Abstract

The state of section of frame beam strengthened with external prestress tendon is analyzed and pointed out that?the effect will be reduced because of the lateral restriction.With the theory of D-value, to consider the structure as anelastomer, computing method of the press force on beams section is addressed.Finally, the carrying capacity of frame beam?strengthened with prestress tendon is further analyzed, and relevant formula is deduced.
- externally prestressing,
- strengthen frame structure,
- concrete structure,
