THE DESIGN OF EXTERNALLY PRESTRESSED CONCRETE BEAMS WITH U-SHAPED CROSS-SECTION
-
摘要: 复杂截面的预应力混凝土梁需通过积分计算几何特征,不利于工程设计。通过一体外预应力U型截面梁的工程实例,介绍了应用等效换算截面进行设计的方法,以及运用约束次内力法进行体外预应力结构设计的方法。Abstract: In the design of prestressed concrete beams, Intergral calculus is needed in calculating the geometric properties of irregular cross section. By presenting a case of externally prestressed beams with U-shaped cross section, a section equivalent conversion method is introduced, and the design process of externally prestressed concrete structure using the method of secondary interior force under restraint are also presented.
