Cloud Sign-in Licensing Details

A precast-concrete box-girder bridge section has been added. Girders can be in contact or separated. Grouting conditions can be considered, with control available in staged construction.

• Speed improvements for nonlinear cases with multi-threaded solver
• Speed improvements in the recovery of analysis results

Web- and flange-plate layouts can be printed for steel I-girder bridges, including comprehensive dimensions and steel-weight quantities. The location of stiffeners and diaphragms that define the shear panels are shown on the drawings. The number of spans shown per sheet can be customized.

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

• 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

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

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

Automated prestress tendon generation based on tendon layouts defined in precast I-girder frame section properties

The quick bridge template has been expanded to allow defining a more complete model, including substructure, superstructure, loading, and design criteria

Bridge deck section superstructure loads provide the ability to easily model barrier, median, sidewalk, haunch, construction, and wearing surface loads

Bridge superstructure design has been added according to the AASHTO LRFD 2017 8^th Edition code

Linear time-history analysis can now be performed in the frequency domain allowing the consideration of frequency-dependent properties, sub-systems, and/or boundary conditions

User-defined concrete box-girder sections can now be updated as area or solid models for analysis and superstructure design and rating

Strain results are now available for shell and solid objects

Bridge superstructure design checks for concrete slab bridges have been implemented according to the AASHTO LRFD code.

The effect of reinforcing steel on the axial creep and shrinkage behavior of concrete in columns and walls is now included in the time dependent staged-construction analysis.

The transverse position of vehicle lanes has been automated for influence-based moving load analysis using floating lane sets.

Measurements

On-screen measuring tools available for measuring length, area, and angles.

The performance of the Bridge Object Response Display form has been enhanced when plotting previously viewed results.

Bridge Superstructure Design

Bridge superstructure design for concrete slab deck sections per Eurocode has been added, including stress, flexural strength, shear strength, and crack checks.

Moment & Shear Releases

Moment and shear releases can now be assigned to the edges of shell-type area objects.

Vietnamese Material Libraries

Vietnamese concrete and rebar material libraries now available.

DirectX

DirectX graphics has been enhanced for quality and speed.

Girder-Only Section Cuts

Girder-only section cuts implemented for steel I-girder bridge sections to capture changes in girder sections, staggered diaphragms, and splice locations in individual girders. This also improves the design and rating of steel I-girder sections by better accounting for the controlling section within each panel.

Hysteresis Models

New and enhanced hysteresis models for nonlinear materials, hinges, and links have been added.

Nonlinear Hinges

Model frame nonlinear hinges as links, allowing for use of nonlinear modal time-history analysis (FNA) for faster analysis.
