想問一下
傾角變位法大家當初學的時候也花了很多時間嗎?
這個法不知道為什麼就覺得跟我磁場不合
我重聽了兩次還是不太能掌握題目
主要是購材角那部份我不太會列比例
還有傾角變位法那通式是一定要記起來的嗎?感覺滿占腦內的記憶體
她有基本型 一端固定一端roller 對稱型 反對稱型
我目前是只有用到前兩個
毛毛蟲是說她是靜不定剛架的救援投手,真的有那麼威嗎?
因為我很多題目其實用單位力法就可以解出來了
還是這個法只是拿來驗算用的?
另外想問一下短柱效應
http://ppt.cc/2_k_
大概類似這種題目,EL柱填補一公尺的水泥牆之後就變短柱了
最後算出來他所受的彎矩與剪應力都比未填充時來的大
所以地震來時短柱會先垮
既然這樣為什麼還要弄成短柱呢?填充水泥牆也是要錢的
