Calculation technique of

The reinforced concrete strengthening slabs are the most popular main coverage of slopes. In order to describe the type of the environmental impact on strengthening slabs, a mass of initial data must be collected. Calculations technique of reinforced concrete strengthening slabs in accordance with building standards and regulations of various countries were investigated. The merits and demerits of each technique were discussed. Theoretical model for calculation of reinforced concrete strengthening slabs in accordance with analysis of building standards and recommendations of various countries is presented and corrected with the data obtained from the field investigations in Lithuania. The main conclusions: thickness of reinforced concrete strengthening slabs should be calculated in accordance with [20] and some corrections: wind load should be calculated in accordance with [4] for wave impact; ice and waves performance, necessary parameters should be obtained in the field investigations; the main ice load models and components, ice failure processes should be analyzed in accordance with [8]Vytauto Didžiojo universitetasŽemės ūkio akademij
