预应力混凝土设计软件PKPM/PREC和MIDAS/Gen在计算中各有优点和不足。结合贵阳北站工程,从次梁预应力筋对主梁设计内力的影响、梁预应力筋锚固位置对梁端设计内力的影响、梁预应力筋锚固位置对柱子设计内力的影响、梁端有剪力墙时对梁预应力筋效率的影响等几个方面进行研究分析。发现在布置预应力钢筋时如果不考虑这些因素可能会导致安全问题。所以在计算复杂的预应力框架结构时应采用多个软件进行复核。
Prestressed concrete design software PKPM / PREC and MIDAS / Gen have their own advantages and disadvantages in the calculation. Combined with the project of Guiyang North Railway Station, from the secondary beam prestressed tendons on the design of the internal force of the beam, beam prestressed tendons anchor position on the internal force of the beam design, the anchorage of beam prestressed tendons column internal forces, Shear wall when the beam prestress tendon efficiency and other aspects of research and analysis. It has been found that failure to account for these factors in laying prestressed reinforcement can lead to safety problems. Therefore, in the calculation of complex prestressed frame structure should be used to review multiple software.
