摘要:	抗彎構架（MRF）已被廣泛用作抵抗側力之系統，雖然此系統具有良好的韌性，但因勁度較低導致其受力時會產生過大的變形。為了改善上述抗彎構架之缺點，本研究提出雙面波浪鋼板填充牆構架系統。研究中針對六組構架，包括一組空構架以及五組配置不同彎折角度之波浪鋼板填充牆構架，施以反覆側向力進行試驗，藉此探討單面波浪鋼板填充牆（ST 系列）與雙面波浪鋼板填充牆(DT 系列)之強度、勁度和消能容量，以評估波浪鋼板填充牆之耐震性能。由實驗結果得知，當單面與雙面波浪鋼板填充牆與構架具適當接合時，其耐震行為表現良好。相較於單面波浪鋼板填充牆，雙面波浪鋼板填充牆具有更佳的耐震行為。此外，本研究利用有限元素模擬分析和理論分析所獲得的結果，與試驗結果進行比較，由比較結果得知，本研究所提出之方法具適當正確性，為有效之分析方法。;Moment resisting frames(MRF) have been commonly used as lateral load resisting systems. The MRF systems possess significant ductility, however lower stiffness that usually incur excessive deformation.To improve the performance of MRF, application of inovative double-sided trapezoidal steel plate infill wallwas proposed in this study. A series of experimental and analytical investigations were carried out. Six frame structures, including one bare frame and five frames with various arrangements of corrugated plate infill walls were tested under cyclic load.The strength, stiffness and energy disspation of frames with single-sided (ST Series) and double-sided (DT Series) trapezoidal steel plate infill walls were compared to evaluate the seismic performance of the proposed design. It was found from the test results that both ST and DT specimens exhibited high performance when adequate connections between the plate and surrounding frame members were designed. Further comparisons on the responses of ST and DT specimens indicated that higher performance gains was achieved when double sided trapezoidal plates were used. Finally, the test results were compared with the results obtained from finite element simulation and analytical calculation. Adequate accuracy was achieved which justified the effectiveness of the proposed design method and the analytical model.
