本研究乃探討低降伏鋼板剪力牆之結構行為,進行系列之分析與實驗工作探討此系統之勁度、強度、變形能力與消能能力。首先研究此類剪力鋼板之基本剪力挫屈行為,其實驗結果與分析值甚為吻合。其次採用H型鋼作為剪力鋼板之邊界構材,並探討其梁柱接合採彎矩接合與剪力接合之差異,發現所有試體皆具有甚為優異之耐震消能能力。再則探討此類系統在多層構架中之耐震行為,並證實此系統不論採彎矩接合或剪力接合皆可達到6%以上之樓層側位角且仍可保持穩定狀態,本研究又以帶狀二力帶狀桿分析模型進行試體結構之彈性與非彈性分析,其結果亦與實驗甚為吻合。最後再經由比較不同結構系統之彈性與非彈性結構行為,以探討低降伏鋼板剪力牆整體結構系統設計之應用。依據本文之研究結果,提出此低降伏強度鋼鋼板剪力牆系統之設計方法建議。
This research is aimed at studying the structural behavior of low yielding point (LYP) steel shear wall system. A series of analytical and experimental studies were carried out to examine the stiffness, strength, deformation, and energy dissipation of the LYP steel shear wall system. The first series of study is to examine the shear buckling of the LYP steel shear panels. The experimental results agree with that from analytical study very well. The second series of experimental work is to study the behavior of the LYP steel shear wall with H-beams and H-columns as its boundary elements. Both moment connections and shear connections were studied. Good energy dissipation capacities were obtained for all specimens. The third part of this study is the seismic behavior of multi-story shear wall system. Excellent deformation capacities were obtained from both rigid frame-shear wall system and simple frame-shear wall system. The story drift angle can be as high as 6% and still maintains stable characteristics. A two-force strip model was also proposed to simulate the LYP shear wall for the elastic and inelastic behavior. Good correlations were found between experimental and analytical studies. Furthermore, applications of LYP shear wall system in the building design were examined by comparing the elastic and inelastic behavior of different structural systems. Based on these research findings, guild lines for the design of LYP steel shear wall systems were proposed.
