It has a very smooth learning curve
Featuring an intuitive graphical environment with a series of input modules (tabs) and a very straightforward methodology from the materials definition to the performance criteria and the selected output, SeismoStruct is extremely easy to learn. Neither manuals, nor tutorial examples are required. Any engineer with just a limited knowledge of the Finite Elements procedures can open the program and start using it. Further, the Building Modeller and the Wizard facilities constitute two modules, with which a user can create on-the-fly reinforced concrete building models, by introducing just the geometric and reinforcement parameters of the structure.
It offers increased productivity
Particular emphasis has been put, so that the program is not only intuitive, but also easy and fast to use. With the Building Modeller facility, the model of a multi-storey reinforced concrete building can be created within minutes. Columns, beams, slabs and stairs are input with just some mouse clicks, large libraries of materials have been included (e.g. FRP wraps), and can be easily included in the model, whilst the applied loading is considered. Further, the execution of the chord rotation and shear capacity checks is done in a completely straightforward fashion, whereby the user may specify only the Standard, the limit state and the members to be checked, and the capacity at every step of the analysis is calculated and checked against the demand automatically by the program. All these facilities result in a very user-friendly environment, whereby the modelling and checking even of structures of high complexity is carried out effectively and quickly.
It offers enhanced accuracy
SeismoStruct, has been extensively used and verified by thousands of users for more than ten years. It employs the fibre approach to represent the cross-section behaviour, an approach that is generally more accurate, especially with non-ordinary sections. Moreover, the distributed plasticity force-based elements with the integration sections located along the length of the member are most suitable for large shear walls, where inelasticity occurs along their entire height and not just at their ends, something that is explicitly assumed by the programs that employ the plastic hinge approach.
The accuracy of the solver in the nonlinear analysis of framed structures is very well demonstrated by the numerous successes of SeismoStruct in recent Blind Test Prediction Exercises, such as the Concrete Column Blind Prediction Contest 2010 (UCSD, San Diego, USA), which was sponsored by the Network for Earthquake Engineering Simulation (NEES) and the Pacific Earthquake Engineering Research Center (PEER, Berkeley University), or the Blind Test Challenge of the 15th World Conference on Earthquake Engineering (LNEC, Lisbon, Portugal).
It provides improved stability
SeismoStruct possesses the ability to smartly subdivide the loading increment, whenever convergence problems arise, with the level of subdivision depending on the convergence difficulties encountered. When the convergence difficulties are overcome, the program automatically increases the loading increment back to its original value. In this way, the program achieves numerical stability and accuracy even at very high strain levels, enabling the precise determination of the collapse load of structures.
