Pre-stressed concrete beams following stretch is one of the structural solutions are popular applications in the construction work has rhythm changes. Continuous beams with constant cross section will no reasonable ability and economic strength to span large changes in size. The problem is the need to change the beam matching section of the beam aperture rhythm changes.
Therefore, for the construction design engineer should choose the shape, the size of which structural system beam systems, in addition to satisfactory performance of the architecture should also reasonable solution in actual structural design, besides solutions for cable layout beam orbit continuous pre-stressed concrete with section changes also need special attention in order to achieve structural efficiency.
method C-line path in this study is the solution enables designers can evaluate and adjust the orbit to minimize cable to the lowest level of secondary effects of torque to the ability to work and the stability of the structure, providing high efficiency for texture.
