Structural Analysis with Integrated Concrete and Steel Design

Model, analyze and design structures regardless of geometric complexity, material type, loading conditions, nonlinear effects or design codes. Easy to use for simple projects and powerful enough for the most complex.

Trusted by thousands of structural engineers worldwide for over 35 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 Analysis supports linear, nonlinear and advanced analyses, a variety of hysteresis material models, flexible load combination methods and staged construction, all using fast and accurate sparse solver technology.

The S-FRAME modeling interface with advanced mesh generation tools helps users evaluate multiple design alternatives within a single model and quickly generate professional Engineering reports based on the optimum solution..

Design and Productivity tools include fully integrated concrete and steel design modules, BIM/DXF integration, 3rd Party data import links, and a comprehensive results validation and visualization tool. Add only the individual design components needed for your solution.

Available in three editions: Standard, Professional and Enterprise. Licensing options include Standalone installation, Networked installations or Subscription licensing.

New for Release 2017

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
Converting members to panels automatically converts point moments to equivalent shell loads
Convert joints to equivalent shell models to facilitate moment connection modeling with and without stiffeners
Member end connectivity (pinned, partially fixed, hysteresis, etc.) can be optionally be preserved when converting to equivalent shell models
Resulting Pier forces diagrams are relative to the original member element coordinate system
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
Mesh Generation Improvements
Mesh generators automatically identify and correct for multiple layers of overlapping panels, preventing duplicate mesh panels
Improved meshing for areas having meshable panels with embedded panel holes that share edges
Other Modeling Improvements
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.
