Wooden intermediate floor slab as an alternative to reinforced concrete intermediate floor slab

The thesis addresses the technological, economic, time-related, and acoustic comparison of two intermediate floor structures: a wooden floor slab and a reinforced concrete floor slab. The main goal is to compare and analyse the differences between the two structural systems, to evaluate and assess them in terms of time and cost, and to determine whether there is potential for wider use of the wooden intermediate floor slab in modern construction.

The introduction presents the construction materials, outlining the main properties that influence structural performance. The thesis is based on already executed case studies. For easier comparison, the reinforced concrete slab, more commonly used, is adapted to the existing case of the wooden floor slab.

For both systems, the technological approach of execution is described in detail, including phases and materials. Following this, a cost analysis of both intermediate floor slabs is carried out. Bills of quantities with prices are prepared for each case, forming the basis for a price analysis and construction cost comparison between the two systems.

In addition to the cost analysis, the thesis also includes a time analysis of construction, taking into account all technological phases required for slab execution. The time analysis investigates whether the execution of the given wooden intermediate floor slab case is faster than that of the conventional reinforced concrete slab. An acoustic analysis of both structures follows, focusing on sound transmission based on mass, with two case studies examined.

The question is raised whether the wooden intermediate floor slab can achieve acoustic properties comparable to those of reinforced concrete slabs. Furthermore, the thesis discusses the issue of providing affordable housing, with a focus on renovation in historic city centres.

Renovation using wooden intermediate floor slabs can, on the one hand, meet cultural and historical requirements for preservation, while on the other hand offering a fast and structurally lightweight alternative.

The thesis offers a comprehensive insight into the comparison of two structural systems and provides a useful basis for decision-making in the planning process of efficient and environmentally sustainable buildings.
