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.
· AASHTO LTS-13 ASD (6th edition)
· AASHTO LTS-15 (1st edition)
· Canadian CSA S6
· 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 184.108.40.206-1 and AASHTO LTS-15 (LRFD) Table 220.127.116.11-1.
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 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 18.104.22.168 to 22.214.171.124
The fatigue verification for the anchorage rods is also computed according to the specified allowable stress range (DF)TH.
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.

Manually made models
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.
In addition to all the existing section shapes (circular, rectangular, I, L, 2L, T …), the tubular polygonal sections are also available:
The HSE software allows to compute the resistance and/or the thickness of base plates with levelling nuts.
The bending resistance (Mr) of a member is calculated according to clauses 9.5.2 (resistance of the cross section) and 9.5.3 (lateral torsional buckling). The slenderness of the plates is determined according to clauses 8.2.1, 8.2.2, 8.3.1, 8.3.2 and 10.2.1.
The lateral torsional buckling resistance is calculated using the general lateral torsional buckling equation. The equation presented in clause 126.96.36.199 is a simplification of this general equation.
The compressive resistance (Cr) of a member is calculated according to clauses 9.4.1, 9.4.2 and 9.4.3. The slenderness of the plates is determined according to clauses 8.2.1, 8.2.2, 8.3.1, 8.3.2 and 10.2.1.
The torsional buckling stress is calculated using the method presented in clause 13.3.2 of the CAN/CSA S16 code from where the equations of clauses 188.8.131.52 and 184.108.40.206 of the CAN/CSA-S157 code are taken (see commentary C220.127.116.11).
The compressive resistance of a built-up section is calculated according to clause 9.8.2.
The welds have an important influence on the resistance of aluminum elements. The program distinguishes two types of welds which are end welds and in-span welds. Each of these types of welds may be full (affecting the entire cross section) or partial (affecting a portion of the cross section).
In the case of full welds, R Ag, R Ix and R Iy are not used.
In the case of partial welds, ratios must be specified.
This wizard allows generating standard and nonstandard highway sign superstructures of type A1. The standard models are based on the typical plans of the Ministry of Transportation of Quebec. These standard structures are always assumed to be made of aluminum tubes.
The required steps for creating such structures are the following:
1 – Parameters
2 – Beam dimensions
3 – Column dimensions
4 – Beam panels
5 – Column panels
6 – Pedestals
7 – End

IFC (INDUSTRY FOUNDATION CLASSES)
The integration of IFC in the HSE program enables importation of models from a large number of architectural and structural software.
IFC (Industry Foundation Classes) is an open and neutral data format allowing the definition of related classes to all construction objects. It is dedicated to the building sector and aims to software interoperability (all editors, all applications).
IFC is the most widely used protocol for information exchange and sharing between different platforms of BIM (Building Information Modeling).
AutoCAD interface to import and export models by way of a DXF file.
The SDNF (Steel Detailing Neutral File) interface exports beams, columns and braces to SDNF compatible detailing software.
The KISS (Keep It Simple Steel) interface exports beams, columns and braces to KISS compatible estimation softwares.
IFC-Architecture interface for importing models from Revit or other IFC compliant programs.
If required, members subdivision and account for physical elements will be carried out automatically
The solid view of the structure may also be exported when exporting to AutoCAD.
