【關(guān)鍵詞】 鋼筋混凝土 環(huán)形截面 延性系數(shù) 屈服 極限
Calculation for Crosssection Ductile Coefficient of Reinforced Concrete Ring Section Member/Sun Kejian(Inner Mongolia Power Exploration & Design Institute,Huhehaote 010020,China)
Abstract:Starting with the basic assumption while calculating the bearing capacity of the reinforced concrete normal section,the function expression is set up for different stress graphs on the ring section.By using the mathematical method of curve integrals,it derives the mathematical formula to calculate the crosssection ductile coefficient of RC ring section member.
Keywords:reinforced concrete;ring section;ductile coefficient;yield;limit
