The HSE HIGHWAY SIGN STRUCTURAL ENGINEERING Software is an automated Highway Sign Structures generation analysis and design program for latticed Highway Sign Structures, Overhead Sign Structures, Gantry structures, Cantilevers, Traffic Signals and Luminaire Support Structures.
The HSE software is a high-end parametric technology for the generation and design of various Sign Structures. It offers powerful and productive features for generating many types of latticed structural models and automated tools for determining wind and ice loads as well as any relevant design parameters such as slenderness ratios and force coefficients.
This engineering software solution is used worldwide by several notable international companies in production work for building innovative sign structures.
The HSE is a robust and reliable structural software based on more than 35 years of Research and Development. The program, designed with the latest technological innovations in its field, is equipped with a sophisticated and user friendly graphical interface.
The HSE program can calculate the resistance and various design parameters of all elements of a Highway Sign Structures model according to the Canadian, American and European Steel codes.
The program supports the required specifications of the AASHTO LTS-13 ASD (6th edition), AASHTO LTS-15 LRFD (1st edition) and AISC 360-10 LRFD. The program supports the American Aluminum AA ADM-2015 (LRFD) and Aluminum AA ADM-2015 (ASD) for general structures and the Canadian aluminum codes CAN/CSA-S157.
The HIGHWAY SIGN ENGINEERING program supports ice loads, wind loads which can be defined according to various distribution methods ranging from uniform distribution and user defined distributions to sophisticated methods as the one proposed in the IEC-826 document.
The ice loads and wind loads are automatically distributed to the latticed structure and to the sign panels.
· Automated self-weight
· Automated wind and ice loads
· Automated Concentrated and distributed loads
· Automated fatigue
· Thermal gradient loads
· Seismic analysis capabilities
· Automated Load combinations
The HSE software allows the user to create load combinations.
A load combination results in an algebraic combination of distinct basic loads.
Each basic load is multiplied by a load factor. The resulting load combination acts on the structure to generate a specific structural response.
The load combination wizard in the program also allows creating load patterns.
The load combination wizard generates load combinations according to NBCC, UBC, ASCE 7, BOCA, Eurocode and ECC.
Loading for joints, members including concentrated, uniform, trapezoidal and thermal loads.
Pressure or concentrated floor loads with two-way, one-way and truss distribution using triangular or quadrilateral surfaces.
Pressure or concentrated loads on finite element plates.
Gravity loads in any global direction calculated by the program.
Imposed displacements at any joint.
User defined load combinations.
· Fatigue verification according to chapter 11 of AASHTO LTS-13 (ASD) and AASHTO LTS-15 (LRFD).
· Verification of stresses according to the Constant Amplitude Fatigue Threshold (CAFT).
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 126.96.36.199-1 and AASHTO LTS-15 (LRFD) Table 188.8.131.52-1.
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.
Generating Fatigue Loads
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. Users must check on the applicable fatigue loads according to its type of structure based on the requirements of the AASHTO LTS code.
Automated Structural Models
Automated Structural Models
The HSE software allows users to create different type of structures automatically. In addition, a manually made model mode is available where many different types of structures can be created including high-mast lighting towers, traffic signal roadside signs and others.
Latticed column with 4-sided latticed beam
Latticed column with 3-sided latticed beam
Pole column with 4-sided latticed beam
Pole column with 3-sided latticed beam
Pole column with flat latticed beam
Manually made models
In addition to all the existing section shapes (circular, rectangular, I, L, 2L, T …), the tubular polygonal sections are also available:
Powerful beam generator
Many features for the generation of beams are available to HSE users. For example, it is possible to select different panel models (Warren, Pony Warren or Pratt) for the beam diagonals. These panel models can be reverted with the Discontinuous diagonals option.
When the invert opposite face option is unchecked, it is possible to align the arrangement of the diagonals on the opposite face of the beam. It is possible to specify different panel models for the vertical faces of the beam and for the horizontal faces of the beam. By default, horizontal panels are identical to vertical panels.
It is possible to specify different panel models for the vertical faces of the beam and for the horizontal faces of the beam. By default, horizontal panels are identical to vertical panels.
The HSE software provides various options for the interior diagonals such as:
At ends only
By default, the interior diagonals are repeated at each panel. When this option is checked, the diagonals are generated only at the segment ends.
The first and last interior diagonal of a segment can be offset toward the inside of the beam by a distance of ΔD.
The HSE software also allows to automatically generate beams made of single angle sections.
Computation of base plates
The HSE software allows to compute the resistance and/or the thickness of base plates with levelling nuts.
· Structure design for compression, tension, bending, shear, torsion and warping, slenderness, deflection and fatigue.
· Anchor rods verification.
· Base plate design and verification.
The command Highway Sign Anchorages allows to define the input data for the anchorages.
The anchorage resistances and limit states are computed according to the following clauses according to the selected standard.
-AASHTO LTS-15 (LRFD) clause 5.16.3
-AASHTO LTS-13 (ASD) clauses 184.108.40.206 to 220.127.116.11
The fatigue verification for the anchorage rods is also computed according to the specified allowable stress range (DF)TH.

Seismic and dynamic analysis
Users are able to animate various static linear and P-Delta analysis results such as:
Frequency and Buckling
The frequency and buckling analysis provide multiple mode shapes describing multiple behaviors of the structure. With large models, the animation is helpful to discern and understand the mode shapes. It is easier to determine if the buckling mode is a local or global phenomenon. It also provides a very accurate interpretation of the participating mass of each mode in a seismic spectral analysis.
The animation function displays every saved time-step to provide an accurate representation of the displacements, velocities, accelerations and internal forces acting on the structure.
This will provide users a better understanding of the structure behavior during the dynamic event, such as finding the critical time of the dynamic loading.
Animating the envelopes helps minimizing the amount of information on the screen. Users can focus on the most critical regions of the model.
