Comprehensive section property data is provided as well as tables of member resistances, which are given for grades S and S This enables rapid selection of steel members in compression , bending and tension. Tables are also provided for combined bending and compression , web resistance and shear resistance. It also provides: Section property data for: hot rolled open sections such as beams, columns, channels and angles; and hollow sections. Resistances for ordinary non pre-loaded bolts, pre-loaded bolts and welds.
An interactive version of the "Blue Book" is also available that includes design information in accordance with the relevant parts of both the Eurocodes and BS Produced by the SCI on behalf of Steel for Life, this comprehensive web-hosted eBlue Book covers the full range of both open sections and hollow sections both hot finished and cold formed , and will not require any software to be installed on the host computer.
Comprehensive design data is also provided for bolts and welds, rolling tolerances are given, and there are comprehensive sets of explanatory notes for both the Eurocodes and BS data. The user must select the steel grade , member type, section type and buckling length. The lateral torsional buckling resistance is calculated using the lateral torsional buckling curves for rolled sections. The user must select the steel grade , member type, section type, buckling length and choose the shape of the bending moment diagram by selecting an appropriate C1 factor.
The scope excludes the verification of class 4 sections. The user must select the steel grade , member type, section size and column length. The tool provides the opportunity to input an axial force from above , and the design values of the reactions on each face of the column at both ends of the column - these reactions are used to calculate the bending moments in the major and minor axis. The calculated interaction between bending and axial compression is verified against BS EN  Expression 6.
Identical lengths for major axis buckling, minor axis buckling and lateral torsional buckling are taken. The scope of this tool excludes the verification of class 4 sections. The user must select the steel grade , member type, section type, buckling length and provide the axial compression as well as the maximum and minimum values of major and minor bending moments Combined Axial Compression and Bending Resistance - UKB and UKC [ top ]Resistance of beams at elevated temperature This design software calculates the critical temperature of a beam UKB exposed to fire.
The software also calculates the time to failure when the beam is unprotected. This software is valid only for restrained beams carrying non-composite precast planks or shallow steel deck floors.
The user must select the steel grade , the beam, the loading, the imposed load category and the protection applied. The software assumes that the load on the beam is uniformly distributed.
Resistance of Beams at Elevated Temperature [ top ]Resistance of columns at elevated temperature This design software calculates the critical temperature of a column UKC exposed to fire. The software also calculates the time to failure when the column is unprotected.
This software only covers columns in braced frames. The user must select the steel grade , the column, the loading and the imposed load category. The user must also select whether the column is at the top storey or an intermediate storey. Resistance of Columns at Elevated Temperature [ top ]Composite Beam Checking Tool This design software carries out the design of simply supported composite beams to the Eurocodes. It is applicable to secondary beams subject to uniformly distributed loading, or primary beams loaded at midspan or third points.
The slab is constructed with metal deck , which may be selected from the ComFlor range, or specified for other metal decks. All standards are as implemented by the UK National Annexes   . At the execution stage the secondary beam compression flange is assumed to be fully restrained by the metal deck , and the primary beam compression flange is assumed to be restrained at load application points.
Verification of the beam at elevated temperature is carried out to BS EN . The beam may be unprotected or protected; a range of protection types and thicknesses may be selected. If the beam is unprotected, the software reports the time to failure, which may be compared to the required period of fire resistance. If the beam is protected, two results are provided: the critical temperature, which may be used to specify the required performance from any protection system.
Composite Beam Checking Tool [ top ]Elastic Critical Moment for Lateral Torsional Buckling This design software calculates the elastic critical buckling moment for lateral-torsional buckling Mcr , and the elastic critical load for buckling Ncr. The scope of the tool includes standard UB and UC sections. Sections may also be defined by dimension, or by property, so the tool can be used to assess fabricated members. The cross section height can also vary linearly along the beam.
A wide range of supports, restraints and loading conditions can be specified. Supports and restraints can be specified at any location along the beam and at a distance from the shear centre, with variable stiffness values. Point, moment and trapezoidal distributed loads can be specified at any location along the beam, and at a distance from the shear centre, to assess destabilising and stabilising loading conditions.
Files may be saved and subsequently uploaded from local storage. The calculations are performed for a single vertical bracing system, which is assumed to be a vertical Pratt truss. From the user-defined characteristic permanent and variable actions, and the floor area associated with the bracing system at each level, the software calculates the EHF.
The characteristic wind load per bracing system is assumed to be uniform over the full height of the bracing system; it is converted to point loads at floor levels in proportion to the storey heights. Two cases are verified, firstly with imposed load as the leading variable action and secondly with the wind as the leading variable action.
In addition to selecting the column and the grade of concrete, the user must select the size, thickness and steel grade of the base plate. Base Plate Designer [ top ]End plate designer This design software calculates the vertical shear resistance and tying resistance of partial depth and full depth end plate connections on beams UKB.
Selecting the steel grade and beam size generates a set of parameters for a typical standard end plate connection. These parameters number of bolt rows, pitch, offset, edge distances, gauge, plate width and thickness may subsequently be changed and the resistances re-calculated.
At any stage, re-selecting the beam will generate the typical connection. End Plate Designer [ top ]Fin plate designer This design software calculates the vertical shear resistance and tying resistance of fin plate connections on beams UKB.
Selecting the steel grade and beam size generates a set of parameters for a typical standard fin plate connection. These parameters number of bolt rows, pitch, offset, edge distances, gauge, and plate thickness may subsequently be changed and the resistances re-calculated.
Fin Plate Designer [ top ]Gusset plate designer This design software may be used to verify the resistance of lapped gusset plate connections subject to compression, typically used where diagonal bracing connects to other members. The gusset plate may be supported on one edge only sometimes used for lightly loaded roof bracing or on two edges, which is the common case where vertical bracing intersects at a beam-to-column connection.
The design model assumes that the unsupported end of the connection is free to displace laterally, as the bracing member buckles. The eccentricity between the two lapped plates is accounted for in the design model. The resistance of the connection is based on a yield line analysis, with the moment due to eccentricity distributed to the two plates in proportion to their stiffness.
The design model has been validated against tests and Finite Element Analysis for orthodox connections with maximum 20 mm plates, M20 grade 8. Gusset Plate Designer [ top ]Floor response calculator This design software allows designers to make an immediate assessment of the dynamic response of a floor solution. The software may be used to examine complete floor plans or part floor plans, comparing alternative beam arrangements.
The software reports the results of approximately 19, arrangements of floor grid , loading and bay size, which have been investigated using finite element analysis. The designer must select between a variable action of 2. The designer must also select the arrangement of secondary and primary beams, with typical spans, which depend on the arrangement of the beams. Secondary beams may be placed at mid-span or third points.
When a decking profile is selected from the ComFlor range, an appropriate range of slab depths are then available to be selected. Generally, thicker slabs will produce a lower response factor. When selecting the slab depth, solutions which result in a response factor higher than 8 the limit for a typical office are highlighted.
The primary and secondary beams are selected automatically from the range of Beams UKB in grade S as the lightest sections which satisfy strength and deflection requirements; these cannot be changed by the user.
The selection of the lightest sections is made to produce the most conservative dynamic response , as stiffer beams will reduce the response. A visual plot of the response is also provided for both the steady state and transient response. Hovering over the plot shows the response factor.
Generally the higher response will be in an end bay, where there is no continuity. The fundamental frequency of the floor is presented on the output screen. If the actual design differs from the pre-set solutions in the tool, users should note the following: Using stiffer beams will reduce the response Using thicker slabs, and stiffer beams, will reduce the response The gauge of the metal decking has no significant impact on the response factor Voids that break the continuity of beam lines will lead to higher response factors Floor response calculator [ top ]Carbon footprint tool for buildings This web tool enables designers of multi-storey buildings to easily estimate the embodied carbon footprint of the superstructure.
There are two ways to use the tool. Whichever mode is used, appropriate carbon emission factors are then applied to the material quantities to estimate the overall carbon footprint of the building. The results are presented as a single CO2e figure for the building, a CO2e figure per m2 of floor area, and a bar chart illustrating the contributions to the total made by the various elements of the building, i. Roofs may be flat, monopitch or duopitch. Orography is assumed to be not significant.
The user must define the dimensions of the building and provide sufficient geographic data for the evaluation of peak velocity pressure.
Tata Steel and University of Manchester have developed an excel plugin software package called FireSoft that will design a concrete filled hollow section column according to these provisions for fire periods up to 2 hours. It is also suitable for ambient temperature design The guidance, and therefore FireSoft, is applicable to hot finished structural hollow sections of fine grain steel BS EN   and does not apply to cold formed hollow sections.
The guidance and software is applicable to simple construction only. Flooring choices include shallow floors , downstand composite and light steel systems and users can select from a range of floor treatments above and ceiling options below the structural elements. Wall forms involving single or twin studs , with or without acoustic quilting and a range of different boarding options can be selected for analysis.
The values predicted by this tool are only intended to be used for preliminary design purposes because there are many other factors besides specification of the wall or floor format that will affect acoustic performance e.
It is consistent with the latest SCI guidance on composite highway bridge design , and the plate sizes were derived using the Eurocodes and relevant UK National Annexes. The scope includes simply supported and continuous plate girders for both multi-girder and ladder decks. The spreadsheet tool accounts for the differences between inner and outer girders, and provides both elastic and plastic designs.
It is accompanied by a helpful User Manual explaining exactly what the tool is, and how to use it. A series of design charts are also available to facilitate manual calculation if desired.
