BS 8110-ii:1985 Foreword This part of BS 8110 has been prepared nether the direction of the Ceremonious Engineering science and Building Structures Standards Committee. Together with BS 8110-ane it supersedes CP 110-1:1972, which is withdrawn. BS 8110-1 gives recommendations for design and construction. These recommendations chronicle particularly to routine edifice construction which makes up the majority of structural applications; they are in the class of a statement of blueprint objectives and limit state requirements followed by methods to ensure that these are met. Generally, these methods will involve calculations for ane limit state and simple deemed-to-satisfy provisions for the others; for example with reinforced physical, initial design will commonly exist for the ultimate limit land, with span/depth ratios and bar spacing rules used to check the limit states of deflection and cracking respectively. This approach is considered the most appropriate for the vast majority of cases. However, circumstances may arise that would justify a further assessment of actual behaviour, in add-on to simply satisfying limit land requirements. This role of BS 8110 gives recommendations to cover the more than unremarkably occurring cases that require boosted information or culling procedures to those given in BS 8110-1; thus this function is complementary to BS 8110:Office 1. Notation The numbers in square brackets used throughout the text of this standard relate to the bibliographic references given in Appendix A. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their right application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an within front embrace, pages i to iv, pages one to threescore, an inside back cover and a dorsum encompass.

BS 8110-2:1985Section ane. General11.i ScopeThis part of BS 8110 gives recommendations for the blueprint and construction of structural physical thatarise in special circumstances and are not covered in BS 8110-1.This part gives guidance on ultimate limit state calculations and the derivation of partial factors of safety,serviceability calculations with emphasis on deflections nether loading and on cracking. Furtherinformation for greater accuracy in predictions of the dissimilar strain components is presented. The needfor motility joints is considered and recommendations are made for the provision and pattern of suchjoints. General guidance and broad principles relevant to the appraisement and testing of structures andcomponents during structure are included.NOTEThe titles of the publications referred to in this standard are listed on the inside dorsum comprehend.one.two DefinitionsFor the purposes of this office of BS 8110, the definitions given in BS 8110-1 apply, together with thefollowing.autoclaving curing with high-pressure steam at non less than i.0 N/mm21.3 SymbolsFor the purposes of this part of BS 8110, the following symbols utilize.*fpartial condom cistron for load*mpartial safety factor for the strength of materialsfycharacteristic strength of reinforcementfcu characteristic strength of concrete BSI 07-2001 1 8. 2 blank 9.

Methods of assay for the ultimatelimit state22.1 GeneralBS 8110-1 provides methods by which the requirements of the ultimate limit country (ULS) may be satisfiedfor well-nigh normal situations in a reasonably economical manner, from the point of view both of design effortand of cloth usage. Situations do, however, occasionally arise where the methods given in BS 8110-1are non straight applicable or where the use of a
