Abstract
The paper presents the strength analysis of cast-in-place and precast structures in accordance with regulatory documents, which require clarifications, since the properties of such structures distinguish them from conventional reinforced concrete structures. These properties include the beginning of the deformation process, ultimate strain, physical properties, and others. The strength analysis of cast-in-place and precast structure is conducted with regard to these properties.
The proposed analysis is based on the load-bearing capacity exhaustion of deformed concrete or reinforcement and allows considering the different time of involvement in the deformation process of cast-in-place and precast structures as well different stress and strain properties of concrete. The experimental data are in good agreement with theoretical calculations.
