Abstract
During the past 12 years, research project regarding time-dependent behavior of concrete elements is ongoing continuously at the Faculty of Civil engineering in Skopje. Experiments were performed on different types of concrete: prestressed, normal and high strength and steel fibre reinforced concrete, with various loading histories. The time-dependent changes in strains, deflections and crack widths were observed in a period of 400 days. This paper presents the effects of variable load on time-dependent behaviour of different types of concrete elements and proposes methodology for determination of coefficient ψ2.
