The primary user manual for CSiBridge is found within the software itself by selecting Help > Documentation > Manuals . For a deep dive into the underlying mechanics, you should refer to the CSI Analysis Reference Manual , which is the foundational guide for all CSI products (SAP2000, ETABS, and CSiBridge).  Core Manuals & Documentation  CSiBridge documentation is split into several focused manuals to help you navigate different engineering stages:  Introduction to CSiBridge : A starter guide for modeling concrete box girder and precast concrete girder bridges. Analysis Reference Manual : Detailed documentation on the algorithms, assumptions, and coordinate systems used by the SAPFire Analysis Engine . Key Features and Terminology : Defines the core workflow, from parametric object-based modeling to lane and vehicle definitions. Superstructure Design & Bridge Rating : Specific guides for designing bridge decks and performing load ratings according to codes like AASHTO . Seismic Analysis and Design : Covers automated seismic design steps and nonlinear analysis procedures.  Key Learning Resources  Beyond the PDF manuals, CSI provides interactive resources to speed up your learning curve:  The Bridge Wizard : An in-software tool that provides step-by-step instructions for creating a complete bridge model, ensuring all necessary components are defined. Watch & Learn Series : Official video tutorials available on the CSi America website that cover introductory modeling, moving loads, and advanced design. CSi Knowledge Base : A searchable online portal with technical papers, FAQs, and test problems for CSiBridge . CSI API Help : For developers, a dedicated help file documents the hundreds of API functions used for cross-product tool development.  CSiBridge | BRIDGE ANALYSIS, DESIGN AND RATING
For an official and comprehensive "paper" or guide, the CSI Analysis Reference Manual is the primary technical document. It covers general technical topics fundamental to modeling, analysis, and design for CSiBridge. Core Manuals and Documentation CSI Analysis Reference Manual : This is a comprehensive, searchable PDF covering the general technical topics for modeling and analysis across CSI software. It can be accessed within the program via Help > Documentation > Manuals > Analysis Reference Manual . Introduction to CSiBridge : An essential guide for new users that explains basic modeling steps, loading (including lanes and vehicle definitions), and analysis output. CSiBridge User Guide and Tutorial : A detailed document providing a step-by-step example project, typically focusing on a concrete box girder bridge. CSiBridge Knowledge Base : An online resource that hosts the most current documentation, including CSiBridge Tutorials and release notes for specific versions like v24.
