β¦ Synopsis
The paper reports the results and analysis of an experimental investigation undertaken to study the deformational characteristics of high strength concrete under repeated uniaxial compressive loads.
Changes in the parameters like the elastic and inelastic strain, modulus of elasticity, mechanical hysteresis and stress-strain behaviour are studied in relation to the cyclic loads.
The research work has indicated a suitable criterion for defining .fatigue failure of concrete, and has established an empirical relation between the parameters, modulus of elasticity and fatigue life, for predicting the remaining fatigue life of a partially fatigued concrete prism.

The chloride permeability of normal weight concrete subjected to static and repeated compressive loading was evaluated by using the AASHTO T277 test method. The results of concrete under static loading showed that the application of loads up to 90 % of the ultimate strength had little effect on the
The purpose of the present paper is to examine the hysteretic stressstrain behavior of steel fiber reinforced concrete and steel fiber reinforced mortar under uniaxial compression and to propose mathematical expressions of stress-strain curves based on experimental data. The stress-strain relations
This paper presents an analytical method for quantitatively predicting the effects of cracking on the lateral deflection and stiffness characteristics of tall reinforced concrete buildings under service loads. The effects of cracking in tall reinforced concrete buildings can be considered using an e
