Modern computer methods of multivariant analysis of a tall building

Abstract

At the beginning of this material to familiarize the reader with the definition of a high building and shows how modern, dynamically developing urban centers and with their growth, increasing the demand for housing high. This is confirmed by the examples presented in the article, the tallest buildings in the world. In this paper we present a variant static analysis of building construction high. It was carried out on the computational model described in point. 2 Calculations were performed in Autodesk Robot Structural Analysis 2012. In the first embodiment focuses on the calculation adopted discretization effects. The analysis was four computational models vary in terms of the finite element shape (square or triangular) and the maximum dimension of the finite element (0.50 m or 1.00 m). We analyzed the behavior of the structure according to the modeled subsoil on which it was set. In this variant, have been studied in two models of the object. In one model was taken into account susceptibility of the ground, while the second vulnerability is omitted and assumed the rigid connection. Another important problem that the stiffness of the building is analyzed, namely the effect of increasing stiffness are located inside the object individual components. Another element that was tested in the calculation of their time and memory occupation. In the last paragraph of articles presents the results of analyzes with figures obtained from the calculation. Selected elements more fully described in the tables. Analysis results were compared with each other and makes appropriate proposals, which were presented in the results of the subsequent variants of the analysis.
