Seismic Analysis Of A High-rise Building Of Short-pier Shear Wall Structure With High Transfer Floor

In this paper, based on the state of the art of researches and applications about High-rise Building of Short-pier Shear Wall Structure with High Transfer Floor, the dynamic characteristics and stress performance of Guangzhou Runhui Tower which is such a typical complicated high-rise building are analyzed by using large finite element program ANSYS. Furthermore, the influence of transfer story which is arranged vertically at different level on global dynamic properties of the structure and on local stress performance of the transition beam is studied. The primary contents of this paper are as follows:First, the static analysis is conducted to gain the force and deformation of the structure, taking the combination of gravity, live load and wind load into account.Second, dynamic characteristics such as modal frequency and modal shape are obtained in modal response analysis. Studies indicate that the results of the two different structural models in ANSYS and those of ETABS agree approximately well. In addiction, the deformation and stress distribution of transfer floor and its nearby floor are also analyzed.Third, three strong ground motion records (El Centro 1940, Tangshan 1976, Artificial Guangzhou wave) are used for the time-history analysis, the results are compared with those of modal response analysis. In the article, the width of aseismatic sews is also researched.In the end, the influence of transfer story located at the third, the sixth and the ninth floor on deformation of the structure and on stress of the transition beam is studied.Based on the above results, the paper provides some meaningful and valuable suggestions for the analysis and design of the type of structure.
