BSE : BRIDGE STRUCTURAL ENGINEERING SOFTWARE

INTEGRATED STRUCTURAL ANALYSIS AND DESIGN SOFTWARE

BSE SOFTWARE

The BSE Bridge Structural Engineering software is a fully integrated analysis, design and evaluation software for bridges. The software accounts for steel, reinforced concrete, composite, prestressed girder bridges and steel-wood bridges.

This engineering software solution is used worldwide by several notable international companies in production work for building innovative bridges. The BSE software is an advanced structural program based on more than 34 years of Research and Development.

The Bridge Structural Engineering software is a technology built on a powerful user-friendly interface offering comprehensive analysis options and intuitive modeling features. The advanced structural analysis of the BSE software allows the user to achieve specialized analyses crucial to any projects related to the bridge industry.

The BRIDGE STRUCTURAL ENGINEERING program allows to analyze, verify, evaluate and design 2D and 3D bridge models of any type and size subjected to standard or non-standard moving loads. The BSE BRIDGE performs multiple simultaneous or non simultaneous standard and non standard moving loads analysis on simple and complex trajectories. The program includes a comprehensive library of over 25 standard trucks and a moving load editor for user defined trucks and trains.

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.
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.

COMPREHENSIVE STRUCTURAL ANALYSIS OPTIONS

FEA Finite Elements Analysis, Static Analysis, Linear and Nonlinear Analysis, P-Delta Analysis, Natural Frequency Analysis, Static Equivalent, Seismic and Dynamic Analysis, Time-History Analysis, Modal Analysis, Spatial Objects and Spatial Loads, Buckling Analysis, Spectral Analysis, Advanced Section Stress, Torsion and Warping, Built Up Sections, Catenary Cables, Diaphragm Analysis, Notional Horizontal Loads, Loads and Load Combinations.

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.

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 BSE, the user can create a catenary cable by associating a cable type section to a member.

DIRECT ANALYSIS METHOD

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 BSE 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.

ANALYSIS ANIMATION FEATURE

ANIMATION FEATURE

The BSE software allows users to animate results from different types of analysis such as:

-Static Linear Analysis
-Static P-Delta Analysis
-Buckling Analysis
-Natural Frequencies Analysis
-Seismic and Dynamic Analysis

The results are scaled by a linearly increasing factor until the unity factor is reached. The user can detect which parts of the model undergo the most displacements or internal forces by seeing the variation of intensity across the model.

STATIC LINEAR AND P-DELTA ANALYSIS

With the BSE software, users are able to animate various static linear and P-Delta analysis results such as the:
-Structure displacements
-Internal forces
-Stresses
-Support reactions.

ANIMATION FOR A BRIDGE MODEL

In the bridge results menu, animating the envelopes helps minimizing the amount of information on the screen. The user can focus on the most solicited regions of the model. As the animation evolves, the final results are displayed and the global envelopes are displayed.

FREQUENCY & 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.

TIME HISTORY

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 the user 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. The user can focus on the most critical regions of the model.
