초록

In 2000, Standard Design Loads for Building was changed especially in seismic load. According to the change, seismic-resisting capacity of deteriorated apartment houses has to be reestimated. This research is to propose seismic-strengthening and improving methods of structural efficiency of RC deteriorated apartment houses. The analysis models were shear-wall system(36/58/79$m^{2}$) and beam-column system(11/19/25py) which were constructed in early 1980 and didn't consider seismic load. The definite methods are addition of shear walls and lightening of load. The story-drifts of shear wall systems exceed allowable story-drifts so that two methods was applied. The story-drifts of beam-columns system satisfy allowable story-drifts, thus the latter is applied. The seismic-resisting capacity of these systems was improved by the two methods. This research will be helpful to remodel deteriorated apartment houses.
