Strengthening of existing structures – Case study ‘Hotel on Pashko Vasa street N051, Prishtina’

Session

Civil Engineering, Infrastructure and Environment

Description

Existing building structures have always been a topic of concern for owners, stakeholders, engineers and researchers, considering different motives and interests. In addition to socio-economic, political, aesthetic and cultural reasons, the role of structures in any existing construction can be, or should be, the main issue when dealing with preservation and/or rehabilitation of all heritage buildings. However, when structural reconstruction is required or imposed due to any type of phenomenon such as changes in the configuration, modification or use of the structure, reconstruction may be unavoidable. It is clear that this issue is extremely broad, in the sense that interventions are highly dependent on a large number of different conditions and factors, for example, structural strengthening due to increased loads resulting from modification of use may lead to interventions other than those required to meet design requirements. Furthermore, access to existing structures is still an issue that requires special attention in current design practice; in fact, it is common that the design of the reinforcement project for existing structures in accordance with the relevant standards may become practically or economically unfeasible. Last, often types of reinforcement techniques can be proposed in its design, for which the designer can face difficulties in evaluating them to choose a more rational option. The purpose of this paper was the case study in question, where the critical questions and possible solutions were highlighted through it. The relevant information of the existing structure is collected mainly through various destructive and non-destructive testing. The tests provided, among other things, a lot of input regarding experiences or practices in reinforcement methods. The knowledge gathered from the tests was essential information about reinforcement methods. Then, taking into account the architectural aspects, different methods were selected and further evaluated through supplementary calculations. The results of the case study show that there are many aspects to consider, but also that many solutions are available with the development of new working techniques and types of materials.
