論文題目(中): 具矽酸鈣板外覆材之輕鋼構牆軸向承載能力研究
論文題目(英): The Study of Load-Carrying Capacity of the Steel Wall Frames With Calcium Silicate Board Under Axial Loads
摘要(中):
本研究乃針對輕鋼構牆具矽酸鈣板外覆材,接合螺絲間距與外覆材板材厚度變化,對於破壞模式與破壞強度的影響為主要的研究方向。除此之外,外覆材相關參數亦為本研究重點之一,故本研究對於國內常用於隔間牆所採用矽酸鈣板進行一系列板材的試驗,以求得適合於國內板材的外覆材參數。利用牆體實驗所得相關數據,與AISI規範和AS/NZS規範做一比較,並依本研究所得實驗數據探求適合的有效長度係數(K)與建議公式,以提供相關研究或設計使用。
由實驗結果分析得知,外覆材參數若利用0.6倍最大載重與相對的位移做計算,其外覆材參數介於175.795~268.341 kN,剪應變介於0.0028~0.0052之間。牆體若採用AISI規範預測強度有明顯低估的現象,其冷軋型鋼框架若採用矽酸鈣板為外覆材時,其破壞模式會因外覆材的束制而有所改變,對於改變外覆材厚度與螺絲間距,其破壞強度約為無外覆材框架破壞強度的1.83~2.27倍。
摘要(英):
This study is concentrated on the strengths and behaviors of cold-formed steel wall frames with silicate board. By changing the distance between self-drilling screws and the thickness of sheathings, steel wall frames were tested in this research. In addition, relative parameters were obtained from a series of silicate board tests in order to adopt in the computation of the strengths of wall specimens. The comparisons were made between the tested results and the predicted values calculated based on AISI and AS/NZS specifications. The recommended effective length factor (K) was also proposed for the design purpose.
By using 0.6 times the ultimate strength and its displacement from each individual board test, the sheathing parameter was found between 175.795 and 268.341 kN, and the values of sheathing shear strain varies from 0.0028 to 0.0052. The sheathing material affected the strength and failure mode of walls. It was found that the strengths of steel walls with silicate board are 1.83 to 2.27 times greater than the strengths of steel walls without sheathing. It was also observed that the strengths of steel walls with silicate board computed according the AISI specification are underestimated as compared to the tested values.
