Knowing the movements of chimneys (classified as the slender structure) has a very important role in the process of their construction and operation. Problem affects both the shaft and foundation of the chimney. Exceeding the maximum displacement of these buildings could in turn lead to the failure or construction catastrophe. This article aims focus on issue on the value of reinforced concrete chimney displacement measured geodesic projection method (without the knowledge of wind loads and nature of displacement during the measurement) and the theoretical displacements obtained for the adopted models in the computer calculation, ie static model and a dynamic model. The article presents the numerical analysis of reinforced concrete chimney displacements, ie shaft and foundation in terms of its displacement caused by standard wind load q in acceptable terms of the foundation and on the hypothetical loads (real) wind, which was carried out geodetic measurements. For analysis used Autodesk Robot Structural Analysis and MSC Marc for accepted model of shaft and substrate flexibility / stiffness Kz. The results obtained modeling the chimney (the analysis of static and dynamic - having a very important role in modern design of slender structures) carried out in two programs, and obtained during the surveying are presented in graphical form table.
