Abstract
Substructures of reinforced concrete building frames in a zone of potential local collapse are considered. To assess their resistance in special limit states, an analytical calculation model is proposed. The validation of the presented computational resistance model is based on the results of 22 tests of typical substructures of monolithic and precast building frames, as reported in the works of various researchers. Using the proposed analytical model, a parametric study was performed on the influence of the following factors on the resistance in special limit states: the ratio of the beam cross-sectional height to the span, and the ratio of the effective section depth to the total depth.
It is proposed to assess the mechanical safety of key structural elements under accidental conditions using an ultimate limit surface formed by the joint consideration of local strength criteria for each type of ultimate internal force, without analyzing a single critical cross-section. Such a surface is constructed...

Evolution of methods for determining shear resistance in reinforced concrete structural elements led to the approach proposed in the new Model Code 2020. It is based on the strut-and-tie model and allows for verification on three levels of approximation. In this paper, the new approach is presented and illustrated for...

The paper presents the results of an experimental study of the residual strength of a reinforced concrete partition after thermal exposure using the rebound hammer method. Measurements were performed before and after fire exposure at 28 control points located at four height levels of the structure. It was established t...

Confined masonry is widely used in areas subjected to seismic, dynamic, and cyclic actions. Increasingly, confined masonry is also being used outside earthquake-prone regions as an alternative to reinforced masonry, which is reflected in the provisions of Eurocode 6. There is a clear research gap concerning the behavio...
