Prediction of Deformation Demand on Frame Buildings With Histeretic Dampers


Abstract eng:
This study focuses on framed buildings equipped with hysteretic dampers, and introduces a methodology to estimate the seismic deformation demand after damper installation. The proposed methodology considers not only structural and dynamic characteristics of the main frame and dampers, but also input ground motion characteristics. For this purpose, five building structures with 2, 4, 6, 8 and 10 stories were designed according to the Colombian code, and further converted into equivalent single-degree-of-freedom (SDOF) system models. Hysteretic dampers with varying mechanical properties were then installed into the SDOF models. The SDOF models were subjected to a series of 30 input ground motions, which were modified to represent the seismic intensity given in the Colombian code and to grant certain control over the input energy. Nonlinear dynamic analyses were carried out, where parameters such as deformation, acceleration, input energy and hysteretic energy were investigated. The predicted deformation demand obtained from the proposed methodology was compared with that obtained from the analyses. The methodology was shown to be useful for the preliminary assessment of the seismic performance of framed buildings with dampers.
