Integrated design for concrete components

Expand LARSA 4D's BRIDGE SERIES software platform with concrete analysis and design enhancements to rapidly perform Biaxial Interaction Analysis, Moment Curvature Analysis, and detailed Code Check.


LARSA 4D C-Suite

LARSA 4D C-Suite delivers a new level of efficiency and precision in concrete analysis and design. More than just a tool, it’s a comprehensive solution that integrates advanced material models, cross-sectional properties, and deep structural behavior insights.
Engineers can calculate moment capacities using the Moment Curvature Analysis Tool, capturing material events like concrete cracking and rebar yielding. The Biaxial Interaction Tool determines ultimate section capacity, even with complex reinforcement or cutouts, and generates yield surfaces for inelastic analysis. With support for AASHTO LRFD (7th–9th Editions) and IRC codes, the Code Check Tool automates compliance checks for piers and girders, offering both quick pass/fail feedback and detailed reporting. C-Suite equips engineers with the confidence to design safer, code-aligned structures.

Code Check Tutorial

LARSA 4D C-Suite's Code Check Tool performs comprehensive design code checks for reinforced and prestressed concrete piers and I girders in a unified, intuitive environment. From evaluating individual bridge elements to verifying full-structure compliance, the tool enhances design confidence through precise analysis, integrated workflows, and code-aligned results. Combining material property limits, reinforcement configurations, shear capacity, and crack control criteria, the Code Check Tool lets users automate critical design checks and perform biaxial interaction analysis and generate detailed, code-referenced reports ensuring structural demands fall within capacity limits.

Biaxial Interaction Analysis Tutorial

LARSA 4D C-Suite's Biaxial Interaction Analysis Tool allows engineers to evaluate the combined effects of axial force and biaxial bending (My-Mz) in structural sections. By computing the full 3D P-MY-MZ capacity surface, C-Suite's Biaxial Interaction Analysis enables users to visualize the interaction between axial and bending forces and assess whether structural demands fall within safe limits. Designed for engineers performing nonlinear analysis and capacity checks on reinforced or prestressed concrete, steel, and composite sections, the tool provides a deeper understanding of section performance under complex loading.

Moment Curvature Analysis Tutorial

LARSA 4D C-Suite’s Moment Curvature Analysis Tool enables advanced structural design and nonlinear analysis of beam and column elements near their moment capacity. Engineers can generate moment curvature curves for single or multiple axial force values, evaluate sectional performance, and review detailed outputs including stress-strain behavior, internal force distribution, and key material events such as cracking, yielding, and rupture. The tool also supports the export of bilinear hinge properties for use in nonlinear pushover analysis, ensuring seamless integration into performance-based design workflows.
