CSI Bridge v21.1

CSI Bridge v21.1


Computers and Structures, Inc. (CSI) is pleased to announce the availability of Bridge version 21.1.0. New enhancements have been implemented in latest update related to Bridge Modeling, Analysis and Bridge Design.

CSiBridge 21.1.0 Enhancements – Release Date: 22 Aug 2019:

Bridge Modeler

Quick bridge template enhanced to remember previous settings and provide additional options when creating a new bridge model

Bridge modeler can now generate multiple pairs of braces for steel cross-frames

Bridge modeler now allows detailed definition of foundations at the bottom of bent columns, including soil springs


Analysis can now run multiple load cases in parallel. This is particularly efficient for considering large suites of earthquakes in Performance-Based Design.

Bridge Design

Concrete superstructure design according to the Indian IRC-2011 code for flat slab and T-beam bridge sections

Concrete superstructure design according to the Indian IRC-2011 code now calculates the required reinforcement quantity.

Detailed reports for CAN/CSA S6 steel I-girder bridge strength design requests

Detailed reports for AASHTO steel U-girder bridge strength and service design and rating requests


Faster display of results from modal time-history load cases, including FNA, for large models with many modes.

CSiBridge is specialized analysis and design software tailored for the engineering of bridge systems. Suspension, cable-stay, elevated-roadway, and other types of bridge systems may be modeled and designed to suit any one of a variety of purposes, including means for crossing water, linking points between shear terrain, or extending over highway infrastructure. Customized controls and features integrate across a powerful object-based modeling environment to offer an intuitive, practical, and productive computational tool for bridge engineering. Advanced modeling features and sophisticated analysis techniques account for dynamic effects, inelastic behavior, and geometric nonlinearity. Code-based templates streamline the engineering process from model definition through analysis, design optimization, and the generation of comprehensive output reports. CSiBridge is the premier software for bridge engineering.

CSiBridge – 11 Modeling using Staged Construction

Founded in 1975, Computers and Structures, Inc. (CSI) is recognized globally as the pioneering leader in software tools for structural and earthquake engineering. Software from CSI is used by thousands of engineering firms in over 160 countries for the design of major projects, including the Taipei 101 Tower in Taiwan, One World Trade Center in New York, the 2008 Olympics Birds Nest Stadium in Beijing and the cable-stayed Centenario Bridge over the Panama Canal. CSI\’s software is backed by more than three decades of research and development, making it the trusted choice of sophisticated design professionals everywhere.
