This paper shows a method of converting a multi-story building into the equivalent single degree of freedom (SDOF) system, which can be applied to performance-based seismic evaluation methods such as the Capacity Spectrum Method. The feature of the converting method is to use information obtained from non-linear push-over analysis. The validity and applicable scope of the converting method were examined through the earthquake response analyses for several regular and irregular shaped buildings in which the responses of the equivalent SDOF system and the multi degree of freedom system were compared. The analytical results showed that the earthquake responses of not only regular shaped buildings but also irregular ones can be predicted by using SDOF system converted by the proposed method. For relatively high-rise buildings, however, the higher mode effect should appropriately be considered to the response of SDOF system.

本論文は、中高層SRC造集合住宅の桁行方向の第2次診断法に基づく建物高さ方向の耐震性能の分布を分析し、強度が低い弱点層に損傷が集中する可能性を示す。特定層への損傷集中に影響する要因として、柱梁耐力比、高さ方向の鉛直部材の強度分布を取り上げ損傷集中との関係を検討する。その結果を踏まえ、中高層SRC造建築物において、特定層への大破あるいは中破以上の大きな被害集中を回避することを目的とし、実務的に使いやすい第2次診断法に柱梁耐力比と高さ方向の鉛直部材の強度分布(第2次診断法の<i>C_TU·S_D</i>の分布)を考慮した耐震診断法(第2、3次診断法)の選定について提案する。

In order to reduce further destruction of buildings and to reduce the number of homeless people caused by the aftershocks, a quick inspection of the damaged buildings ought to be carried out. This research aims at developing an integration method by computing the response displacement from the measured acceleration. This new method provides an automatic and a quick inspection system performed by few cheap accelerometers. The errors included in the measured acceleration data can be accumulated during the double integral. The new integral method, which is based on Iwan's method and a band-pass-filter, is proposed in this paper.
