CSI Bridge 2018 Advanced with Rating v20 build 1384 [Size: 510 MB for x86 - 485 MB for x64] ... Loading: The transverse position of vehicle lanes has been automated for influence-based moving load analysis using floating lane sets. Analysis: 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. + A pure event-to-event option has been added for nonlinear static analysis. Bridge Design: Bridge superstructure design checks for precast I-girder and precast U-girder bridges have been implemented according to the BS 5400 British code. + Bridge superstructure design checks for concrete slab bridges have been implemented according to the AASHTO LRFD code. + Bridge superstructure design and rating of steel I-girder bridges now considers local girder effects when the bridge object is updated as a spine model. + Superstructure design of concrete box-girder bridges according to AASHTO LRFD now offers the Modified Compression Field Theory (MCFT) method, including torsion, for performing shear design according to AASHTO 22.214.171.124.2. Modeling: An option has been added to control the limiting negative stiffness ratio for frame hinges. Drafting: On-screen measuring tools for measuring length, area, and angles have been added.
