CDM Dolmen

DOLMEN PREFABBRICAZIONE is a software package for the design of precast structures.‎ IS TraveCAP allows the analysis of isostatic prestressed concrete beams with partial or full prestressing and the possible concreting.‎ IS TraveCAP exports the beam section and stresses to IS Fire, which performs the fire resistance verification.‎ IS Bracket is dedicated to the calculation of single or double squat brackets according to EC 2.‎ IS TraveCAP analyses isostatic prestressed concrete beams with partial or full prestressing and possible integration of in-situ casting.‎ The beam may have sections of any shape, symmetrical or non-symmetrical development, a flat or sloping soffit and extrados.‎ The programme considers all of the beam's 'life' phases and for each one carries out the verifications required by the most recent standards, at the ultimate limit state and at the service limit states.‎ IS Fuoco is the software for the design and verification of sections in fire conditions that can be composed of one or more outlines and have holes and internal cavities.‎ The parts that make up the section can be made of different materials and be variously exposed to fire.‎ The types of exposure available are Standard Fire, External Fire, Hydrocarbon, Internal Voids and Air 20°; the user also has the option of entering his own temperature-time curves.‎ PROPERTIES OF THE SOFTWARE PACKAGE IS TraveCAP IS TraveCAP is the indispensable software for designing isostatic prestressed concrete beams with partial or total prestressing and possible integration of in-situ casting.‎ The verifications are carried out at the ultimate limit states and continuously updated according to the most recent Standards, in particular according to NTC 2018.‎ The beam under study can have sections of any shape, drawn from a large database of standard sections, or defined by points or imported from dxf files.‎ The beam can have a non-symmetrical development, a flat or sloping intrados and extrados with sections and heights that vary along the axis with continuity or in a punctual manner.‎ Along the development of the beam, the slow reinforcement and prestressing reinforcement can be defined (which can also be imported from dxf), specifying the number of adhering cables.‎ The cable can be chosen from a large catalogue including the most common types on the market and can be fully customised by the user.‎ The entire geometry of the girder and the position of the cables can be imported directly from .‎dxf files.‎ The self-weight of the girder and any supplementary casting are calculated automatically.‎ Concentrated or distributed, uniform or trapezoidal loads and concentrated torques can be entered for each load condition.‎ The management of the execution steps, conditions and load cases is fully automatic, leaving the possibility of user intervention.‎ The calculation of tension loss due to relaxation and shrinkage is also performed automatically by the software.‎ The programme considers all the different phases of the "life" of the beam with the relative characteristics of the materials, and for each phase it performs all the verifications required by the standard, both at the ultimate limit state and at the service limit states, in simple bending or in deflection.‎ It is possible to view the beam created in 3 dimensions.‎ IS TraveCAP exports the section and its stresses to the IS Fuoco programme, which performs REI verifications of elements variously exposed to fire.‎ IS Fuoco IS Fuoco is the versatile and comprehensive software for the design and verification of sections under fire conditions.‎ The thermal analysis is carried out using the Finite Element method and requires integration over the entire domain and over time of the Fourier equation.‎ The section can be taken from a large database of standard shapes or from the profile of steel elements, or can be imported from .‎dxf or drawn using the programme's internal cad.‎ The contours introduced can be made of different materials, structural or otherwise.‎ The mechanical and thermal characteristics of the most commonly used materials are already present by default in the programme; however, the user can insert new materials by introducing the respective temperature-time and stress-strain curves.‎ There are several types of exposure available, defined by the standard, including Standard Fire, but the user can create his own types of exposure.‎ Once the exposure zones have been introduced and the mesh constructed, it is possible to generate heat maps at set time intervals.‎ At the end of the thermal calculation, it is possible to request the value of the temperature at any point within the section and the temperature of the gases in contact with the walls.‎ The mechanical verification of the stressed section is carried out in deviated press-flexion, with the possibility of introducing impressed deformations, to allow the analysis of composite sections, or with prestressing cables.‎ The mechanical verifications include the search for the deformation and tension situation according to a given stress tern and on the basis of stored heat maps; it is also possible to search for the ultimate stress.‎ IS DiagInt is a software application capable of receiving and displaying, in the form of an interaction diagram, the resistant domains of a generic structural section and the stresses acting on it; the programme extrapolates the results of IS Fire, obtained for different temperatures.‎ IS CarInc is a software application that performs fire load calculations in accordance with the Decree of 9 March 2007.‎ IS CarInc automatically takes into account all the coefficients foreseen by the Standard and derives the fire load and the fire resistance class required to guarantee the performance level.‎ IS FuocTab implements the analytical procedure for assessing the fire resistance of reinforced, normal and prestressed concrete construction elements dictated by EN 1992-1-2.‎ The values obtained refer to the most commonly used construction types and materials.‎ IS Shelf IS Shelf is the software dedicated to the analysis of squat shelves according to Eurocode 2, version UNI EN 1992-1-1:2005.‎ Data can be input either numerically or graphically, or by importing them from a structural file generated by 3D CAD Structure.‎ It is possible to define the type of bracket (single or double), the geometry and the pairs of acting forces in real time.‎ The typological characteristics of the reinforcements present are defined, in particular the main irons, the horizontal stirrups and the presence or absence of vertical stirrups.‎ To avoid trial and error, one can use the "Propose" function which, given the minimum and maximum values of the reinforcement, refines the calculation to find the optimal solution.‎ Using the "Complete Verification" command, the programme performs the necessary verifications for each load pair and reports them on the main drawing, divided into "relevance labels".‎ The results can be queried and the tensile and compressive stress values can be read off.‎ The programme is equipped with a 3D viewer for a visual check of the arrangement and size of the reinforcement.‎ IS Fire, IS BeamCAP and IS Brace create a complete and detailed calculation report in HTML (.‎html), Word® (.‎doc) or text (.‎txt) format.‎
