最近接到一個耐震詳評的案子,但在建模時,遇到一個小問題:
若在結構Y向的某些大梁,因為其對到的柱稍微有偏位(結構圖請參考下面的連結)
這種情形在力學行為上,可能得將其視為小梁,只用來傳遞力量。若真是如此,
是否可在ETABS模擬時,將此小梁對到偏柱的那端改成以hinge模擬(moment release),
較符合真實的接合行為。否則此小梁與長向的大梁固接時,不只要考慮長向大梁可能
會形成短梁效應而造成後續的分析困難,也跟真實的接合行為較不吻合?
不知版上的各位先進有何不同的看法或建議,也請各位不吝指教。

計算方式還是全長...不過...我還蠻想問你一下~~就你認知的短

短梁效應..是否就是指短跨距的深梁行為呢?
