Structural Analysis with Integrated Concrete and Steel Design

Analyze and design simple or complex steel and concrete structures to numerous international design codes.

Trusted by thousands of structural engineers worldwide for over 30 years, S-FRAME is the design and analysis software of choice for moment frames, braced frames, trusses, bridges, office and residential buildings, skyscrapers, industrial buildings, plate/shell and fabric structures, cable structures and more.

S-FRAME features numerous advanced analyses, a variety of hysteretic material models, flexible load combination methods and staged construction, all using fast and accurate sparse solver technology.

Design and Productivity tools include fully integrated concrete and steel design modules, BIM/DXF integration, and a comprehensive results validation and visualization tool.

S-FRAME's intuitive user interface allows users to easily experiment with multiple design alternatives within a single model to yield robust designs with comprehensive reports.

New for Release 2017

New capabilities in S-FRAME Analysis R2017 are designed to enable the engineer to quickly generate complex models via help the engineer generate more detailed, enhanced analysis results for steel members and
Automatically convert 1D beam members to 2D shell elements for enhanced analysis
New R2017 Modeling Features
Member to Shell Conversion for enhanced analysis
Models with both steel and concrete members (1D prismatic or linearly tapered) can be automatically converted into equivalent shell models, with member loading converted to equivalent shell loading.
Resulting Pier forces diagrams are relative to the original member element coordinate system.
Convert joints to equivalent shell models to facilitate moment connection modeling with and without stiffeners
Member end connectivity (pinned, partially fixed, hysteretic, etc.) can be optionally be preserved when converting to equivalent shell models
Rigid Body Constraint, a new constraint type enables users to model complex geometry by:
Modeling rigid connections. e.g. where several beams and/or columns frame together
Connecting together different parts of the structural model that were defined using separate meshes
Connecting 1D elements (member/truss) that are acting as eccentric stiffeners/re-bars to 2D elements (shells)
Rigid Body Panels: a new panel type
Rigid Body Panels enable users, among other applications, to easily enforce the condition that plane sections remain plane when converting members to detailed 3D shells.
Pass Through Force Connection Design Tool for calculating the Pass-Through/Transfer Forces
Monitor load paths to better facilitate connection design
Member end forces are summed up and transformed to global or joint coordinate system (transfer forces)
Users can control which members contribute to a connection component and can define custom member arrangements to connections
Other Modeling Improvements
Meshing: Mesh generators now automatically locate and correct for overlapping panels, preventing duplicate mesh panels.
Select members based on member length
When subdividing groups of members or shells of different size, there is a new option to average the subdivisions to make them as close as possible to the same size.
Circular, Rectangular and Wall panels automatically create the panel polygon using grid intersections.
Increase to the number of allowable area load sub polygons by a factor of 3.
