| Abstract: | The extension-story design of a framed office building is introduced.First the dynamic characteristics of the structure with directive adding stores are analyzed,and what structural members should be reinforced are determined.Weak stiffness,low bearing capacity and detail design problems of the old frame can be found.Second,the design of anti-seismic strengthening is carried out and attention should be paid to coordination with the other departments.Finally,the dynamic characteristics of the designed struct... |
| Keywords: | frame structure extension-story axial compression ratio story drift seismic strengthening |
