Experimental studies of interaction basic shapes made from concrete

Abstract

The results of the test piece of precast reinforced concrete slab of natural products. The experiment was conducted in accordance with the recommendations for the calculation of transoms frame type series 1.020-1/83, taking into account the joint work with the flooring. We checked the impact of flooring on beams with different-tions combining vertical and horizontal loads. The effectiveness of the interaction was evaluated by comparing the test results of the twin crossbars composed of overlapping and inde-pendent scheme. It was found that the work of the dowel connections is not sufficiently reliable, and the influence-of the horizontal load is virtually absent.
