| Title of the article | Stress-strain state of the loop joint of a large-panel building with progressive collapse |
| Abstract. | Problem statement. Ensuring the strength and reliability of prefabricated buildings directly depends on the design solution, strength and deformation characteristics of vertical and horizontal joints, technology and quality of their execution. This task becomes more complicated when designing buildings, taking into account the progressive collapse, predetermining the need to modernize standard solutions. The necessity of developing solutions that increase the resistance of large-panel buildings to emergency impacts leading to instant or prolonged destruction of individual structural elements and assemblies is considered. Due to the presence of elements of the loop joint that differ in nature and properties, this connection of elements of prefabricated load-bearing systems undergoes a complex stress state during an emergency. The purpose of the work is to determine the stress-strain state of the loop joint of wall panels during progressive collapse. The objectives of the study are: determination of maximum stresses in the elements of a large-panel building with progressive collapse; numerical modeling of a loop joint and analysis of its stress-strain state; development of structural solutions for the joint, taking into account the identified features of its operation. Results. The maximum efforts in the panels and joints of the modernized structural solution of a large-panel building in case of emergency impact are determined, and options for upgrading the structural solutions of the loop joint are proposed. Multifactorial numerical modeling of the loop joint was carried out, taking into account the work on emergency impact, strength and deformation characteristics were determined. A solution has been proposed for the design of a loop joint for load-bearing systems, taking into account their operation during progressive collapse. Conclusions. The significance of the results obtained for the construction industry lies in the fact that the proposed option for the modernization of a typical solution and the results of the study can be used in the design of loop joints of large-panel buildings designed taking into account progressive collapse. |
