摘要

傳統之耐震設計法僅要求建築物在強烈地震下不倒塌，這樣雖然能保障生命安全，但未完整考慮在各種大小不同的地震作用下，建築物應具備之耐震能力、容許損害情形及結構物與非結構物之堪用程度，因此今後的耐震設計趨勢除了保障生命安全外，也因兼顧建築物震後使用功能與震後修復成本。故以結構性能為考量的性能設計法已成為新一代耐震設計之主要研究方向，主要依據建築物使用上的需要、重要性及功能等作出分級，以確保在不同等級的地震作用下，建築物具備應有的耐震水準。
本文是以混合式多層結構為研究案例，並根據FEMA-273所提出的位移係數法，輔以SAP2000程式建立結構物模型，利用數個位移係數代表結構反應特性及地震需求，以求出目標位移，然後利用非線性靜力分析之，得知構材降伏及破壞之先後順序，以瞭解結構耐震能力並以非線性歷時分析加以驗證。最後對需要補強之結構，以位移設計法設計消能減震裝置以使其達到性能目標。

The traditional seismic design of buildings is only demanded by the buildings without collapse under serious earthquakes. This may assure the life safety, however the seismic capacity, damage permission and usability after earthquakes for the various kinds of earthquake levels of structures were not considered. Recently, the performance-based seismic design and assessment are becoming a new tendency toward seismic design. It is according to the demand, importance and function, etc on the usage of the building, and definition of the expected behavior of the building in the design earthquake in terms of limiting levels of damage to the structural components. So it can really reflect the actual performance of the buildings.
In the thesis, we investigate the behaviors of the Hybrid Multi-story structure buildings. The framework is based on displacement-modulus method for FEMA273, and the software SAP2000 is adopted to the process of non-linear static analysis. We can obtain the results of structural plastic hinge locations, the interstory drifts and the damage of members at the target displacement, and then check if they satisfy the performance level or not. In additional, nonlinear time-history analysis is carried out and to provide the displacement- modulus method for FEMA273. Finally, when the building is estimated that strengthening is necessary, we use Displacement-Based Design for Buildings with Energy Dissipation Systems in the researches and expected that satisfy the performance level.
