Wind Loads beyond scope for multi-span frame with roof slope less than 5 degrees

According to BS6399-2, rafters slopes less than 5 degrees should be treated a flat. For a single standard span Tekla Portal Frame Designer will apply the adjacent, intermediate and remote coefficients assuming a single flat roof. For multiple spans it will not. You need to calculate the coefficients & their lengths and apply them manually. As the scaling length is likely to be based on the eaves height, you could create a single span frame (does not need to be the full width of the building) and generate the wind loads cases to obtain this information. In the main model, the first frame

What is the difference between ULS Wind and SLS Wind?

ULS Wind uses coefficients from BS6399:2 Table 5 and should be used for all strength checks.SLS Wind uses coefficients from BS6399:2 Table 5A and can be used for serviceability checks. If you wish to use SLS wind (Table 5A) you should create a combination with ULS wind and select to perform just ULS checks, then create a matching combination with SLS wind and select to perform just SLS checks. Below is a suggested order of the steps to take to resolve problems with deflection under wind - note at any point you may decide to change you section sizes etc: ULS WindULS Wind + SLS Base FixityULS

Why do SCI P292 and Amplified Moments Method Frame Stability Checks fail?

For certain frame configurations these checks can be shown as Fail on the Design Summary because the elastic critical load factor is shown as 0.000. This will occur when there is the unusual situation where a member is changing from being in tension to compression along its length. The program traps this situation out because the calculation would otherwise have to assume the member in one state or the other along its entire length, which would mean the answer could be either too conservative or too unconservative. To check if this is the problem simply examine the axial force diagram for the

How do I model a nominally rigid base in Tekla Portal Frame Designer?

Nominally rigid bases should be modelled in accordance with clause 5.1.3.2 of BS5950-1:2000 which states"If a column is rigidly connected to a suitable foundation, the following recommendations should be adopted:a) In elastic global analysis the stiffness of the base should be taken as equal to the stiffness of the column for all ultimate limit state calculations. However in determining deflections under serviceability loads, a base may be treated as rigid.b) In plastic global analysis any base moment capacity between zero and the plastic moment capacity of the column may be assumed, provided

How does Tekla Portal Frame Designer determine the Combination Factors for additional crane loads?

From initial inspection it would appear that Tekla Portal Frame Designer uses smaller factors than required for a combination that includes Dead + Imposed + Vertical Crane + Horizontal Crane load cases Tekla Portal Frame Designer:1.2 Dead + 1.2 Imposed + 1.2 Vertical Crane + 1.2 Horizontal Crane However, BS5950:2000 Table 2 would give1.2 Dead + 1.4 Imposed + 1.4 Vertical Crane + 1.4 Horizontal Crane We follow the intention of the code but Table 2 contradicts itself for Imposed load acting with Vertical and Horizontal crane loads and is incomplete: Imposed with vertical = 1.4Imposed with

When considering Friction and Bearing on Bolts, what are 'Factor *d' and 'Factor *fcu'?

Solution Where bolts are solidly cast into concrete the bolts can be relied upon to resist shear. The design may be based on effective bearing length in concrete of 3d and an average bearing stress of 2 fcu. Where bolts are not solidly cast into concrete (i.e. adjustable) some allowance can be made for bearing on the bolts. Factors of 3 and 2 respectively assume the grout provides the same resistance as if the bolts were solidly cast (un-conservative), factors of 0 and 0 assume the grout provides no resistance (conservative). It is down to the individual engineer which values they use.

Why does my toe plate connection fail plate bending regardless of the plate thickness?

Solution This toe plate connection will have a Mode 1 failure.  To ensure that there is sufficient rotational capacity in the connection for it to be considered as "simple", only Mode 1 failure [Complete End Plate Yielding] is allowed. If other failure modes become critical the following parameters can be adjusted so that Mode 1 becomes the critical failure mechanism:   Bolt gauge Bolt pitch Bolt diameter Bolt end distances Toe plate/end plate thickness If you refer to the BCSA 207/95 Joints in Steel Construction: Moment Connections - P18 then this identifies the failure modes.

Compression weld thickness for angled beam

When the compression flange has a properly sawn end which is perpendicular, a bearing fit can be assumed between the flange and the end plate.  For beams, nominal 8 mm welds can be assumed to suffice, for lighter beams with a flange thickness of 12 mm or less then 6 mm welds can be assumed to be appropriate.  For haunches from section cuttings, the same nominal welds are required but with increased leg length to allow for the angle of the incoming haunch flange. S > =  1.4 *s_nom/(min(cos((90 – qh)/2), 0.7) + min(cos((90 + qh)/2), 0.7)) Wheresnom = the nominal weld sizes given for the beam
