摘要: 采用钢筋应力计量测钢筋混凝土支撑轴力时,收缩应力和温度应力修正是必要的。结合上海浦东某实际工程,从理论上和实测中对支撑轴力中收缩和温度应力进行研究。结果表明,收缩引起的应力相当于整个支撑轴力的1/3,而温度变化引起的最大应力相当于支撑轴力的1/5。Abstract: It is necessary to consider the influence of shrinking and temperature stresses when using reinforced stress to measure reinforced concrete strut axial forces. According to an engineering practice in Pudong, Shanghai, both the theoretical analysis and in-situ test are studied. The results show that the shrinking and maximum temperature stresses correspond to 1/3 and 1/5 of the total strut axial forces respectively.
