本研究乃對於冷軋型鋼材所組裝而成的框架試體，配合不同厚度之矽酸鈣板外覆材來進行實驗比較，對於牆試體在單向剪力作用下之行為進行研究，同時針對牆試體的破壞情形、極限強度、勁度、能量吸收、延性比及勁度衰減等探討分析。除此之外，對於純框架試體與具外覆材牆試體上所黏貼的應變片進行應力分析亦為本研究重點之一，故本研究中有選擇數組牆試體及框架試體進行牆體單向或三向的應變片黏貼，以觀察並求得各黏貼位置上之最大主應力、最小主應力及主應力角之變化。
由實驗結果得知，外覆材的使用明顯增加純框架試體上的極限強度，且不同厚度的外覆材比較下，極限強度、能量吸收、勁度衰減等也有明顯的變化。對於結構物中主要耐震牆體合乎本實驗配置者，建議設計延性比可使用2.53。從實驗觀察及應力分析中發現，外覆材在橫向位移不大時以整體構面方式進行抵抗剪力的變形，但當橫向位移大到螺絲產生變形與錯動時，則轉為各單片外覆材的變形情況以進行抗剪力之行為。

This research is concentrated on the structural strengths and behaviors of cold-formed steel wall frames with or without sheathing material under monotonic shear loading condition. Three different thicknesses of calcium silicate board were used to be the sheathing material for the wall frames. The ultimate strength, stiffness, energy absorption, ductility ratio, and stiffness degradation were studied for each test specimen. In addition, two types of strain gages, one way and three ways, mounted on the specimen were used to study the stress distribution of specimen during the test. The maximum and minimum principal stresses of test specimens were also obtained based on the readings of strain gages.

It was observed that the ultimate strength of the wall frame with calcium silicate board is much greater than the strength of the wall frames without sheathing material under the monotonic shear loading condition. And the ultimate strength of wall frame with calcium silicate board increases with increasing the thickness of board. It was also found that the sheathings of wall performed as an entire unit to against the shear force when the horizontal displacement of wall is small. However, when the movement was large and induced the deformation or rupture of the screws, the calcium silicate boards behalf like individual to resist to horizontal forces. In final, it is suggested that the design ductility of the cold-formed steel wall framing system similar to the wall configuration conducted in this study can be assumed to be 2.53.
