The Taiwan code is based on the principle that “No collapse in strong earthquake, reparable in normal one, and no damage in weak one.” However, the building is constructed with elastic design and aseismic design. It does not analyze the nonlinear behavior of the structure under earthquake. In order to understand whether the building has sufficient capacity to resist earthquake force after the design is completed, Therefore, a two-stage design method for building structures is proposed. Including elastic design and nonlinear deformation check, nonlinear analysis includes nonlinear pushover analysis and nonlinear dynamic time history analysis.
This study will establish a 30-story reinforced concrete building with this process, with the current design, the details of the nonlinear analysis phase are defined in reference to the Taiwan specification and the US specification, including the method of checking the nonlinear pushover analysis and the operation and checking method of the nonlinear dynamic time history analysis.
The results show that the nonlinear pushover analysis differs from the results of the nonlinear dynamic time history analysis. Therefore, for high-rise buildings, nonlinear dynamic time history analysis must be performed to confirm the building′s response to earthquakes. In addition, the method of nonlinear dynamic diachronic analysis will be proposed to complement the imperfections of Taiwan′s specification. In the aspect of selecting the seismic record, it is recommended to obtain information from the station adjacent to the construction site to ensure that it has the characteristics of the construction site. And the seismic record should be composed of the north-south direction and the east-west direction as the maximum direction seismic record, there are two methods to modified the seismic record, the Scaling method and the Spectral Matching method. The scaling method proposes to use the spectral acceleration value in the range of 0.2T to 1.5T of the seismic response spectrum as the basis for scaling, the average of the maximum-direction spectra for

exceeds 90% of the target spectrum in the range of 0.2T to 1.5T In the study, the analysis result is similar to the matching method with the adjustment factor of 1.1 times and the scaling method with 0.9 times as the adjustment factor. Therefore, it is recommended that the adjustment factor of matching method shall use 1.1
Finally, we will summarize all the analysis results and propose a complete two-stage design method for high-rise buildings. |
