Method of advanced resultant internal forces for design of modern prestressed concrete structures;

Based on the analysis of internal forces for prestressed concrete structures caused by equivalent load,the definition of resultant internal forces and first internal forces and secondary internal forces are presented and convenient caculation,so as to bring convenient for engineering designing and calculating.

For the use of designing statically indeterminate prestressed structure,the authors presented a method based on the concept of prestress degree of resultant internal forces,that is,the ratio of the compressive stress caused by equivalent loads of prestressed tendon to the tensile stress caused by the external loads.

Utilizing the basic theory of the method of resultant internal forces presented in this article,the practical calculating formulas for the crack resistance capacity of normal section are deduced.
