摘要(中) |
本研究乃對於冷軋型鋼立柱束制外覆材的行為進行探討,所採用的試體為僅有外覆材受壓內含支撐立柱的試體(FS),共有18組試驗以配合不同厚度之矽酸鈣板與螺絲間距來進行試驗比較,並與立柱與外覆材同時受壓試體(FF)與僅有立柱受壓但具外覆材束制(FC)之試體進行相互探討。爲了解外覆材矽酸鈣板基本力學性質,本研究亦進行一系列的材料試驗包含:材料彈性模數(E)試驗與材料剪力模數(G)試驗。 由試驗結果得知,不同厚度的外覆材矽酸鈣板所量測之單位體積重會有所不同,也因此其彈性模數與剪力模數亦有相當的差異,以板厚12
mm為例其單位體積重最低,代表材料孔隙越大,故會產生E、G值較小的原因。就外覆材與立柱相互束制的關係而言,僅有外覆材受壓內含支撐立柱試體(FS)與僅有立柱受壓但具外覆材束制試體(FC)強度相加,其差距較單根立柱所試驗出之抗壓強度加上僅有外覆材受壓內含支撐立柱試體(FS)強度之差距來的小,而更接近立柱與外覆材同時受壓試體(FF)強度,但還是會有略為高估的情形。 |
摘要(英) |
The purpose of this
study was to investigate the behavior of constrained sheathing material
of cold-formed steel stud. This study carried out tests and comparison
on test specimens with supporting stud and pressurized sheathing (FS) by
using calcium silicate boards of different thickness and different screw
spacing, and compared the results with test specimen whose stud and
sheathing were under pressure simultaneously (FF) and test specimen with
pressurized and constrained sheathing (FC). For the purpose of having a
better understanding of the mechanical properties of calcium silicate
boards with sheathing, this study also conducted a series of material
tests, including material elastic modulus test (E)and material shear
modulus test(G). Test results showed that: the unit volume heavy of
calcium silicate boards with sheathing was different, leading to
considerable difference in their material elastic modulus and material
shear modulus. Taking board with a thickness of 12mm as example, its
bulk weight was the lowest, which meant its material pore was very wide.
As a result, and its E and G values were relatively small. In terms of
the mutual constraint relation between sheathing and stud, the result
gained by adding the strength of test specimen with supporting stud and
pressurized sheathing (FS) and the strength of test specimen with
pressurized and constrained sheathing (FC) was lower than the result
calculated by adding the compression strength of a single stud and the
strength of test specimen with supporting stud and pressurized sheathing
(FS), and was very close to the strength of test specimen whose stud and
sheathing were under pressure simultaneously (FF), although it might be
overvalued. |
