Thermal and humidity conditions inside enclosing structures made of thin-walled galvanized steel profiles

Abstract

The purpose of the thesis was to study the possibility of application of thin-walled galvanized steel profiles produced by Ruukki Rus LLC as a part of en-closing structure in the climatic conditions of St. Petersburg. The main tasks of the work were: to develop the structure of external wall with the use of thin-walled galvanized steel profiles, to develop a program for automatic calculation of the thermal and humidity parameters, to study thermal and humidity regime inside the wall in the climatic conditions of St. Petersburg, to check that operat-ing conditions of thin-walled galvanized steel profiles correspond to recommendations of N.P. Melnikova Research and Design Institute of steel building structures within humidity parameter. The study was requested by Ruukki Rus LLC because of the need to prove that thin-walled galvanized steel profiles inside the external wall structure are allowed to use in St. Petersburg and to prepare the data for the State expertise’s permission.

Data for this study was gathered from scientific literature. Calculations were made by manual methods.

The results of the study demonstrate the applicability of this kind of structures in the climatic conditions of St. Petersburg. Further, the results can be used for obtaining the State expertise’s permission and can simplify the process of le-galisation of steel profiles use. The data obtained can be included in the base of documents for the design, calculation and operation of building structures with the use of light thin-walled steel structures. This base will help to decrease the number of emergency cases in construction and increase the reliance of consumers.
