TILT-UP WALL PANEL DESIGN (AS3600-2001)
Calculation to design a reinforced concrete tilt-up panel with up to two openings (doors or windows) in accordance with AS3600-2001 and ACI 318.
The panel is “check designed” for both the lifting sequence (assuming uncracked) and for in-position (assuming cracked) for relevant dead, live, wind and seismic loads. Vertical loads may be applied to the top of the clear height of the panel and may be located eccentric to the centreline thus inducing bending moments into the panel. Lateral wind or seismic loads may also be applied resulting in further bending moments.
Secondary bending moments resulting from P- effects are accounted for using section 14.8 of the US reinforced concrete code ACI 318.
The analysis of the lifting condition is calculated using a static deterministic method for a single or a two point lift. Design moments and shears are determined for any number of specified angles of lift.

CONCRETE SUB-FRAME ANALYSIS
These calculations consider a simplified sub-frame consisting only of a beam, the columns attached to the ends of the beam and the beams on either side.
The calculations firstly determine the geometry of the three spans (including area and second moment of area), the stiffness of the end beams is modelled by applying a stiffness factor to the second moment of area (the fixity of the beam remote ends determine the stiffness of the beams on either side of the central beam). The calculations use the sub-frame geometry and properties within the continuous beam analysis program, where the loads can be added in order to determine the design shear force and moment. These forces can then be optionally used in the RC beam design calculations, to design span 2 (the central beam).
The size and stiffness of the columns are translated into vertical and rotational spring stiffnesses for the supports used in the continuous beam. The moments generated in the supports are then used to determine the moments in the columns of the sub-frame.

RC COLUMN DESIGN (AS3600)
AS 3600 - Concrete structures.
These calculations work out the cross-section strength of reinforced concrete columns subject to combined axial force and bending moment.
The calculations focus on the detail of main (longitudinal) reinforcement. The reinforcement must consist of deformed bars with a rib geometry that provides adequate bond.
This calculation does not cover the calculation of design action effects, however, these effects calculated at critical sections need to be compared to the axial force and bending strengths determined using the methods in this calculation.
The design rules utilized are based on considerations of equilibrium and strain compatibility (plane sections remain plane after bending) to determine the load and moment strength.
The column cross sections are doubly symmetric.
The stress-strain curves for both the steel and concrete are assumed to be of a form defined by recognised simplified equations.
A simple rectangular stress block of 0.85f'c is used for the concrete at strength limit state subject to the limitations of clause 10.6.2 of AS 3600-2001, and the steel is assumed to be linear elastic-plastic in nature with a constant yield stress.
The calculation determines the four key points on the load-moment strength interaction diagram.

WALL STRIP FOOTING DESIGN (AS3600)
These calculations start from an applied load per metre run and an allowable bearing pressure, and determine the minimum foundation width required to keep the net bearing pressure below the permissible bearing pressure.
For mass concrete foundations, the calculations check that the spread of the load in the footing is >45 degrees and hence an un-reinforced solution is adequate.
For reinforced footings the calculations calculate the shear and moment at the face of the wall and calculate the minimum reinforcement required for the base.
The calculations require that the wall type (internal, party or cavity) is selected. This wall type is only relevant if a wall load chase down calculation has been run before this calculation. The correct loads will be picked up automatically in this instance if the same wall type is selected.

HIGHWAY ALIGNMENT HORIZONTAL CURVE DESIGN
Horizontal curve - These calculations design a circular horizontal curve (no transitions). The calculation uses a 'generic number of chords' method, which calculates the optimum chord length based on the criteria of the length of chord required to approximate the arc length of the curve.
Vertical curve - These calculations design a vertical curve and provide the setting out information (reduced levels at the relevant chainage points). This calculation can be phased with the horizontal curve design, to enable the same setting out points to be used.
For phasing of the horizontal and vertical curves, a reference point on the horizontal curve must be given. The chainage points are then calculated in relation to this reference point. The chord length (or frequency of levels) should also coincide with the chord length used in the horizontal alignment calculations. Where applicable the appropriate default values are given.

These calculations determine the wind speed and wind pressure in accordance with AS/NZS 1170.2.
The calculations provide wind pressures for ultimate and serviceability limit state. Shielding and topographic multipliers can be directly input or can be calculated.
One wind direction is considered for each run of the calculations. Hence up to four runs would be required to determine the worst suction and pressure loads on any particular wall or roof surface from all wind directions.
COLUMN LOAD CHASE DOWN (AS1170.1-2002)
AS 1170.1-2002 – Structural design actions. Part 1 – Permanent, imposed and other actions.
These calculations work out the factored axial loads on each stack of a multi-storey column due to permanent and imposed loading.
The calculations cover internal, edge, corner and re-entrant corner columns.
For each column type the floor is divided into quadrants. Each quadrant may have a different load and edge loads may be added to those quadrants forming the edge of the building.
Imposed loads can be adopted reduced in accordance with clause 3.4.2 of the code, or the full imposed loads can be applied with no reduction. Each individual quadrant can be selected to have imposed load reduction or not. The calculations always start with a roof where load reduction factor is 1.0, and for remaining floors below roof it is calculated.

COMPREHENSIVE WIND LOADING (1170.2)
These calculations determine the site wind speed, design wind speed and design wind pressure in accordance with AS/NZS 1170.2.
AS/NZS 1170.2 covers structures within the following criteria: (a) Buildings less than 200 m high. (b) Structures with roof spans less than 100 m. (c) Structures other than offshore structures, bridges and transmission towers.
The calculations provide wind pressures for ultimate and serviceability limit state. Wind speed multipliers can be calculated and applied to cater for shielding and topographic conditions (these can be entered directly or can be calculated).
The site wind speeds are determined for each cardinal direction. The design wind speeds are determined for each building orthogonal axes considering the maximum site wind speed in the range +/- 45 degrees for each orthogonal direction. The design wind pressures are calculated from the design wind speeds for each orthogonal direction.
In this calculation only one value can be used for the terrain category for the site and no change in terrain category can be calculated. The user can select Mzcat from a table (as per AS/NZ 1170.2) or can choose to specify any value.
Aerodynamic shape factors can be calculated for enclosed rectangular buildings in accordance with AS/NZS 1170.2 Section 5.
No local pressure effect (Kl) has been included when determining the aerodynamic shape factor and this should be considered separately. No consideration or reduction has been made for permeable cladding (Kp) in the shape factor calculations.
Frictional drag forces have not been included.

HIPPED END LOADING
These calculations determine the loading on the gable frame, flat top portal and first portal frame resulting from a hip extending over two frame centres.
It is assumed that the flat top portal gives no support to the hip raker. This introduces a small error local to the intersection of the flat top portal and the hip raker. All loads from the raker do pass to the flat top via the local jack rafters.

NOTIONAL LOAD CHASE DOWN (AS4100-1998)
These calculations work out the notional horizontal loads at the roof and each floor level of a multi-storey building.
The floor area and perimeter wall lengths can be calculated for a range of building shapes, or values for these parameters can be entered directly, by selecting the user-defined shape option.
SEISMIC LOADS (AS1170.4-2007)
This calculation determines earthquake actions on building structures as detailed in AS 1170.4-2007 Part 4: Earthquake actions in Australia.

WALL LOAD CHASE DOWN (AS1170.1-2002)
These calculations determine the strength and service design actions on the foundations under the walls in consideration for a multi-storey building, based on the loading from the floors either side of the wall on each level and the self weight of the wall.
These calculations also calculate the wall design load at each level of the building, again based on the loading from the floors above the wall on each level and the self weight of the wall. The total load includes the whole self weight of the wall on the level at which it is being considered.
The permanent loads are built up from the separate elements of each area, such as the roof, including sensible default values e.g. under roof loading the total dead load is built up from Tiles, Battens, Felt and Rafters etc., all of which have default values but which can changed to suit.
The walls types that can be considered are party, internal or cavity walls.
The roof can be timber or steel and sloping or flat. Each floor can be timber, in-situ or precast concrete.

RETAINING WALLS RETAINING WALL ANALYSIS & DESIGN (AS4678-2002)
The calculations check the stability of a retaining wall which may feature a sloped or stepped back or face with or without a downstand, either propped or unpropped, against sliding and determines the maximum and minimum base pressures beneath the wall.
The reinforced concrete design calculations allow the design of the retaining wall toe, heel, downstand and stem for bending and shear as appropriate.
Soil and surcharge pressures acting on the wall can be calculated using either the Coulomb or Rankine theory. In addition the calculation allows for water pressure behind the wall if appropriate.
The calculations use the following Codes of Practice, as appropriate:

SECTION PROPERTIES COMPOUND SECTION PROPERTIES
These calculations determine the section properties of one of three possible combined section shapes, two I sections (at 90 degs), a channel on an I section or a plate on an I section.
Refer to the „Explanation of this set‟ for more detail.
SECTION PROPERTIES CALCULATOR
The Section Properties Calculator calculates section properties for a section constructed from rectangles, triangles and circles, with or without holes.
The calculated section properties are returned to the TEDDS document as variables for use in further calculations.
Standard section types can be designed quickly from within the calculation user interface by specifying the dimensions of the section.
Custom sections can be created by using the Section Designer application. This application allows a section to be designed using a simple CAD style user interface. Sections can be saved for re-use at a later date.
Existing datalists can be used to import sections either as a starting point for new sections or to create combined sections (such as a channel on an I section). Datalists are available for the UK, USA, Canada, Japan, Singapore and Australian sections.

STEEL BEAM ANALYSIS & DESIGN (AS4100)
From Australian Standard AS4100: Steel structures.
These calculations check the design of rolled and welded I and H sections, rolled channel sections, rolled T sections, rolled rectangular hollow sections and rolled circular hollow sections subject to major axis bending, shear and axial tension or compression.
The design and analysis calculation is fully integrated with the TEDDS continuous beam analysis module allowing analysis of beams of up to 10 spans with up to 20 loads per span, 20 loads per support, 8 different load cases and 20 load combinations.
The beam section is designed for worst case applied moment, shear, compression or tension and deflection across all beam spans.
The design only calculation allows you to design a single section based on defined values for bending moment, axial compression or tension, and shear force.
