SCADA Pro Timber +
Unified application of static and dynamic analysis and design of wooden structures
SCADA Pro Timber is a complete and comprehensive application for static and dynamic analysis and design of Timber structures according to Eurocodes and most European National Annexes.
It consists of the basic suite (SCADA Pro Analysis) and the additional tool about the design of timber structures according to EC5.
A rich library of typical cross sections and ready to use templates is provided. It also includes the production of the full report of the project.
New interface for even more flexibility and productivity
Invest and learn a single application that will meet all your needs for the analysis and design of any structural project with different materials.
SCADA Pro, based on Microsoft Ribbon technology, offers a unified, innovative and beautiful user interface, where it is easier to use more commands in a fully customizable environment.
Ribbons allow for visual layout and grouping of the commands in order to enable the user to discover and use the application’s tools easier, faster, and more efficiently.
On the left side of the interface, all the structure entities are shown in a tree form, categorized either per storey (level) or for the entire structure. This categorization helps in tracking any member of the structure by just selecting it on the tree which displays it in different color on the structural model.
The member’s storey is, then, isolated, and on the right side of the interface its properties are shown, with live editing capability. This process can be applied interactively, that is the member can be selected graphically on the structural model and this member’s properties will appear on the right side of the interface.
Additionally, a list of optional commands can be applied on each tree member selected. The optional context sensitive menu appears when right clicking, to help the user find features fast.
Automatic recognition of structural elements and creation of the structure from DXF, DWG file.
SCADA Pro, beautiful and productive interface offers automatic recognition of physical cross-sections from any architectural drawing in DXF or DWG form.
Recognition and modelling using the cross-sections of the SCADA Pro library can be applied selectively or automatically per storey, per structural member (Columns, Beams, Strip Foundations, Footings) or for the entire structure.
Furthermore, the structure’s slabs are identified automatically, as well as all cantilevers drawn in simple lines.
Full compatibility between AutoCAD Revit Structure Suite and SCADA Pro
AutoCAD Revit Structure Suite includes a complete set of applications for the structural model generation.
Bidirectional communication with SCADA Pro offers an easy way to import, through ifc files, 3D architectural models ready for analysis.
All structural members, columns, beams etc. as well as the loads and steel connections, automatically and accurately are converted to their respective structural elements of SCADA Pro.
Bidirectional communication between architectural and structural models ensures time savings and cost reduction.
SCADA Pro has been certified by Autodesk for the automatic, bidirectional communication interface with Revit Structure.
New powerful mesh generator of 3D surface finite elements
A new mesh generator of 3D surface finite elements is included in SCADA Pro.
Surfaces of any shape may be modelled and the meshing is completed regardless the pattern of holes or concentration points on a surface.
The mesh generation is automatic even when both surface and linear elements are present (nodes of neighboring linear and surface elements are automatically merged together).
The ability of inserting a point for adaptation of the mesh around it is also available.
The program also allows the insertion of a hole in an already meshed surface.
Any type of material may be attributed to a mesh with no problem.
Contours concerning the stress resultants, the strains or the computed reinforcement percentage “As” may be drawn on the produced mesh.
All load types are supported, e.g. uniformly distributed forces, concentrated forces, nodal forces, torsional moments, settlement, thermal actions etc.
Loading and combinations required by EC 0 are automatically calculated, with full editing options for the user.
Automatic generation of wind and snow loads according to EC1, as well as automatic attribution to the members with respective generation of load cases, ready for analysis.
The identifications of the slabs in SCADA Pro is accomplished automatically by the automatic assignment of the support conditions.
Slabs of any shape and any type are considered (Conventional, Zoellner, Sandwich).
There is also available the feature of converting a conventional slab to a slab simulated with finite surface elements.
The minimum thickness of the slab is calculated automatically applying the slenderness control.
The loads on the slabs can be imported in total for all slabs or selectively with instant processing and modification.
The loads can be imported as linear or in segments.
The assignment of loads is done with a single click on the columns and the footing beams with corresponding appearance of leakage lines and influence surfaces per structural member.
The loads on members are calculated through Marcus coefficient method according to the slab’s support conditions.
Fast and reliable solvers so that the user can rely on
SCADA Pro incorporates more than 30 years of know-how from ACE-Hellas advanced research and development team. It utilizes the most powerful solvers for all analysis methods and is using advanced parallel processing components to minimize execution time.
The following analysis methods are included:
Linear Simplified Spectral Method (Equivalent Spectral Method)
The linear simplified spectral method refers to the calculation of the displacements, deformations and the internal forces of the structure under static loads.
The calculation of the response is carried out by solving the linear system of equations which describes the model of the structure.
The externally imposed loads can be point on the nodes or distributed along the members, while the self-weight of the structure is taken into account.
The results of the linear static method can be used for the design of the structure, using the parameters provided by each regulation.
Linear Dynamic Spectral Method
The linear dynamic spectral method is a simplified approximate analysis method, which uses superposition of the eigenmodes for the estimation of the maximum response of the structure, under earthquake excitation.
Using this methodology the complete calculation of the response time histories, required in dynamic analyses, is avoided. Instead, the spectral values of the response which correspond to each eigenmode are calculated.
The value of the maximum response is next estimated using statistical analysis, since the maximum response of each eigenmode does not occur on the same time, but also the exact time is not known.
The great advantage of the spectral dynamic method is the fact that it requires a reduced amount of eigenmodes for the estimation of the structure’s response and therefore reduced computational cost.
Linear Dynamic Time History Analysis
Time history dynamic analysis refers to the calculation of the structure’s response under a predefined external load which varies in time (earthquake excitation).
Time history dynamic analysis is divided into linear and nonlinear.
It is considered as linear when all the structural members behave elastically and therefore the structure responds linearly to the imposed loads.
For the calculation of the response, the structural equations of motion have to be solved.
This can be done in two ways: modal analysis or direct integration of the equations of motion.
As far as the modal analysis is concerned, a reduced amount of eigenmodes that contribute to the response are chosen.
Normally, a quite small amount of eigenmodes with respect to the total degrees of freedom of the model, can lead to a satisfactory estimation of the time history response.
This leads to an important decrease of the computational cost.
As far as the direct integration method is concerned, the full mass, damping and stiffness matrices are used at the equations of motion, which are numerically integrated with respect to time.
The computational cost increases, but the solution obtained is exact and not approximate.
Non-Linear Dynamic Time History Analysis
Non-linear dynamic time history analysis is the most reliable methodology of the seismic behavior of structures.
For this analysis, models of the non-linear behavior of the structure’s materials are used, in order to properly simulate their fully inelastic and hysteretic behavior.
In order to estimate the structure’s response under seismic excitation, numerical integration of the equations of motion is required in time domain.
This type of analysis has high computational cost, but it is the only one that has the ability of estimating the inelastic deformations and internal forces under predefined earthquake loadings.
Due to its high accuracy, non-linear dynamic analysis can be used at every structure without limitations. But the response of the structure can present high sensitivity at the characteristics of each Imposed earthquake excitation.
For this reason it is recommended to repeat the analysis using more than one seismic events.
EC8 recommends that if less than seven seismic events have been analyzed, the user has to use the unfavorable scenario for the design of the structure, while in different cases the mean values of the response can be taken into account.
Multithreading CPU – GPU accelerated analysis
Analysis time of large models can take up to many hours or even days using traditional finite element and linear system technics. High Performance Computing (HPC) features can be used in order to reduce run times and efficiently solve large problems fast.
Analysis on multicore CPU or GPU
Run time can be reduced significantly by taking advantage of parallel solvers which run on multicore CPUs (Shared Memory Parallelism).
The solver divides the work into parts and each core (thread) takes over only one part, therefore solving the problem in parallel significantly faster.
For even better results, the graphics processor of a system can be used (such as an NVidia or AMD graphics card).
The main difference is that in multicore CPUs there are typically 2-8 threads, whereas in GPUs there are a few hundreds or even thousands of parallel threads.
This vast parallelism (fine-grained) leads to even lower analysis times for very large models.
