Effect of site actions on structural quality of buildings

Abstract

Negative and positive consequences caused by intensive execution loads and other actions during site period of buildings are analysed. The necessity to use probabilistic quality assessments and predictions for members, components, cross-sections and joints of structures exposed to inevitable deterministic and random site actions is discussed. Probability-based approaches on structural quality assessment of constructed members as autosystems representing multi-criteria failure mode in pre-use (execution) and use (service) stages are presented. Truncated probability distributions of resistances and statistical interactions between reliability margins or performance functions of structural members at their execution and service stages are taken into account. Site action effects as proof loads and their effect on structural safety indices of members are considered.
