ACCOUNT THE INFLUENCE OF DEFORMATIONS FROM PART-TIME WORK OF THE TERRITORY ON THE STRESS-STRAIN STATE OF BUILDING STRUCTURES

Abstract

The paper considers the possibility of taking into account the deformations from the part-time work of the territory when calculating buildings in the LIRA-SAPR. The parameters of part-time work deformation have been considered and analysed. The calculation diagrams have been drawn up which take into account the additional deformations of the part-time work at the nodes at the base level of the calculation diagram in addition to the deformations of the ground settlement. Two fundamentally different computational schemes are considered - frame buildings on freestanding columnar foundations and buildings on strip or slab foundations. Calculation algorithms for these schemes for the LIRA-SAPR software package are compiled. The description of calculation schemes operation is given. Difficulties that arise when solving the task are analysed. The results of solving test tasks are given. Transformation of the computational scheme according to the developed algorithm is performed, and results of calculations for the convex and concave forms of undercutting are presented. The calculation results showed that the proposed model of calculating buildings taking into account part-time work.
