Examination of Defects in Joints of Large Panel System Buildings and Their Impact on Load-Bearing Capacity and Stiffness of Connections

Abstract:

Large Panel System (LPS) Buildings represent a significant portion of the housing stock, with many structures approaching the end of their planned design service life. Given the ongoing local and uncoordinated reconstructions and modernisations of LPS buildings, it is crucial to expand knowledge in their structural assessment. This study analyses the most common defects within joints and investigates their impact on the load-bearing capacity and stiffness of panel connections. Both analytical and numerical calculations are used for the analysis. The analysis indicates that defects (whether from assembly or from later interventions) found during inspections of various structures affect the stiffness and load-bearing capacity of the joints. Therefore, the calculation of a joint's load-bearing capacity, which considers its current condition, plays a significant role in the structural assessment.
