Seismic Evaluation of Retrofitted Factory with Rubber Bearing and Design Method

Abstract:

For particular change of function, factories are sometimes to be retrofitted into specific buildings with insertion of additional floors. Conventionally, there are two methods in retrofit of factories when additional floor is needed. One is the reconstruction of a secondary structure inside the existing building, while the other is the so called direct construction of additional floor. The latter is preferred on particular occasions due to the simplification of procedure. However, strengthening is still required in this case for the loads induced by extra floor may impose an adverse effect on existing strucutre. In this study, the rubber isolation is introduced into retrofit of factories. Based on case study, its effect in isolating earthquake is evaluated, and relative discussion is also made with energy balance concept. The design procedure of retrofit design of factories with additional floors is discussed in this study, which may provide instruction in applying this technology into engineering practice.
