Abstract
A half-scale three-story reinforced concrete frame building was shaken to collapse the shaking table in NCREE Tainan Laboratory in Taiwan in August 2017. This building was used as a case study to investigate modeling techniques for near fault effects on building structures, nonlinear structural simulations. The analytical studies suggest that the fiber-model beam-column element considering RC column effects simulates the responses of the three-story building specimen. Moreover, considering the effects of the stiffness reduction of the RC beam and column members can further enhance the accuracy of the response simulations. The RC column model incorporating fiber-beam-column element using the stress-strain relation for monotonic loading of confined and unconfined concrete - proposed by Mander et al. (1988b) in this study can satisfactorily simulate the degrading force versus deformation relationships of the RC column model. A frame model incorporating the same type of fibered column element could predict the key maximum experimental responses of the test building. Based on these nonlinear response analyses, it is illustrated that the responses of the building can be estimated satisfactorily by using the modeling techniques presented in this study. ? NCEE 2018.
