instantaneous elastic deformation produced upon stress application is often also separated from the creep deformation Interest in creep and shrinkage has been rising as concrete structures more susceptible to its effects have been appearing and structural damages or failures were being experienced The first extensive research which
The improvement effect of a new strengthening strategy on dynamic action of masonry structure by installing prefabricated concrete walls on the outer facades is validated by shaking table test presented in this paper We carried out dynamic tests of two geometrically identical fivestory reduced scaled models including an unstrengthened and a strengthened masonry model
TEK 141B Section Properties of Concrete Masonry Walls ref 6 provides typical values for the net moment of inertia I n and crosssectional area A n for various wall sectionsIf the value of the bending stress f b given by Equation 1 is positive the masonry section is controlled by tension and the limiting values of Table 1 must be satisfied
Under otherwise unchanged conditions the deformation of an exposed and loaded concrete member continues to increase The increase is due to creep under applied load and shrinkage from loss of moisture The engineering approach to estimating of deflection is to determine the instantaneous
Concrete belongs to a class of materials that can be called Strain softening indicating a reduction in stress beyond the peak value with an increase in the deformation as against the strain hardening behaviour commonly exhibited by metals like steel
