“…One of the reasons for the rapid spread of defects is the opening of cracks in the RC structure. In the study [6], it was established that the load level of the opening shear crack was 53% higher than the load level of the appearing bending cracks. This dependence was derived for prestressed reinforced concrete T-beams based on experimental data.…”

This article presents research on the bearing capacity and methods of calculating reinforced concrete beams on the shear without internal shear reinforcement, which are strengthened with a composite FRCM system. The test samples were divided into two series: the first series—control, in which the variable parameter was the shear span (a/d = 2, a/d = 1.5, and a/d = 1); and the second series—reinforced by the FRCM system, without load, and strengthened at different load levels. The method of calculating experimental beams was tested according to the current code and data from the fib report. In this article, recommendations for determining the angle of inclined struts θ, the coefficient of the concrete shear strength CRd,c, and the coefficient of the load level at which strengthening is performed are proposed. The calculation with the these recommendations showed a good convergence of experimental and theoretical data in the 16–29% range, which is a much higher convergence than the calculation without these recommendations.

The Dybbuk Century

A little over 100 years ago, the first production of An-sky’s The Dybbuk, a play about the possession of a young woman by a dislocated spirit, opened in Warsaw. In the century that followed, The Dybbuk became a theatrical conduit for a wide range of discourses about Jews, belonging, and modernity. This timeless Yiddish play about spiritual possession beyond the grave would go on to exert a remarkable and unforgettable impact on modern theater, film, literature, music, and culture. The Dybbuk Century collects essays from an interdisciplinary group of scholars who explore the play’s original Yiddish and Hebrew productions and offer critical reflections on the play’s enduring influence. The collection will appeal to scholars, students, and theater practitioners, as well as general readers.

“…An investigated assessment algorithm was applied for crosssections of reinforced concrete elements under difficult stress conditions. The article (Karpiuk et al, 2021) is about the cracking process and the destruction of test beams. Also, the mathematical models of the crack opening width and the projection length of a dangerous inclined crack were obtained.…”

In the building industry, it is a frequent cause of damage to elements at different stages: during transportation, operation, installation, etc. Since replacing an element is not always possible due to various circumstances, it entails significant financial losses, logistics, and others. For this reason, the expediency of studying the effect of damage on the bearing capacity of reinforced concrete elements is growing. This effect is dependent on its type and has significant variability. In the case of the combination of the defect and damage in reinforced concrete elements, the complexity of the research of this element increases significantly. In this article is discussed: a review of damaged reinforced concrete elements; researching the influence of the damage and additional factors on the element; developed testing methodology for bending reinforced concrete elements with damage to concrete in a compressed zone with insufficient reinforcement, when performing damage to the action of the load and during the action of the load, is presented; the influence on the deformability and bearing capacity of the variability of damage on the sample with insufficient reinforcement is reflected, taking into account the factor of change in the load at which the damage is performed; a comparison is made of the dependence of the change in the actual height of the compressed zone on the change in the load on the elements; implementation of conclusions on the result of the study.
