摘要
在不同强度等级的高强混凝土和配筋率的偏心受压短柱试验基础上,通 过对高强混凝土极限压应变的取值、受压区混凝土应力-应变曲线形式的选 取及等效应力图形简化处理,建立起一套计算方法,并推导了相应的计算公 式.本计算方法,对工程设计和计算具有一定理论和应用价值.
Based on the tests of eccentric compressive short columns for different concrete strength and steel content, a calculation is established and a formula is derived,with respect to the maximum pressure strain of high strengh concrete, by choosing the forms of the stress-strain curve of compressive concrete and with the treatment of equivalent stress diagram, etc. This calculation method is of theoretical and acceptable value to project design and calculation.
