Scientific and technical support of industrial construction with increased pitch of load-bearing walls in seismic areas
Abstract
This work is concerned with the solution of a number of problems that arise during the experimental industrialized construction of the structural systems with increased pitch of loadbearing walls on the example of the project that is implemented by the “Collective Company BUDOVA”. Analysis of world and domestic experience in the design and construction of the large-panel buildings in seismic areas, in-place tests of the results of the devastating earthquakes demonstrates the significant advantages of such structural systems. The reason for this is firstly the significant stiffness and essentially improved quality of structures that are manufactured in the factory conditions. Secondly, the industrial construction permits to reduce the construction period and the labor intensity during the manufacture and the installation which lead to the reduction of the construction value. Third, the damage to the large-panel buildings during the earthquakes as rule is 1-2 degrees lower than to other structural systems. It is worth to remark that the use of the spans more than 6.4 m was not carried out, with this all mentioned advantages. Today there is a significant demand for the planning decisions with the increased spans in the market of residential and public estate. That`s why the direction of seismic resistance of the industrial construction systems with increased pitch of load-bearing walls is relevant. It is necessary to refer the features of the calculation models formation, the calculation and the analysis of results to the first-order problems. To solve the problems arising during the calculation models generating and the calculation process, the preprocessor and calculation tools of the software complex LIRA-SAPR was modified, which was simplified the models formation and calculation with taking into account the work features with allowance for nonlinearity. Compensatory measures have been developed to solve the constructively problems connected with the deviation from the constructively requirements of DBN B.1.1-12, to verify which a set of experimental laboratory and in-place studies investigations were conducted, and which confirm the possibility to apply of the proposed system in the areas with a level of seismic effects 6-8 points.
