HSE Highway Sign Structural Engineering
powerful features aiming to enhance users’ productivity
See for yourself the powerful features of the HSE Highway Sign Structural Engineering software.
The HSE software allows users to create different type of structures automatically. In addition, a manually made model mode is available where many different type of structures can be created including high-mast lighting towers, traffic signal roadside signs and others.
The HSE software allows to compute the resistance and/or the thickness of base plates with levelling nuts.
The SAFI HSE software includes the fatigue limit states.
All fatigue parameters for the structure can be set into the highway sign wizard . The CAFT (Constant Amplitude Fatigue Threshold) or (DF)TH for infinite life for the different fatigue detail categories are found in AASHTO LTS-13 (ASD) Table 18.104.22.168-1 and AASHTO LTS-15 (LRFD) Table 22.214.171.124-1.
The Highway Sign Wizard assigns these values when generating the model according to the input data. If the model has not been generated or after the model generation is done, the user can edit this table to change the fatigue parameters for the connection details for both ends of the member.
The Fatigue load combinations are required to compute the equivalent static forces and stresses range due to cyclic loading. The fatigue resistance is specified in AASHTO LTS-15 LRFD clause 11.9 and AASHTO LTS-13 ASD clause 11.9.
This main option activates the input required for fatigue verification. Depending on the type of structures, the fatigue verifications (Galloping, Natural Wind Gust, Truck-Induced Gust) may be activated or not. The user must check on the applicable fatigue loads according to its type of structure based on the requirements of the AASHTO LTS code.
Natural wind gust stresses result from the inherent variability in the direction and velocity of the wind induced airflow around the structure. Natural wind gusts are the most basic phenomena that may induce cyclic loads in lighting and traffic structures. It is generally applied to cantilevered and non-cantilevered overhead sign and overhead traffic signal supports.
Truck-induced gust loads are caused by the passage of trucks under traffic structures. These gusts of wind are caused by moving trucks and create both horizontal and vertical pressure on the structure. The vertical mast arm vibration results in the most critical stresses and therefore only the vertical pressures are evaluated. It is generally applied to cantilevered and non-cantilevered overhead sign and overhead traffic signal supports.
Metric, imperial and mixed units systems are allowed and can be modified at any time. Reports are printed according to any unit system.
Graphical display of seismic and dynamic analysis results
Model size limited only to the physical capacity of the computer.
Objects transparency for various components such as current selection, solid members, plates, surfaces, spatial objects, panels.
The level of transparency may be customized for each type of object from the Display Options command.
Functionalities of the HSE program allow to generate automatically detail elements in an automatically generated mesh perimeter.
These functionalities are specifically related to the refinement area, the opening, the linear constraint and the punctual constraint.
All detail elements added to the HSE model will be automatically connected to the finite element mesh.
The mesh perimeter will also connect any elements already in the model to the mesh perimeter automatically if they are in the plane of the mesh contour.
The program calculates the bending, compression, tension, shear and combined resistance of aluminum based on the results of a linear, P-Delta, non-linear, seismic, dynamic or moving load analysis. Singly symmetric, asymmetric and built-up section shapes are covered for all design codes.
