预应力钢筋混凝土T梁上拱度计算
A calculation method of prestressed concrete T -beam camber
摘要
Abstract
Considering influences of prestress, concrete creep and shrinkages on prestressed concrete T - beam camber, a theoretical calculation method with high -precise was proposed in the paper. Compared with experimental data, the calculation method satisfied the engineering accuracy request, the results will provide reference for the designs and constructions of pre - camber of prestressed concrete beams.关键词
