonious with the original building, the viewpoint is put forward that different design principles and construction sequences should be adopted according to the quality of the original building and the requirements of the original building's owner. In view of different working conditions of the outerjacketing frame structures, connection construction between the outerjacketing frame structure and the original building is introduced. In consideration of the mechanic behaviors of the outerjacketing frame structures,noteworthy problems during calculating moment distribution at the end of top column and bottom column in frame joint are presented. Seismic response of an example of an outerjacketing structure is analyzed to explain the superiority of th
e outerjacketing frame structure designed to work harmonious with the original
building.
