中文摘要 | 組合樑近被發現為一挫屈後不穩定結構。本文透過柯依特和布第安斯基二氏所發 展的一般性彈性挫屈原理,找出3接頭組合樑的挫屈載荷,挫屈後行為和峰值載荷對幾何不 完善等的數學解析解,其數值結果和另以數值法求解平衡方程式和非線性邊界條件者同。 |
英文摘要 | In this paper, we apply the powerful Koiter-Budiansky's general theory of buckling of elastic structure through the language of functional analysis and perturbation technique to find the analytical expressions for buckling load, post-buckling behavior, and peak load versus imperfection for 3-connection built-up columns, an imperfection sensitive structure. The asymptotic expressions between the load-shortening relationship for a perfect column and the load-shortening-imperfection relationship for an imperfect column are derived. The results are consistent with the existing numerical solutions. |
