Custom identification of the plane starting from which to apply the seismic action even at different levels in the same structure
In the case of a partially underground configured building, EdiLus-RC allows you to define the Seismic Zero Plane or the plane starting from which to apply the seismic action without considering the seismic forces acting on the underground section.
With this method the seismic model will include the entire structure, while the masses below the seismic plane will be considered as null.
Representation in nodes
To calculate stresses correctly, the Analytical Model structural member connections between the various elements is shown schematically: EdiLus-RC is able so to obtain rigorous results, without the approximations deriving from less appropriate analytical schematizations.
Load combinations – “Snow Load” calculation
When addressing load analysis on floor slabs, balconies, floors, and vaults, EdiLus-RC automatically calculates the surface load due to the weight of snow.
Pressures on walls and additional loads
A revolutionary input feature allows you to define actions related to hydrostatic and soil pressure on the walls. In addition, specific objects allow the user to apply additional loads (concentrated forces, linear forces, surface forces, concentrated moments and linear moments) directly on the various structural elements (beams, columns, walls, floors, and foundation slabs).
Infinitely rigid floors
With EdiLus-RC you can also define the infinitely rigid behavior of the entire deck for each floor independently, in order to model the structure to its actual behavior as in the case of openings in the slabs, stair cases, split level floors, etc.
Defining custom sections and generic materials
EdiLus-RC allows you to define and add, in addition to a vast archive of predefined sections, your own custom sized profile sections for beams and columns of any shape by using specific editing tools. Each section can be assigned with the mechanical characteristics of a generic material different to the characteristics of generic reinforced concrete. This means that you can easily model, inside a reinforced concrete building, beams and pillars in steel, aluminium, wood or other material types.
A transparent pen allows the user to freely customize their own reinforcements defining diameters, lengths and rebar position as well as the rebar shapes. While rebar editing progresses, the reinforcement diagrams (bending, shear, torsion) are updated dynamically.
Choosing the rebar layout criterion
EdiLus-RC allows you to choose between different rebar arrangements some of which allow you to define reinforcements with maximum reduction at the support ends. The user, however, still has the maximum freedom to customize reinforcements.
Structural analysis of timber elements integrated in reinforced concrete structures
Roofs, porches, and other timber components present in a mixed reinforced concrete structure can be modelled and calculated in an integrated manner to the entire structure to obtain results and construction documents for the different materials and with a single input.
EdiLus-RC calculates solid and laminated wood through a quick and easy object-oriented modelling process. Items can only be one-dimensional (beams and pillars) with rectangular and circular section types.
Complex timber elements become simple
To the very simple elements, present in a structure, complex objects such as trusses, designed through effective parametric input, can also be added; a wizard lets you change the model, composition, geometry, sizes and all the relevant parameters that define a truss to respond to every need…
And all very quickly. A specific function automates inserting and connecting purlins: building up even a complex timber roof becomes extremely easy!
Calculating and connecting timber members
The various timber members are checked for bending, shear and instability also taking into account the possible inclination of stress actions in relation to the wood grain. Particular attention has been put into the design of wooden member connections. In the contact areas, the software proceeds to shape the members so as to define notches and support areas in great detail allowing the user to run a Contact Point Verification.
Existing reinforced concrete building verifications
The program allows you to schematize generic-strength materials and existing reinforcement to simulate structures built in different historical/legal contexts and guides the engineer to perform diagnostic tests on the structure in order to better understand its characteristics.
The checks immediately return the analysed structure’s degree of seismic vulnerability and help to understand the possible interventions necessary for seismic resistance upgrading. You can intuitively add new roofs, elevations, floors, etc., to the existing structure and then proceed to an overall verification.
The program also allows a graphical and numerical input to define measures for strengthening the building (jacket linings, plating, FRP grouting, etc.) with specific tests to evaluate the effects of such reinforcements.
Behaviour checks, conducted on the existing structure and the achieved structural improvements, can be simulated with in linear calculation mode.
Tools that allow the structural engineer to have a clear comparative framework between the current de-facto stage and the design stage with the proven evidence of increased global resistance.
Drawings, calculation reports and the structure’s bill of quantities, accompany the analysis of the structure and the improvement interventions.
Guide to the level of knowledge and the level of resistance of materials
EdiLus-RC helps the technician to build the safety factors to be used in the calculation by means of a guide to the knowledge of the structure and its materials. If we can gain a high level of knowledge of the used materials, reinforcements, load analysis, etc. the analytical model will be more likely to simulate reality and therefore more precautionary safety factors may be adopted. When the level of knowledge of the structure is low, the safety factors must be higher.
The user can directly indicate the level of knowledge of the structure to check or use a special wizard that, with an automatic user guided procedure, allows you to provide the software with all the geometry information, construction details, material properties or the data deriving from investigation and testing.
Based on the information provided, the program automatically identifies the level of knowledge.
Even for the definition of material resistance, EdiLus-RC offers a wizard for data input. You can indicate the type of conducted tests (for example, a core drilling or sclerometric testing) and the test results. Once the tests are characterized, you simply then need to select them as specified in the wizard to get the resistance calculation to be adopted in the following verification.
Reinforcement insertion and re-building
Inserting the existing reinforcements can be addressed in a quick and accurate manner using the EdiLus-RC rebars insertion mode; a powerful input procedure that includes typical “copy and paste” and “duplication” functions and with which you can easily copy the reinforcements used in a beam to any other beam or group of beams.
Verifying the current De-Facto stage
Once the structure’s characteristics are defined and calculated, the software offers various ways to control the results of the de-facto stage checking. Thanks to detailed result tables, collapse accelerations for each element and for each mechanism are provided so as to easily identify the most critical points of the structure.
Design and evaluation of interventions for improvements or adjustments
EdiLus-RC enables you to design interventions for improvement or adjustment in which you can apply both reinforcements on existing elements, and therefore referred to as “de facto”, or add new structural elements, therefore defined in the design phase, such as new columns, walls, shear walls, etc.
The structural engineer has the opportunity to choose the most appropriate type of intervention from a menu among which:
• FRP plating for Bending
• FRP plating for Shear
• Height increases
• Steel jacket linings
• FRP wrapping
• Node Confinement
• Reinforcement mortar for on Wall repairs
• Wall reinforcements with FRP
Thanks to automatic recalculation functions, structural improvement interventions prove to be simple and well focused on specific design aspects.
Once the calculations are completed, the engineer has all the elements to assess the effectiveness of the proposed intervention; the software automatically produces reinforcements for the new elements and, above all, a comparison report between the current de-fact stage and the design stage with reference to the risk indicator.
Detailed drawings and schedules of interventions and the relating cost estimate
In addition to performing all the necessary calculations in checking the de-fact stage and the evaluation of planned improvements and adjustments, EdiLus-RC automatically generates the construction documents too (calculation report, geotechnical report, vulnerability data, comparison reports, summary charts, frameworks, working drawings, calculation tables, etc.), together with the relating project cost estimate.
EdiLus-CA also supports:
- resistance tests and checks
- geotechnical testing and ground tensions (with the limit load calculation)
- automatic generation of beam sections with reinforcement schedules
- visualisation, for any selected structural element, of the local reference axes system
- insertion and management of seismic shear walls in accordance with all verification criteria and reinforcements required by law
- insertion, management and verification of slanted columns and deep beams
- calculation and design of reinforcements for stairs and balconies
- the development of envelope diagrams of the calculated stresses acting on the foundation beams (both for the bending moment and for shear) and the moments calculation for foundation slabs, specified according to direction (main and secondary) and side (upper and lower)
