Important Note – These are descriptions to changes implemented in WoodWorks Sizer for version 10.1 and may not reflect current program behaviour.
The changes listed below were made to the Additional Data section of the Design Check output for CLT members.
In the Factors table:
The program was incorrectly displaying the values of shear and bending resistances Vr and Mr under f. it now displays the bending strength fb and rolling shear strength fs. as per O86 8.4.3.1 and 8.4.4.2.
The factor Krb for CLT design is now output. This factor is 0.85 for y-axis design and 1.0 for x-axis.
The row in the factors table for Deflection which showed an asterisk (*) and nothing else has been removed.
The asterisk that this line referred to in the Calculation section has also been removed.
In the Factors table, the program now outputs the rolling shear strength Fs and bending strength Fb and from 8.4.4.2 and 8.4.3.1. Previously it was mistakenly showing the shear resistance Vr and moment resistance Mr , but they are already shown in the Analysis vs. Design table.
A caret was added to the unit output for Seff and EIeff. i.e mm3 is now mm^3 and kN-mm2 is kN-mm^2, and similarly for imperial units.
In the column for lateral support factor KL, the rows for moment resistance Mr+ and Comb’d Mr now show a dash (-) instead of a 1.0, because KL is not applied to CLT according to O86 8.4.3.1 .
In the Calculations section:
An line reading e.g. Total deflection = 2.0 dead + "live" has been added. 2.0 is the is creep factor for dry service from O86 A8.5.3.2; however, this can be changed via an input in Load view.
The transverse axis values of EIeff and GAeff had a subscript z, e.g. GAzeff and for the longitudinal no subscript. The program now shows these with x and y subscripts and with a bracket, e.g. (EIeff),y as per O86 8.4.3.1.
The effective section modulus Seff from O86 8.4.3.1 is now output.
The moduli of elasticity E and E⊥ and the shear moduli, G and G⊥ from O86 8.4.3.1 and 8.4.3.2 have been added.
The labels Deflection and Moment have been removed as some of the data in each line can apply to both.
Extra blank spaces beside EIeff have been removed.
The member description in the Design Check has been changed as follows
The lateral support spacing output higher than that input by about 5-10%, for both metric and imperial formatting. This has been corrected.
For metric output, the spacing is now shown in whole millimeters rather than 2-digit accuracy.
The following changes have been made to the output of information pertaining to bearing design of column supporting members.
In the Design Check under Load Combinations, remove the reaction R and bearing capacity Cap have been removed because this information exists as Qf and Qr in the Analysis vs. Design table. The bearing length Lb and bearing factor Kb have been moved to the Calculations section. Kb has been renamed KB.
For wall panels and wall studs and in Column mode, the support bearing reaction and capacity were output in the Design Check under the Critical Load Combinations and in the Force vs. Resistance table. It has been removed from the Critical Load Combinations.
For beam or joist members with column or wall supports, the program displayed bearing factor KB support and size factor Kzcp sup as 1.00 in the Bearing Design table of the Design Check. These rows now show a dash (-) as they are not applicable to members loaded for compression parallel to grain, according to O86 6.5.6.
previously it contained only reactions. As it now includes support bearing design, it is called Maximum Reactions and Support Bearing.
The following changes have been made to the output of fire design information
The Fire sub-section under Calculations in the Design Check output report has been reorganized and changed as follows:
For column and wall fire design, in the Factors table of the Design Check, the row for modulus of elasticity now shows E, specified modulus of elasticity from Table 8.2.4, which is used in the calculation of the slenderness factor Kc according to B.6.4. Previously it was showing the E05, the modulus of elasticity for non-fire calculation of Kc.
The program was displaying nonsensical values in the material specification of the Design Check output for the number of fire-exposed sides when the NBC D-2.11 fire design method was selected. This has been corrected.
The required fire duration input in Beam view has been moved to the Calculations section from the specification of member materials, as it is not a property of the beam itself. To indicate that this line is about fire design, the word fire has now been incorporated into the number exposed sides and removed from Fire protection.
For I-joists, the table that for other materials was called Maximum Reactions, Bearing Resistances, and Bearing Lengths was called just Maximum Reactions, because
The program was showing values of shear fracture strength Ff and CLT rolling shear strength fs to one decimal place in the Factors table of the Design Check output. These have now been changed to show values up to two decimal places, because these are calculated rather than published values, which only require one decimal place.
The program was displaying bearinguplift restraint instead of uplift restraint, bearing in the warning note listing failing design criteria in Design Check output whenever both Simpson Hanger uplift and bearing failed. This has been corrected.
In the Bearing and Supports table, when Simpson Hanger is selected as the Support type, the line showing the critical load combination for each support under Des Ratio has been moved to be below the Support, to which it applies, rather than under Uplift, and a load combination line has been added for the Uplift criterion.
Furthermore, in the Load Combinations section of the Additional Data, lines for each support which experiences uplift have been added showing the full load combination description, similar to the existing lines for support bearing.
In the Design Check output Maximum Reactions and Bearing table, the word "Resistance" has been changed to Capacity.
For cantilevered members in beam mode, Sizer was often mistakenly showing a note regarding maximum reactions being from a critical load combination other then the one used for bearing design, and under Critical load combinations in the Additional Data, it was showing a 0 for the load combination number for bearing at some supports, rather than the critical LC number.
The correct load combinations were used for design, so this was a display issue only and has been corrected.
In some rare cases, the program the program output the wrong critical load combination number for bearing design in the Design output in the Bearing Design table and in the Critical Load Combinations. The critical bearing design ratio shown for both the beam and support for were also based on the wrong load combination, however design was based on the correct load combination.
This happened when the maximum response of one or more other load combinations was found to be nearly equal to that of the critical load combination. It has been corrected.
A line regarding deflection in Additional Data has been re-worded. "Live" deflection = Deflection from all non-dead loads (live, wind, snow..) now appears as "Live" deflection is due to all non-dead loads (live, wind, snow..).
The following symbols did not line up with the symbols in the design ratio column in Force vs. Resistance table in the Design Check. Sizer now aligns them
The symbols Qf/Qr for column bearing reaction and capacity.
The symbols Pf/Pr for factored axial load and compressive resistance for the b-face direction Axial b.
The following changes have been made to the design note that appears when Simpson hangers have been selected as a bearing support:
The note has been re-worded so that it no longer refers to the county edition of the Simpson hanger catalogue.
The misspelling of the word adjusts was corrected.
The output note regarding continuous support under the Loads table was in a fixed pitch font intended for table data. It now has a variable pitch font like the rest of the notes.
In the Analysis vs Design Table of the Design Check output, a space has been added to the identifier of spans less than beam length / 999.9, that is <L/999. Is changed to < L/999.
