Experimental Research of Destruction of Internal Field of a Slab-Column Structure Caused by Overload

Abstract:

Slab-column structures used in design and construction work are one of the typical kinds of structures used in building industry. The emergence of factors unexpected at the designing stage can lead to collapse of the structures. The paper presents experimental investigations of the central field of the continuous floor. The research was conducted on a nine-field slab with dimensions 9300×9300×100 mm. The aim of the research was to observe the behaviour of the experimental model in the time when excessive load is exerted. The model was prepared using high ductility steel (ε_uk>7.5%) in order to determine the possibility to induce tensile membrane action. The paper presents basic geometrical and material data, the research methodology, the description of the system of loading, the description of the measurement system, and the obtained measurement results. The last part summarizes the conducted investigations.
