台灣處於歐亞板塊與菲律邊海板塊之間，近年來台灣地震規模較大且較為頻繁，建築型式從中低樓層轉為高樓層，使得結構物的週期提高，因此提高建築物之抗震能力是有其必要性，近幾年建築物的抗震設計多半以耐震為主，隔震建築物在近幾年也持續的蓬勃的發展，且在全世界的應用相當普及。
摩擦型滑動支承在消能源理上是以摩擦力來減少建築物受地震力之影響，因此摩擦行滑動支承以摩擦係數作為主要設計參數，以往在測試其摩擦型滑動支承的性能表現是以振動台來測試。振動台的測試可以得到動摩擦係數的變化，手動油壓千斤頂可以靜力側推來得到最大靜摩擦力，但尚未以真實地震來測試摩擦型滑動支承的性能表現。
本文研究對象為成功大學歸仁校區複合性災害實驗平台。在過去的研究中，皆以實驗的方式來識別平台現地性能，因此本文將以數值模擬方法來預估平台的行為，並與過去實驗比較是否有差異，此外，由於平台受外在因素影響導致期出現傾斜行為，本文將會以考慮傾斜角度影響，以識別傾斜造成的影響，並提出合理的數值模型來描述隔震平台的運動行為。

Taiwan is located between the Eurasian Plate and the Philippine Sea Plate, and in recent years, the region has experienced increasingly frequent and high-magnitude earthquakes. Along with this, building construction in Taiwan has shifted from low- and mid-rise structures to high-rise buildings, resulting in increased structural periods. Therefore, enhancing the seismic performance of buildings has become a critical necessity. While seismic design in recent years has primarily focused on strengthening (resistance-based design), base-isolated structures have also seen rapid development and are now widely adopted worldwide.
Friction-type sliding bearings dissipate energy through frictional forces to reduce the impact of seismic forces on buildings. The coefficient of friction serves as a key design parameter for these devices. Traditionally, the performance of friction-type sliding bearings has been evaluated through shaking table tests, which can capture variations in dynamic friction coefficients. Manual hydraulic jacks have also been used to measure maximum static friction. However, there have been few evaluations of the performance of such bearings under actual earthquake conditions.
This study focuses on the base-isolated reinforced concrete (RC) platform with a single-story full-scale steel building at the Guiren Campus of National Cheng Kung University. Previous studies have identified the in-situ performance of this platform primarily through experimental methods. In this research, numerical simulations are employed to predict the behavior of the platform and are compared against past experimental results to assess any discrepancies. Additionally, due to external environmental factors, the platform has experienced tilting. Therefore, this study incorporates the effect of tilt angles to assess the influence of this inclination on structural behavior.
