Simulation of an emergency situation of a digital architecture object

Abstract

The article considers information modeling an emergency impact in the study of the stability of a digital architecture building to progressive collapse with the help of a local destruction simulator using the finite element method. A non-linear processor was used, the calculations were performed by the step-iterative method with automatic step selection. When calculating a digital architecture building for progressive collapse, a technique in a quasi-static formulation was used. Measures were developed to effectively counter the emergency. Since the placement of stiffness floors in the current regulatory documentation is advisory in nature, the need to install outrigger floors in relation to a digital architecture building was studied. The concept of a building of digital architecture of a complex shape in the plan was developed. To determine the most loaded rod element of the calculation model, the calculation of the frame of a unique building was performed at the stage of normal operation. At the 2nd stage, this element was switched off from work, and a computational model was obtained for simulating an emergency. As a result of a series of numerical experiments, taking into account various scenarios of emergency impact on the frame of a digital architecture building, a constructive scheme of a unique building with outrigger floors was developed. The unique building resulting from shaping will have a low weight skeleton, taking into account the use of innovative materials. The collaboration of digital technologies and innovative materials will allow the construction industry to move to a completely new level of development.
