Soil reinforcement techniques have always been used,whether to reinforce existing soils (Figure 1) by adding beaten or dark vertical inclusions in the soil,or to create retaining walls (Figure 2) by using soils remodelled and reinforced with horizontal reinforcement (strips,slicks,cellular structures,etc.) or short or continuous fibres.2.1.Shrinkage,Cracking and Deflection of Concrete StructuresIntroductionDesigning For ServiceabilityEffects of ShrinkageControl of DeflectionControl of Flexural CrackingConclusionsAcknowledgmentReferencesFor aconcrete structure to be serviceable,cracking must be controlled anddeflections must not be excessive.It must also not vibrate excessively.Concrete shrinkage plays a major role in each of these aspects of the serviceload behaviour of concrete structures.Thedesign for serviceability is possibility the most difficult and least wellunderstood aspect of the design of concrete structures.Service load behaviourdepends primarily on the properties of the concrete and these are often notknown reliably at tSee more on ejse12345Next(PDF) COMPARATIVE STUDY OF DESIGN OF WATER TANKSof the hoop reinforcement is gradually increased towards the top of the tank.Distribution and tempera ture reinforcement of 0.3% of t he gross section is provided in the vertical direction.
