Microstran

Leading-edge Software for Structural Engineers

Microstran is a powerful general purpose structural analysis package with built-in steel member and connection design. Microstran features powerful modeling commands, a number of commonly used analysis methods, exceptionally fast solvers, and interoperability with a number of other engineering file formats.

Modeling Features:

Microstran offers a myriad of ways to efficiently model a structure. A host of time-saving modeling commands within the graphic interface help the user rapidly construct the Microstran model. Alternatively, using the standard structure wizard users can quickly create common structures such as portal frames, grillages, 3D frames, and continuous beams. Microstran can also import 3D CAD files to be used as the basis for creating models. Users can also create and modify the structure using the tabular input window within Microstran.

Analysis Features:

Microstran showcases a number of common analysis methods including linear and non-linear static analysis, elastic critical load, modes of vibration, and response spectrum. Automatic profile optimization facilitates exceptionally fast analysis. Special nonlinear elements including tension-only and compression-only members, gap and fuse members, and catenary cable elements provide flexibility in the types of structures that can be modeled. Microstran also enables other important analysis considerations including rigid member offsets, temperature effects, prescribed displacements, semi-rigid connections, and moving loads.

Integrated Steel Member and Connection Design:

Microstran offers design of members to a number of steel design codes including AS 3990, AS 4100, NZS 3404, AS/NZS 4600, BS 5950, AISC ASD Ed. 9, and SSCJ/ AIJ. Microstran performs design checks for beams, columns, and braces, according to the selected design code. Steel connection design is an extension of the steel member design option. After selecting the connection type at any location, design data and actions are automatically transferred to a new window where the user can interactively design the connection. Many connection types are available, including shear and moment connections, base plates, and hollow section truss connections.

Section Library Manager:

The Section Library Manager helps organize section data, including adding new and revising existing sections. Sections from different sources can be moved between different libraries. The properties of any section in the destination library can be viewed, re-computed, or checked.
