摘要: 笔者在文中推导了钢筋砼轴心受压构件在长期荷载作用下应力变化的计算公式,并根据资料验算,得出了当构件配筋率达到一定值时,构件将开裂的结论.

关键词: 徐变, 开裂, 长期荷载

Abstract: This Paper gives the formula about stress variation of reinforced concrete columns over long periods of time while under constant load, then, by using the formula, the conclusion of columns crack under certain reinforcement ratio be revealed also.

Key words: creep, crack, constant load
