The article discusses modern approaches to the calculation of embedded parts using the most common computing systems in the design environment. The main purpose of the work is a comparative analysis of the stress-strain state of the support plates and anchor rods when calculating in various computing complexes in order to obtain the most reliable and complete results necessary for the designer to ensure reliability when designing components of building structures. In addition to the above, the article focuses on ensuring the rigidity of the support plates, in case of compliance with which, the nodal structural element is able to withstand a single impulse impact.

The article discusses modern methods for protecting load-bearing structures from progressive collapse, as well as methods for their calculation in extreme conditions, in order to ensure the safety of buildings and structures, reduce material damage and minimize human casualties as a result of emergency situations. The main purpose of the work is to identify the imperfections of existing methods for calculating building structures against progressive collapse, regarding multi-storey residential complexes, which are characterized by girderless frames, which have significant architectural advantages, as well as revealing the inaccuracies of empirical formulas used in practice for determining the coefficients of dynamic strengthening in tension and compression, which entails a calculation that does not correspond to the actual work of structures.

Keywords: beamless frame, progressive collapse, protection measures, calculations, dynamic coefficient, dynamic strengthening coefficient

The article deals with modern problems in the field of coordination of working documentation, due to the lack of regulatory documentation that regulates the clear time allotted for the preparation and approval of the developed documentation. The main goal is to obtain averaged time indicators based on the data of standard projects of objects, as well as to determine the degree of mutual influence of factors on the considered terms, in order to apply them in the preparation of a consolidated calendar plan of the organization provided to the technical customer for the conclusion of the contract, as well as to predict and reduce time indicators for the removal of comments and repeated requests.

Keywords: matching, matching organizations, average labor intensity, repeated requests, correlation and regression analysis
