摘要:
提出超静定预应力结构的综合内力预应力度概念,即预应力筋的等效荷载产生的预压应力与外荷载产生的拉应力的比值.将预应力梁当作压弯构件,提出相应于该预应力度的截面设计方法,从而避开主、次内力的计算.
Abstract:
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. Regarding the prestressed beam as a bar subjected to the bending moment and axial force,a method of section design corresponding to this prestress degree is then presented.So the calculation of both primary and secondary internal forces can be avoided.This design method excels at concept conciseness and calculation simplicity.
