某工业厂房现浇混凝土楼面由于混凝土抗压强度偏低和负弯距钢筋下移，造成了抗弯承载力不足，出现了大量裂缝。
The low grade of concrete and negative moment reinforcement descending cause the appearance of concrete crack in a workshop floor.
结果表明：纤维布包裹加固钢筋混凝土柱的轴心抗压承载能力和极限应变明显提高；
The results indicate that the confinement of fiber sheet can increase the compressive strength and ultimate strain of reinforced concrete column remarkably.
通常情况下，大幅度提高抗压强度混凝土用于预应力结构比普通钢筋混凝土建造的。
Ordinarily, concrete of substantially higher compressive strength is used for priestess's structures than for those constructed of ordinary reinforced concrete.
