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.

Where do the design rules for toe plate connections come from?

  Toe Plate Connection The Toe Plate is a ‘Tekla’ connection that was developed by us using the principles set out in both of the green books (simple & moment) as described in the attached document.

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

Unable to activate Tedds/TSD license(s) - The underlying connection was closed

Unable to activate Tedds/TSD license(s). The underlying connection was closed. An unexpected error occurred on a send. Solution: Try to activate the licenses awhile later. Make sure that you have a proper internet connection speed, finalize all the pending critical Windows updates and restart your system.  If the problem still persists, activate the licenses from another machine using “Activate" >>  “Another Computer” option.

Tekla Structural Designer product bulletin February 2018 (PBTSD-1802-3)

Résumé of issue This issue relates to the design of steel braces for the BS Headcode (All Countries).  For braces subject to tension using flat, double-angle and structural hollow section (SHS, CHS & RHS), the tension capacity check uses the gross area Ag of the brace, rather than the net area Ae , potentially producing an unconservative design result. Occurrence This issue relates to Tekla Structural Designer 2015 (version 15.0.0.40) released in March 2015 and all subsequent releases

Résumé of issue This issue relates to the analysis model for buildings with 2-way concrete slabs supported by beams or walls for all Head Codes.  In specific and relatively rare circumstances the concrete slab 2D element mesh was not correctly connected to a supporting beam or wall.  Resulting errors in design forces would tend to be conservative for slabs but potentially unconservative for supporting beams/walls.  Where this issue occurred it would generally be clearly apparent from deflections and unexpected failure of slab design due to it spanning a greater distance.

Renumbering grid lines after importing a dxf

Question: I have imported a dxf file to use as a grid and find the grids are all numbered numerically. Is there a way to renumber the grid lines without editing each line? Answer: Yes, the following example will take you through importing the grid, changing the numbering format and finally renumbering the grid. Example Importing the grid When importing a dxf file as an Architural Grid, all of the lines are numbered numerically (1,2,3...) by default. These can be changed to have a series of selected lines numbered alphanumerically (A,B,C...). Note: The grids are numbered in the order they
