HSE HIGHWAY SIGN Structural Engineering Software

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, 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 33 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.

SPATIAL OBJECTS AND SPATIAL LOADS
Spatial objects are used to model non-structural secondary elements attached to the structure. These elements add no stiffness to the existing model. Loads applied to spatial objects are transferred to the structure through one or more attach joints. The loads are transferred using a “rigid plate” approach. Concentrated, pressure and wind loads may be applied to spatial objects. The figures below shows a spatial object loaded vertically and horizontally attached to a cantilever column. Also, it shows the deformations and biaxial moments induced by the loads transferred by the spatial object.

Direct Analysis Method (DAM) available for AISC 360-16 and AISC 360-10 standards. The options for the Stability Design Method are Direct Analysis Method (DAM) and Effective Length Method (kL).

TORSION AND WARPING
The TSE software considers restrained warping for the torsion of thin-wall open sections. Notice that this phenomenon is not included in most commonly used frame analysis programs. Almost all frame programs in practice use St-Venant torsion theory ignoring the effects of restrained warping.
CATENARY CABLES
The catenary cable element is a highly non-linear element used to model the catenary behavior of a cable suspended between two points under the effect of its self-weight. This formulation accounts for the non-linearity due to large displacements.A cable has no bending, shear, compression or torsion stiffness. Due to this fact, the fixities at the ends are ignored; the cable is always treated as member acting in tension only.In the interface of the TSE, the user can create a catenary cable by associating a cable type section to a member.
LOADS AND LOAD COMBINATIONS
The software allows the user to create load combinations.
A load combination results in an algebric 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.

FILE IMPORT AND DATA EXCHANGE

IFC (INDUSTRY FOUNDATION CLASSES)

The integration of IFC in the TSE 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

ALUMINUM STRUCTURES VERIFICATION

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.
•Aluminum design codes
• Member Attributes – Aluminum
• Bending Parameters
• Compression and Tension parameters
• Welds parameters
• Recalculate
• Redesign selected members
• Design summary

BENDING

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 9.5.3.2 is a simplification of this general equation.

COMPRESSION

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 9.4.3.2 and 9.4.3.3 of the CAN/CSA-S157 code are taken (see commentary C9.4.3.3).

The compressive resistance of a built-up section is calculated according to clause 9.8.2.

WELDS

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.
