![]() The begin of a task can be defined as starting date or starting day. The construction plan is divided into several phases and further into individual tasks, such as concrete hardening, tendon stressing, activation of self-weight etc. In Allplan Bridge, the time as 4th dimension is considered when specifying the construction process. This point grid facilitates copying and mirroring of the tendon in longitudinal and transverse direction. ![]() When calculating the detailed tendon geometry, the program determines these values automatically, using an intelligent algorithm minimizing the friction losses in the stressing process.Ī special point grid is available in the cross-section to ease the specification of the tendon position in the cross-section plane. Selective parameters can be defined as variable. In addition, direction angle and curvature radius of the tendon can be specified in each point. Each 3D Tendon point is specified by the position along the axis, and the position in the cross-section in relation to a reference point. Allplan Bridge 2019 makes it easy to model a wide range of types of pre-stressing: with immediate or later bond, internal and external, longitudinal, transverse and vertical, as well as with non-standard geometry.īased on user-defined 3D points, the program automatically generates the geometry of a tendon along the bridge structure.
