摘要
本文给出了矩形截面无粘结部分预应力混凝土叠合梁裂缝宽度的试验结果 .在此基础上 ,结合无粘结部分预应力混凝土梁及普通混凝土叠合梁的已有成果 ,提出了裂缝宽度计算公式 .经与试验结果验证知 ,这些公式计算精度较高 。
This paper presents the experimental results of the crack widths of 20 unbonded partially prestressed concrete composite beams with rectangular cross section. According to the research results of unbonded partially prestressed concrete beams and reinforced concrete composite beams, two kinds of formula for crack width of unbonded partially prestressed concrete composite beams are proposed. The formulas are verified by experimental data.
