Statics is a widely used software of linear static and dynamic analysis and also non linear static (push-over) analysis of multistorey buildings, forming appropriate space framesmodels (6 degrees of freedom per node). Structures could be of reinforced concrete, masonry, steel members, timber members, composite members, using EUROCODE 2 (design of concrete structures), EUROCODE 8 (design provisions for earthquake resistance of structures) and of course EC1, EC3, EC5, EC6 and EC7.

• Bearing structure can be of Reinforced Concrete, Steel, Timber, Masonry, Composite Steel and Concrete and combinations of the above materials.
• Codes : Eurocodes (1-8),
• Constants: parameters are fully specified automatically or by user’s own decision, in order to determine the design and calculation features (material properties, seismic parameters, soil properties, reinforcement rules).
• Designer can insert a formwork drawing file, in a .dxf format, from any architectural design program and automatically convert it to STATICS data file.

• Designer can also insert a drawing or an image as background (raster image) on which he/she can describe the structure’s formworks in order to form the space frame model.
• Very easy and fast graphical input of structural elements, in case there’s not an architectural drawing file, in any kind of plan shape.

• Very easy to modify, change, delete or add elements, members with automatic re -identification of the model.
• Fully automatic identification of slabs and slab analysis. One span beam can automatically be divided to multi-span beam in case it is crossed by columns, other beams or edges. Uniform floor loads distribution to frame members (beams)

• Special types of floor panels: steel, timber, composite steel and concrete.
• Columns may be designed as rectangular, circular, T, or L or U (core) shaped sections and as complex sections consisting of many rectangular parts.
• Designer can describe curved shaped columns/walls sections, curved shaped in plan beams, curved edges (the outlines of cantilevers, of slab holes).
• Designer can describe height-wise inclined columns. Column cross-section dimensions can differ from storey to storey if the designer wants to.

• Multiple pitched roofs on the same plan can be created (with various ridges, slopes, perimeter shapes).
• Special assumptions: hinges at beams or columns ends, modification of slabs or beams support conditions. Designer can impose some additional vertical or lateral loads to columns (besides those which are automatically calculated by the program)

• Special load cases automatically created:
  • Forces due to temperature changes (uniform temperature change to the whole structure or per storey level, difference of temperature between internal-external region of a member, capability to impose temperature changes to beams only or/and columns or/and footings.
  • Snow loading
  • Wind loading (lateral wind forces on structure’s surfaces, roof uplifting)
  • Earth pressures (static-seismic) to basement shear walls
  • Differential settlements

• Load cases combinations may be specified by the designer (besides those which are obligatory by the codes) in order to dimension the members of the structure.

• Space frame model
  • Structure is considered fixed in foundation level or on elastic supports
  • When a beam is eccentrically connected to walls, a rigid member is automatically created in order to model the eccentricity as a rigid connection
  • Diaphragmatic action is taken into consideration

• Various foundation types
  • Designer can describe individual footings (pads) or common footings (of 2 or 3 columns) with connecting beams between them
  • Strip footings and grid foundation (strip footings forming a grate)
  • Raft foundation (may occupy the entire foundation area or only a part of it)
  • Combinations of all the above foundation types

  

• Capability to describe foundation members at uneven levels

• A very fast and highly effective analysis and dimensioning is performed according to Eurocodes (1-8).
• Output results can be presented in detail(data, all required calculations by the codes, checks information, members dimensioning e.t.c)
• Results are displayed on screen and can be accessed through a program’s word processor
• Very detailed estimations of material quantities are computed: per storey level, per member kind (slabs, beams, columns, footings). A list of total length and weight of reinforcement is available.
• Formworks are automatically generated upon user’s request and can be displayed in a CAD environment (AUTOCAD is not required). User then, can process it (move, erase, insert text, add lines, add circles) in case he wants to. Of course formwork drawing files can also be produced in a .dxf format.
• In a formwork drawing file, tables with cross-section dimensions/reinforcement of columns, beams, slabs might also be displayed.

• There’s also the capability of drawing automatically a cross-section on a beam or along a specified direction of a storey and/or a building, even in cases of composite buildings (e.g. steel superstructure-concrete basement)

• Assessment and retrofitting of buildings – strengthening of buildings
  • Describe the existing bearing structure: cross-section dimensions, reinforcement, position of columns, beams, slabs, footings
  • Strengthening of buildings using concrete jackets
  • Strengthening of concrete structural members using CFRP materials (CFRP stands for Carbon Fiber Reinforced Polymer)
  • Import new structural members in contact with the old ones
  • Results presentation and formworks production, pointing distinctly the existing and the new structural members

• Steel structural members
  • Steel columns, steel beams, bracings
  • Beam-to-column connections (bolting, welding, gusset plate) and beam-to beam connection (shear connections
  • Anchoring steel columns to concrete footings or to concrete columns of underlying storey

  

  • Composite floor system using trapezoidal steel sheets
  • Steel beams composite with a slab
  • Composite steel columns encased in concrete

• Timber structural members
  • Design and dimensioning timber columns, timber beams according to EC5
  • Checking of timber floor panels

  

  • Connections between timber structural members or between timber structural members and steel structural members

  

  • Timber trusses

  

• Masonry: stonework, brick-wall, confined masonry structure.
• Dome: analysis and dimensioning of spherical and cylindrical shells can be performed in order to design concrete domes, silos, tanks etc.

Highlights on Eurocodes

• Automatic calculation of EC8 seismic parameters:
  • Calculations are performed taking into consideration geometry, tortional checks, the slenderness of the building in plan (aspect ratio), in order to determine whether a building is regular in plan and/or in elevation or not.
  • In wall, wall-equivalent dual or torsionally flexible systems the factor K_w=(1+α₀)/3 is automatically calculated.(In frame, frame-equivalent dual systems K_w=1)
  • Calculation of μ_φ, q_x, q_y, q_v
  • Graphical preview of the floor centre of the mass and the centre of lateral stiffness, circle of inertia (with radius Is), ellipse of torsional stiffness (with semi-axes r_x, r_y) and the marginal rectangular (0.3r_x, 0.3r_y).

  

  • Statics calculates automatically whether the infills are reduced from one storey to another (e.g. an open ground floor-Pilotis) and if that’s the case seismic internal forces in the columns are increased by the factor n.
  • Combinations of unfavorable loading cases

  

  

• Redistribution of bending moments in accordance with EN 1992-1 and 1998-1 &4.4.2.2

• Complete and analytic dimensioning and detailing according EC2, EC8 FOR DCM,DCH buildings:
  • Calculation of reinforcement ratios in beams.
  • Checking of bond along the beam bars crossing beam-column joints.
  • Capacity design of beam-column joints in flexure and automatic calculation of capacity design shear forces by computing ΣΜR_b and ΣΜR_c
  • Design envelope of bending moments and shear forces in concrete columns/walls.

  

  • Checking of shear reinforcement and confinement reinforcement in columns/walls.
  • Checking of beam-columns joints in shear for DCH buildings.

  

  • Checking of the effects of infills on columns (infill in contact to a part of column’s full height, or infills in contact to the one side of a column, or reduced infills along height of the building) by automatic identification of masonry infills in plan.

  

  

• Push Over Analysis
  • Exact calculation of the ratio α_u/a₁
  • Graphical preview of plastic hinges formation to space frame model of the evolution of damage.
