已建工程加固中加大截面的措施

摘要

加大截面法是在钢筋混凝土受弯构件受压区加混凝土现浇层,可增加截面有效高度,扩大截面面积,从而提高构件正截面抗弯,斜截面抗剪能力和截面刚度,起到加固补强的作用.%The enlarging section method is to add cast-in—place concrete layer in the compression zone of reinforced concrete flexural members, which can increase the effective section height, enlarge the cross-sectional area, thereby improving the component right section bending, shear capacity and rigidity of section, so that improving the reinforcing effect.
