The Steel-Wood Bridges software is an entirely automated parametric program for the design and the evaluation of steel girder bridges with wood decks. The program performs the design or the evaluation of such bridges according to the Canadian CSA S6-19 code including chapter 14 regarding bridge evaluation.
The Steel-Wood Bridge (SWB) program is an automated engineering tool for analyzing one- and two-lane steel girder bridges with wood decks using both standard and parametric steel section shapes. It includes libraries of standard metric and imperial material properties, with options to create customized materials.
The software supports analysis with standard CL-625 and CL-625-ONT trucks for road classes A, B, and C, and also allows for custom truck configurations. Element dimensions, such as transverse beam spacing and timber sizes, default to common values but can be easily edited as needed, with customizable default settings.
The Steel-Wood Bridge (SWB) software is robust tool developed by SAFI Structural Software. Established in 1986, SAFI is a technology-driven company designed to empower engineers to tackle complex structural challenges with ease. With a rich history of 38 years of continuous development, the SWB software stands as an example of innovation in the bridge industry.
Take the next step to discover the Steel-Wood Bridge (SWB) Software by completing the following form. One of our experts will get in touch with you shortly. We look forward to assisting you with your inquiries and providing you with the information you need.
-The Steel-Wood Bridges (SWB) program can analyze one and two lanes bridges using standard or parametric steel section shapes.
-Libraries of standard metric and imperial material properties are available. Customized materials can also be created.
-The program uses the standard CL-625 and CL-625-ONT trucks according to the road classes A, B and C. Customized trucks can also be created.
-All dimensions of the elements defaults to commonly used values. These dimensions, such as the spacing of transverse beams and dimensions of timbers can be edited whenever required.
-Default values can also be customized.
-The Steel-Wood Bridge (SWB) design capabilities are used to optimize a bridge or to calculate the resistance of the steel and wood elements of known dimensions.
-The entire design process is automated with respect to the user parameters.
-The weight of the elements, the effect of the skew angle, the lateral stiffener beams or diaphragms is determined automatically.
-In most cases where the bridge design follows the established standards, the only data required to design such bridges are the length of the span and the number of lanes.
-The program calculates the resistance of the steel beams and the resistance of the wood parts such as the transverse shear and bearing capacity of the transverse beams.
-The deflection of the bridge girders is also considered.
-The Steel-Wood Bridge (SWB) software performs the evaluation of an existing steel-wood bridge according to the chapter 14 of the CSA S6-19 code. The equations specific to the MTQ are also included in the program.
-Unlike for the design of a bridge, the evaluation of an existing bridge requires a larger number of data to fully describe the geometry and dimensions of the elements of the bridge.
-The program calculates the resistance and the live load capacity factors (F) of the steel beams and the resistance of the wood parts such as the transverse shear and bearing capacity of the transverse beams.
-When required, recommended signs are displayed.
-The deflection of the bridge element is also considered.
-The evaluation report and design report are printed in a Microsoft Word compatible file format.
-These reports include all relevant design and evaluation intermediate results, limit states and live load capacity factors as well as a sketch of the bridge and recommended posting if any.
