小弟在做鋼構時有個模型長下面這樣
(它是斜梁)
(它是斜梁) 一一一⓪
一一⓪一一 ∣
⓪ㄧ一 ∣ ∣
∣ ∣ ∣
∣ ∣ ∣
∣ B2 ∣ B1 ∣
∣一一一一∣一一一一一□ C1 所有交點都是固接!
∣ L2 ∣ L1 ∣
∣ ∣ ∣
∣ ∣ ∣
∣ ∣ ∣
⓪一一一一□一一一一一□
∣ ∣ ∣
∣ ∣ ∣
∣ ∣ ∣
∣ ∣ ∣
∣ ∣ ∣
⓪一一一一⓪一一一一一⓪
一、用連線圖解法來算C1的k時,梁的I/L是要算到B1、L1就好,還是要考慮到B2、L2…
二、etabs有的效長度k是用連線圖解法算出來的嗎? 在Etabs裡面C1的K達三十幾…
我用連線圖解法計算只有4點多左右…
請各位大大幫忙一下~想了好久,搞不懂要怎麼做!
