This article presents a simulation of the design scheme of a monolithic floor slab in the LIRA-SAPR 2013 software package. The calculation is based on the finite element method. The calculation of the floor slab is made as part of the entire building, taking into account the rigid coupling of the columns with the slab. The analysis of the results of static analysis is carried out and the selection of reinforcement for the slab is performed.

If defects are found in the foundation of an already constructed building or if the load on it increases, it is necessary to examine it and, if necessary, reconstruct it. The foundation of the building is a supporting building structure and the safety of the entire structure as a whole directly depends on it, therefore it is so important to make repairs on time. This article provides one of the methods used in construction to strengthen the strip foundation by adding broadening plates.

The substances released during the operation of automobiles are a mixture of products of complete and incomplete combustion of fuel. They contain several gaseous substances that are toxic and are dangerous to human life and its environment. Preventing and reducing dust effects are essential to protect human health.

Dust pollution of an asphalt concrete enterprise poses a danger to the public and the environment. Planning protective measures reduces dust exposure, which is really necessary to protect human health from a wide range of chronic diseases caused by dust pollution. Development and analysis of new solutions and methods to combat dust exposure are priorities.

Radon is universally present in the atmosphere and is the most important natural source of radiation. The highest radon doses relate to staying in buildings. However, the damage from radiation exposure to radon is associated with the progression of lung cancer and the premature death from this disease of people exposed to radiation. The application of the principle of optimization of radiation protection in a radon exposure situation is complicated by the fact that a number of tasks remain ignored.

At present, more and more attention is being paid to the radiation safety of the population, in connection with this new devices are being modernized and modernized, to improve the state of protection of present and future generations of people from the harmful effects of ionizing radiation for their health. The article considers the key aspects in working with such equipment and suggests measures to reduce the risk of working with it, primarily for personnel, especially in emergency situations.

The number of programs for modeling and design of buildings is great and continuous expansion of industry of creation objects cannot be stopped by high technologies. The most part of Russia's origin companies pay attention to foreign products despite great presence of domestic segment on the market. In the article will be considered the domestic software package Renga and also underlined his own advantages over existing analogues.
