Manual for the design of steelwork building structures to Eurocode 3 (2010)

Two errors have also been found in the Institution’s Manual for the design of steelwork building structures to Eurocode 3 (2010).

On page 64 the last paragraph of Section 4.4.7.3 on the resistance of headed studs is incorrectly worded. The error means that the strength of studs is overestimated.

On page 95 h and h1 in Figure 8.6 have been transposed. Using them incorrectly will give a conservative result. The online version of the Manual held on IHS has been updated to incorporate these amendments. All copies of the manual sold from 10 May 2011 will be despatched with these errors corrected.

The corrected pages 64 and 95 are given in the March 2011 amendment which is available here.

 

 

Manual for the design of building structures to Eurocode 1 and Basis of Structural Design (2010)

Typographical errors have also been found on pages 24, 160 and 162 of the Institution’s Manual for the design of building structures to Eurocode 1 and Basis of Structural Design (2010).

On page 24 note b of Table 2.4 should be deleted as the single source principle does not apply in this case. In the first line of Section 8.2.4 on page 160 and in the first column of Table 8.2 on page 162 references are made to Section 8.10. All of these should be changed to Section 8.4.10. The online version of the Manual held on IHS has been updated to incorporate these amendments.

All copies of the manual sold from 10 May 2011 will be despatched with these errors corrected. The corrected pages 24, 160 and 162 are given in the March 2011 amendment which is available here.

 

 

Manual for the design of steelwork building structures (Third edition, 2008)

Two amendments have been issued: one in December 2008 and one in March 2011

The December 2008 amendment contains four graphs that were mistakenly omitted from Appendix D. The December 2008 amendment is available here.

The March 2011 amendment concerns an error which has been found in an equation on page 37 that relates to moments about the rafter hinge position and a check on whether the correct mode of failure has been assumed. Use of the equation as published could mean that the check is passed when in reality it should have failed.

All copies of the manual sold from 10 May 2011 will be despatched with this error corrected. The corrected page 37 is given in the March 2011 amendment which is available here.

The online version of the Manual held on IHS has been updated to incorporate all of these amendments.

 

 

Manual for the design of plain masonry in building structures to Eurocode 6 (2008)

Two amendments have been issued: one in April 2010 and one in April 2011.

The April 2010 amendment deals with two errors that have been found in the Manual for the design of plain masonry in building structures to Eurocode 6.

Firstly on page 72, which is non-conservative. The final sentence in Section 5.3.6.3 is incorrect because it makes no allowance for the slenderness of the wall or column being designed. If used where the middle height eccentricity is calculated to be less than 0.05t, it will lead to an overestimate of the vertical load capacity of the wall or column, if the middle height reduction factor governs. The correct value of the middle height reduction factor should be obtained from Figure 5.13 or the appropriate equation (see Annex G in EN 1996-1-1).

The second error is a typographical error on page 76. In the first equation in Section 5.3.8 the 't' should not be subscript as it is multiplied by the other terms.

All copies of the manual sold from 26 April 2010 will be despatched with an amendment slip with the sentence deleted and the subscript altered. The corrected pages 72 and 76 are given in the April 2010 amendment which is available here.

The April 2011 amendment deals with changes to three pages.

On page 76, the equation for determining the slenderness reduction factor at the mid height of wall has been wrongly set out repeating a mistake in the base Eurocode that was not corrected until after the Manual was published. Additionally the last paragraph on page 94 and procedure ii) on page 95 have been reworded to clarify their meaning.

All copies of the manual sold from 10 May 2011 will be despatched with these errors corrected. The corrected pages 76, 94 and 95 are given in the April 2011 amendment which is available here.

The online version of the Manual held on IHS has been updated to incorporate all of these amendments.

 

 

Manual for the design of timber building structures to Eurocode 5 (2007)

The amendments issued in May and July 2008 to the Manual for the design of timber building structures to Eurocode 5 are available for download (see below).

There are three sets of amendments, two for the hardcopy of the Manual and the other for the CD.

Please note that the CD amendments have been incorporated into Version 1.01 of the CD, distributed with copies of the Manual sold since 24 May 2008.

  1. May 2008 amendments: Manual for the design of timber building structures to Eurocode 5 – hardcopy manual.
  2. May 2008 amendments: Manual for the design of timber building structures to Eurocode 5 – CD (Amendment to CD Version 1.0).
  3. July 2008 amendments: Manual for the design of timber building structures to Eurocode 5 – hardcopy manual.

 

 

Manual for the design of concrete building structures to Eurocode 2 (2006)

  1. May 201 amendment: corrects Table 5.2 on page 28. The published coefficient in Table 5.2 used to calculate the shear at the end support of a continuous one-way spanning slab, should read 0.46F, the published 0.046F is incorrect and would lead to an unsafe result.
  2. August 2009 amendment: corrects Table 5.17 on page 65. In some cases this error can cause designs to be non-conservative.
  3. March 2009 amendment: corrects the expression for e2 given in section 5.5.4.3 on page 64 of the manual. Without this amendment designs will be non-conservative.
  4. March 2008 amendment: corrects the expression for k given at the top of page 39 of the manual.
  5. September 2007 amendments: available in two versions; one is for printing single sided and the other for printing backed. Please note: The content of both versions is identical

For best results the September 2007 amendments should be printed in A4 landscape with "shrink to printable area" selected to avoid the loss of the footer strip.

 

 

Standard Method of Detailing Structural Concrete. A Manual for best practice (3rd ed) (2006)

Two amendments have been issued, one in November 2006 and one in June 2011.

The November 2006 amendment relates to pages 185 and 186 in Appendix B and is available here.

The June 2011 amendment corrects a topographical error is in the equation for ultimate bond stress fbd on page 41 of the manual. This error will increase the ultimate bond stress by 1.5 times and will consequently result in the basic required anchorage length lb,rqd being underestimated by 33%.

The correct page can be available here.

The related tables 6.1, 6.4, 6.7, 6.9 and 6.11 have been checked and are in accordance with the correct form of the equation.

Hard copies of this publication bought from 4 July 2011 onwards will incorporate these changes. The online version of the Manual held on IHS has been updated to incorporate all of these amendments.

Structural effects of alkali-silica reaction. Technical guidance on the appraisal of existing structures (1992)

An addendum has been produced giving an update on the developments that have occurred since this report was published in 1992. The preferred term for this problem is now alkali aggregate reaction or AAR. Rules introduced and developed in the 1980s recommended limiting the alkali content in concrete in the UK. This has achieved the objective of minimising the risk of AAR in new construction. The number of cases of AAR worldwide continues to increase and more structures have needed major remedial work or replacement. There are now 47 countries where AAR has been reported. However RILEM, which is drawing up an atlas of known reactive rock types, has found that many owners and countries are reluctant to publicise cases.

The online version of the report available on IHS has been updated to incorporate this addendum. All copies of the report sold after 5 May 2010 will be despatched including the addendum which is available here.
