Investigation of longitudinal reinforcement contribution in shear punching of reinforced concrete flat slabs without transverse reinforcement

The shear punching of the reinforced concrete slabs is a complex process occurring when considerable force is concentrated on the relatively small area of a column-slab connection. An incorrect assessment of load capacity of slab under the punching shear may lead to an accident. One of the most significant factors affecting the slab capacity is longitudinal reinforcement. In this article much attention is given to the analysis of the longitudinal rebar impact on the maximum loading capacity of reinforced concrete slabs without transverse reinforcement affected by punching shear force using the finite element method. The results obtained via the finite element simulation are compared with laboratory tests and manual calculations carried-out using various methods represented in different national building Codes of practice

Human Capital in Russian Power Generating Corporations

The Russian energy industry is on the verge of major changes. The potential of existing technologies has been exhausted, and to ensure economic growth, the development and implementation of new approaches in the field of electricity generation is necessary. The human capital of enterprises is the most important driver of changes in the energy sector. The purpose of the article is to analyze the influence of factors characterizing human capital on the effectiveness of Russian power generating corporations. The study found that the efficiency of power generating corporations is most strongly influenced by the share of managers in the structure of employment and labor productivity. Such indicators as the share of specialists with higher education and staff turnover did not significantly affect the efficiency of power generating corporations
