| Popis: | Using stay-in-place cement board forms for construction of residential buildings of reinforced concrete is one of the effective methods of modern construction. In the process of production of construction materials despite tight control some defects in structures may form. In this regard, the reliability assessment of the construction technology in terms of quality is an essential task. To assess the reliability of the construction technology the methods of visual examination of building structures and instrumental measurement of detected defects were used. Mathematical processing of the quantitative characteristics of the qualitative parameters is performed by methods of mathematical statistics with the confidence α = 0,95. The study established the most common defects of building structures erected with the stay-in-place cement board forms, as well as identified the cause-and-effect relationships of their formation. The probability of simultaneous failure of the task by the quality parameters of at least one characteristic varies from Qmin = 0,082 to Qmax = 0,161 with the average value Qcp = 0,119, the admissible value specified in building code being Qmin = 0,2. Overall, the technology of constructing reinforced concrete residential buildings with stay-in-place cement board forms corresponds to the level of reliability according to the quality parameters set by the project documentation. |
