BS 8110 deals with the structural use of concrete. It is published in
14、 three Parts: Part 1: Code of practice for design and construction; Part 2: Code of practice for special circumstances; Part 3: Design charts for singly reinforced beams, doubly reinforced beams and rectangular columns. The design charts in this Part of BS 8110 have been prepared in accordance with
15、the assumptions laid down in Part 1, with the intention that they may be used as standard charts and so avoid duplication of effort by individual design offices. This Part of BS 8110 reflects the change in the characteristic strength of available reinforcing steel and supersedes CP 110-2:1972 and CP
16、 110-3:1972 which are both withdrawn. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Sum

19、8110-3:1985 BSI 12-19981 1 General 1.1 Scope This part of BS 8110 covers design charts for singly reinforced beams, doubly reinforced beams and rectangular columns. These design charts cannot be used to obtain the complete detailed design of any member but they may be used as an aid when analysing t
20、he cross section of a member at the ultimate limit state. The charts have been based on the assumptions laid down in BS 8110-1, use being made of the parabolic-rectangular stress block throughout. Full details of the derivation of the charts are given in Appendix. NOTEThe titles of the publications
21、referred to in this standard are listed on the inside back cover. 1.2 Symbols For the purposes of this Part of BS 8110 the definitions of the symbols given in BS 8110-1 and BS 8110-2 apply together with the following which are used in Appendix. 1.3 Use of charts Design examples illustrating the use
22、of the charts are given in Appendix B. The values of K indicated on the column design charts are the additional moment reduction coefficients given by equation 33 of BS 8110-1:1985. 2 Design charts Design charts Nos. 1 to 50 are given on the following pages. fscStress in reinforcement in compression
