CALCULATION OF A MONOLITHIC COLUMN FOUNDATION FOR A REINFORCED CONCRETE COLUMN OF A MULTI-STOREY BUILDING IN LVIV

Problem statement. In modern construction of residential and commercial buildings, bridges and other structures, columns are often the main load-bearing elements. Different in the way they are manufactured and in their characteristics, these building elements serve as the basis of the framework on which all other building structures are placed. However, in order to have a strong, durable and, most importantly, correct construction of the whole structure, the columns should be installed with minimum deviations from the design values. This is why a great deal of attention is paid to the foundations in the design and implementation of the project. The purpose of the article is to develop a calculation of a monolithic column foundation for a reinforced concrete column of a multi-storey building in Lviv based on theoretical research. The design is based on theoretical studies and is based on the design of a monolithic column foundation for a multi-storey building in Lvov, taking into account the dimensions of the foundation, the soil characteristics, the self-weight of the foundation and the longitudinal reinforcement coefficient. Analysis of publications. Studying not only foreign, but also domestic current theoretical developments and practical experience will allow the objective to be achieved. There are examples among European countries that largely meet the current requirements. Results of the study. The most common soils in Lviv are chernozem, eluvial and peat-bog soils. The climate in Lviv is moderately continental with mild winters and warm summers. With these data, the dimensions of the monolithic columnar foundation for a multi-storey building are calculated and its reinforcement is determined. The strength of the monolithic columnar foundation for the reinforced concrete column of the multi-storey building is tested for the punching strength. Based on the results of the calculations, it is determined that the foundation is sufficiently strong under the column.Conclusions. In this article, the characteristics of soils and climatic conditions of the construction area in the city of Lviv were investigated. The dimensions of the foundation's underside, all dimensions of the foundation and the pressure on the ground under the underside from the design load were calculated. The reinforcement area of the foundation footing was selected and the strength of the foundation was tested for push-through.
