x-like biaxial voided concrete slab

Abstract

In the modern world, progress and development is a constant process. In order to build buildings with extraordinary and complex geometric shapes, existing building materials are improved and new materials are invented constantly, construction technologies are improved, as well as daily reporting programs are being refined, all this gives us new opportunities to design buildings with complex architectural shapes and come up with out of ordinary construction solutions.

One of the main structural elements of modern frame buildings is considered to be a slab, which is in a difficult stress-deformed state under the influence of static and dynamic loads. There are several types of slabs: conventional, flat, with a capital, waffle and voided slabs [1, 2]. The present paper discusses a certain type of voided slabs, more precisely, voided box-like biaxial slab. The structural elements of this type of slab create a unified rigid system. The structure is examined as a stand-alone structure as well as a part of the building. The study takes into account static and dynamic loads as well as seismic impacts in the form of an accelerogram. The paper emphasizes the advantages of using this type of rigid slabs in large span structures.
