The phenomenon of progressive collapse according to Russian norms

Abstract

Finnmap Consulting Oy acted as the client. The research had several targets. The first one was to introduce the concept of progressive collapse and describe the causes and consequences of this type of failure. The second target was to highlight the main measures which can help to ensure the stability of a building against progressive collapse, to emphasize how it can be solved in Russia ac-cording to not numerous standards. And the third, the most important target lies in the issue of practice – to study possible methods of calculation, to identify the features of this process and to show the example of calculation. The first part of the thesis gives the definition of the main concepts – progres-sive collapse and survivability, describes the types of progressive collapse and its causes. Also this part includes information about status of issue and gives examples of challenges, which can be met during studying the proposed topic. The second part describes in detail the methods to prevent progressive col-lapse, including requirements for design, rules for choice of construction system and materials and recommendations for calculation. Measures for existing build-ings are also included in this part. The third part of the thesis contains the method of calculation and gives the consequence of calculation step by step. And the last part includes the description of several attempts of calculation with comments and conclusions which were made during calculations. As a result the clear concept of progressive collapse was received. The possi-ble methods of prevention of this failure were described. And the consequence of calculation with examples was presented. During study the emphasis was made on Russian norms and standards such as STO, MDS and Recommendations.
