create_tendon_property
Create prestressed tendon property definitions for bridge models, specifying tendon type, duct, steel, area, friction, wobble, and anchorage slip to enable accurate structural analysis and code checking.
Instructions
Create a tendon property definition (创建钢束特性).
Args:
name: Tendon property name (钢束特性名)
material_name: Prestress steel material name, must exist
(钢材材料名，须已通过 create_material 创建)
tendon_type: Tendon type (钢束类型): 0=pre-tension(先张),
1=post-tension(后张), 2=external(体外)
duct_type: Duct type (孔道类型): 1=金属波纹管, 2=塑料波纹管,
3=铁皮管, 4=钢管, 5=抽芯成型
steel_type: Steel type (钢材类型): 1=钢绞线(strand), 2=螺纹钢筋(threaded bar)
area: Tendon area in m² (钢束面积), e.g. 0.00139 for 10Φ15.2 strands
duct_diameter: Duct diameter in m (孔道直径)
friction: Friction coefficient μ (摩阻系数), typically 0.20~0.30
deviation: Wobble coefficient k (偏差系数), typically 0.0015
anchorage_slip: Anchorage slip at each end in m (锚固滑移，两端相同), typ. 0.006
steel_detail: Advanced override, raw qtmodel steel_detail list
(高级用法：直接给出原始 steel_detail 列表，覆盖上述四个参数；
钢绞线=[面积,孔道直径,摩阻,偏差]，
螺纹钢筋=[直径,面积,孔道直径,摩阻,偏差,张拉方式])
