钢筋混凝土梁长期荷载作用下非线性变形

Non-linear Deflections of Reinforced Concrete Beams Under Long-term Loads

钢筋混凝土梁在长期荷载作用下的非线性变形一直是研究者感兴趣的课题.本文阐述了如何分别考虑荷载、混凝土徐变与收缩对钢筋混凝土梁的变形影响,其中直接应用了作者导出的混凝土徐变和收缩相关系数的实用公式.

The deflection of reinforced concrete beam under long-term loads is non-linear, which has been interesting to civil engineers. This paper describes the deflections of reinforced concrete beams due to loads, creep and shrinkage. The practical expressions of creep and shrinkage factors are derived.
