## SERVICEABILITY LIMIT STATE CHECKS

In chapter 4 and chapter 5, design procedure for the ultimate limit state (ULS) in bending, shear and torsion were described. It is necessary in practice to ensure that the structure can not only withstand the forces at the ultimate limit state but also that it behaves satisfactorily at working loads. The main aspects to be satisfied at serviceability limit state (SLS) are that of deflection and cracking. In this chapter checks that are normally used to ensure satisfactory behaviour under SLS conditions without detailed calculations are considered. These are known as ‘deemed to satisfy’ clauses. Methods requiring detailed calculations are discussed in Chapter 19.
