With an established 20-year track record on projects throughout the world, LARSA, Inc. provides the most trusted answers for cable-stay, suspension, stressed-ribbon, curved, skewed and other bridge forms requiring geometric or material nonlinearity or a staged analysis. LARSA 4D Version 7.08.03 is the latest maintenance release in the 7.08 series. LARSA's 4D BRIDGE SERIES software provides a unified 3D finite element environment for the analysis, design and rating of bridges without the need to purchase additional tools.
With an influence surface computed for the entire deck surface, LARSA 4D automatically finds the transverse location of as many lanes as will fit on the surface. View Morteza Rahimi Abkenar, PhD, PE’S profile on LinkedIn, the world's largest professional community. Lanes and vehicles can be defined quickly and include width effects. In all bridge systems (trusses, arches, etc.) Subscribe to the collection. LARSA's 4D Steel Bridge Module provides the ability to move beyond typical grillage analysis to utilize 3D influence surface based live load analysis. From standard one to five axis modules, to multiple bridge/multiple arm modules, we can configure a solution to meet basic needs and challenging custom requirements. Learn more. This task defines the general structure information including geometry, girder type, section, and material. Nevertheless, we have solved the problem convincingly. These existing bridges and roadways are in many cases deigned to cater to regular vehicular traffic and are not suitable of modular heavy haul axle loads.
This module provides practical information regarding the decking options and design considerations for steel LARSA, Inc. For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another.In the structure, the material is subject to tensile and compressive forces. LARSA 4D Steel Bridge Module Tutorial. The Royal Engineer BR-90 family of bridges are built from a range of seven modular panels of advanced aluminium alloy, interchangeable through the various bridge types, to form two interconnecting trackways with a 4 metre overall bridge width and a 1 metre girder depth. LEAP Bridge Steel LEAP Bridge Steel is an integrated modeling, design, analysis, and load-rating software application for straight and curved I-girder and tub-girder steel bridges.
Phone: 800-LARSA-01 Web: www.Larsa4D.com Product: LARSA 4D Description: Advanced software for the design and analysis of bridges and structures; addresses specialized needs for a variety of bridge types including cable, segmental and curved. Bridge Design The widely used modular concept of the SOFiSTiK FE software has especially enabled generations of bridge designers to do their challenging job. Therefore the associated relationship, or fitting, of the members also changes. Steel material is supplied in two product forms – ‘flat products’ (steel plate and strip) and ‘long products’ (rolled sections, either open beams, angles, etc or hollow sections).
Additionally, following our mission to lead innovation in 3D finite element analysis software, LARSA 4D’s new Steel Bridge Module allows our users to optimize design for safer bridges by saving time and reducing cost through the use of a single software that combines refined analysis and …
The Steel Bridge Module is comprised of three main tasks.
the steel components change shape between the fabricated condition, the erected condition, and the final condition. CSiBridge design allows for quick and easy design and retrofitting of steel and concrete bridges. In commercial use for over 25-years, LARSA's rock-solid analysis engine provides the latest in computing technology. This module was edited in 2012 by HDR Engineering, Inc., to be current with the AASHTO LRFD Bridge Design Specifications, 5. th. 1, LARSA 4D BRIDGE Series: 2, LARSA 4D STRUCTURE Series: 3,LARSA 4D Steel Bridge Design & Rating: 4,LARSA 4D Section Composer:
