我不會附圖,抱歉。我盡量用說的解釋清楚,我的問題是,混凝土高540*寬300的面積內
,有4個圓鋼釘,直徑為25MM,分布在面積靠近底部60MM(圓心到混凝土面積底部),如
何計算轉換斷面(用E1/E2=N的方法),我只會算兩種材料都是矩形且是併在一起的,但如
果一種材料包覆另一種的我就不會了。小弟目前土木2年級,爬過文找不到我要的資料,
課本也看不太懂。
題目:the reinforced concrete beam shown is subtect to a positive bending
moment of 175KN‧m.knowing that the modulus of elasticity is 25GPa for the
concrete and 200GPa for the steel,determine(a)the stress in the steel,(b)the
maximum stress in the concrete.
請大大告訴我這種題目如何解。(我有詳解了,但就是看不懂)拜託。
