On the basis of equation of cross section and equilibrium equation of the whole structure, a time dependent analytical theory is put forward by taking synthetically the shrinkage and creep of concrete and relaxation of tendon in prestressed concrete structure into account. 以截面平衡方程和结构平衡方程为基础,通过综合考虑混凝土的收缩、徐变及预应力钢束的松驰等时效因素对预应力混凝土结构的影响,提出了一种计算时效影响的理论方法。
We also proposed interval-valued intuitionistic triangular fuzzy cross entropy, and with numerical example shows the interval-valued intuitionistic triangular fuzzy cross entropy reasonable. ( 3) We studied the possible degrees of interval-valued intuitionistic triangular fuzzy, and mainly on account of fuzziness of interval-valued intuitionistic fuzzy sets. 对区间直觉三角模糊数的可能度进行了研究,主要是考虑模糊性对区间直觉模糊集的影响。
