This paper presents the method and results of a geographical altitude factor calculation to determine wind loading Calt at 9 meteorological stations in the Transcarpathian region. According to state building standards В.1.2-2:2006, the coefficient of geographical altitude is used to calculate wind pressure while positioning the building site at an altitude of up to 0.5 km it equals 1, at altitudes higher than 0.5 km, it is determined using the formula Calt = 4H–1. With the help of the suggested method, according to 23 directions and high wind coefficients, as well as data of meteorological observations from 1955−2005, the coefficients of geographical altitude were calculated to determine wind loading in July and January for each residential site, the peaks and mountain passes for the Transcarpathian region of Ukrainian Carpathians.

This article proposes to use parabolic-linear diagram of deformation of steel fiber concrete under the conditions of compression. General principles of calculation method of steel fiber concrete elements. with the use of deformation diagrams of steel fiber concrete, have been submitted. The aim of this study was to present a method for calculating the deformation and deformation capacity steel fiber concrete bending elements based on the results of experimental studies. Results of tensile testing of samples allowed to put forward an analytical description of the time dependence of the stress-strain of steel fiber concrete in tension and compression, and accurately calculate the load and deflection bending elements. The experimental significance of the bearing capacity of steel fiber concrete bending elements on the fiber from the sheet and theoretical implications calculated by the proposed method have shown quite a good convergence.

General data according to the conducted examination of some monolithic and precast steel concrete constructions of tower type, which were built by authors in Ukraine in the period from 2006 to 2011, has been described in this article. Conducted research has shown that unqualified implementation of separate works and factory defects in constructional elements are the basic reason of ruining the buildings and constructions. The materials of the analysis of the consequences from ruining buildings and constructions, and their elements from the defects during implementing building – assembly works, defects from technologic and random impacts are important in the way that from this analysis certain thoughts concerning making basic actions, which are directed on dissolution of different kind of defects to provide reliable operation of buildings and constructions, can be done.

The paper deals with the problem of the acoustic treatment using modern material technology in the modernization of old interiors. On the example of an auditorium with approved acoustics, that was built in 1962 and is located at the Lviv Polytechnic, some important directions in handling this type of object was shown. The acoustic measurements of the room showed, that structures used in the 60s are acoustically proper, but planned renovation should be based on modern technologies.
