Abstract

In view of location and tight work schedule of civil projects, more and more frequently the various kinds of work overlap each other in space and time. Hence, their interactions need to be anticipated. An example of such works are pile driving which generate vibrations, which begs a question whether and to what extent they affect proper operation of other structures being constructed at the same time, e.g. reinforced concrete elements. This paper deals with the problem of steel-to-concrete adherence in reinforced concrete elements by providing mechanism of adherence destruction, methods use to determine adherence stresses and outlining analytical and numerical methods. Examinations on how vibrations affect fresh concrete mix are provided in the latter part of the paper. At the end, further direction for development is discussed.
