axial unit ratio 中文意思是什麼
axial unit ratio
解釋
軸單位比-
When the axial compression ratio increases more than 0. 42, the variation of the displacement ductility ratios is small ; when the stirrup ratio per unit volume increases more than 1. 9 %, the displacement ductility increases slowly ; with increasing the shear span ratio a, the displacement ductility increases for, < 1. 5, decreases for > 1. 5
當軸壓力系數增加到0 . 42以後,位移延性的變化較小;體積配箍率增加到1 . 9 %后,位移延性的增長減緩;當剪跨比小於1 . 5時,型鋼混凝土柱的延性系數隨剪跨比的增加而提高;但當剪跨比大於1 . 5時,隨著剪跨比的增加,型鋼混凝土柱位移延性系數有所降低。
