FRAME2Dexpress is a program for static and dynamic analysis of 2-dimensional framed structures. Distributed or nodal dead and live loads can be specified. Load combination is used according to Eurocode 1, with user defined load combination coefficients. The program performs computation of internal forces and diagrams for displacements, bending moments, shear and axial forces. In the dynamic analysis the eigenfrequencies and the mode shapes are computed. Graphical output for the diagrams and mode shapes is displayed.

Floating marinas, floating breakwaters and floating bridges are long structures made up of pontoons which are connected between them rigidly or with flexible connectors, and they are anchored at the bottom of the sea with mooring lines. They are usually placed in protected water regions. The waves in these regions are short crested waves. The dynamic analysis of long floating structures in short crested waves must take into account the special characteristics of the short crested wave loading, and the frequency depended load correlation along the structure.

The structural modelling using finite element methods does not present any difficulties. However the part of the analysis which presents special problems is the modelling of the loading in a short-crested sea. General purpose finite element programs do not provide methods for calculating the loading in a stochastic, short crested sea, and additional routines should be included in order to do the job. In conclusion the use of general purpose finite element programs is - time consuming, uneconomic, and susceptible to errors.

The program cgFLOAT has been developed especially for long floating structures in short crested sea loading. The dynamic response can be calculated via a frequency or time domain analysis. Theories and methods for hydrodynamic loading, short-crested waves, directional wave spectra, sea state simulation, and stochastic dynamics are included in the calculation routines. The computer code has been optimized taking into account the special characteristics of the structure and the loading. For the response calculation a Monte-Carlo simulation is used. This method is considered to be more advantageous over the usual frequency domain analysis, which is the only alternative, because it reduces the computational cost considerably and can be used for frequency and time domain analysis. It is based in simulating sets of nodal load series and calculates the structural response by deterministic dynamic analysis in frequency or time domain. The expected response values are obtained in the end by calculating the ensemble statistics between the simulated cases. The basis for computing the sets of nodal load series is the wave coherence along the structure, which is obtained from the directional wave spectrum.

WOODexpress. Structural Timber design software. A program for design and dimensioning of timber components, and timber roofs according to Eurocode 5 (EC5). In a graphic environment you design roof trusses and elements of timber structures. WOODexpress simplifies all the repetitive and time-consuming every day calculations for timber elements and timber roofs. Detailed report with calculations, automatic generation of truss drawings and details of connections.

To design a timber component or truss, choose from ready roof models, specify the main dimensions, loads, design code parameters, and the design is immediately performed and drawings produced automatically. Default values and checks for erroneous input values, facilitate the input data process. The report, which is created simultaneously, shows in detail all the calculations and the design steps with references to the corresponding design code paragraphs. Clear warnings informs you in case of inadequate design.

The material properties, the loads and the design code parameters, timber sections, can be adjusted by the user according to the requirements of the National application document. A context-sensitive Help system, guides you through the use of the program and the Eurocode provisions. On-line user's manual and frequently asked questions (F.A.Q.) are included in the program.

RUNET software FEDRA version 10.10/2012

The program FEDRA is an efficient tool for a complete design of masonry buildings, according to Eurocode 6. The masonry design is based on finite element analysis of each wall. The concrete floors and columns are designed according to Eurocode 2, and the timber roofs according to Eurocode 5. The seismic loads are defined as static horizontal loads, with a reverse triangular distribution. The building is defined with a drawing package included in the program. The building topology, load transferring, finite element modelling and dimensioning are automatically performed.
