The impact of construction quality on the safety of prefabricated multi-family dwellings

Piotr Knyziak

Abstract

This study presents analysis of the safety of prefabricated buildings utilizing concrete large-panel technology in the context of building failures as a result of exceptional loads and in the context of their technical condition. Examples of incorrect construction and maintenance from on-site in- spections of 110 buildings in Poland are described. Lack of assembly alignment, elements of the structure not protected against corrosion, elements damaged during construction work, no re- pairs after exceptional loads, and lack of structural strengthening are discussed. The set of case studies of large-panel buildings undergoing partial progressive collapses investigated in this study describe how this type of building, despite the impact of all the imperfections of con- struction and maintenance, carry exceptional loads. A systematic de fi ning of the degree of ad- vancement of a progressive collapse in residential buildings in relation to typical damage ranges was proposed.
