Computers and Structures, Inc. (CSI) is pleased to announce the availability of SAFE 22.7. This release adds AISC 360-22 composite beam design and the latest AISC section database. When working in a model with curved concrete beams, SAFE now has an option to convert these beams to shell slabs. For those working with steel-framed floor systems, serviceability assessment of these floors subjected to walking vibrations has been added following Chapter 7 of the AISC Steel Design Guide 11. In addition, this new version updates the API to support .NET 8.

SAFE is a software tailored for the engineering of elevated floor and foundation slab systems. Slab modeling, analysis, and design procedures feature a suite of sophisticated tools and applications, couple with post-tensioning, punching-shear, and beam detailing, and integrate the influence of soils, ramps, columns, braces, walls (rectilinear or curvilinear), and other interfacial elements. Interoperability with SAP2000 and ETABS allows users to import models, loading, and displacement fields into SAFE for more advanced local assessment of slab systems within larger structures. A 3D-object-based model may originate in SAFE or import from SAP2000, ETABS, or CAD. Templates quickly initiate a model. Grid, snap, chamfer/fillet, trim/extend, circular- and spline-curve controls allow direct drawing of any slab shape. Replication tools streamline modeling for a series of unique slab systems, as was done with Studio Gang’s Aqua in Chicago, Illinois (Reid, Robert L. Chicago Tower’s ‘Wavelike’ Design Features Different Shapes For Every Floor. Civil Engineering Apr. 2007: 22). Up to four simultaneous display windows present the model. Interactive database editing presents definition tables in SAFE and Excel.
