Standby Diesel Power Plant (SDG)
A standby diesel power plant (SDGS) is a rectangular building consisting of three cells with an identical space-planning solution.
The foundation of the SDGS building is a monolithic reinforced concrete slab.
The walls of the SDGF building are prefabricated monolithic reinforced concrete structures consisting of external prefabricated block cells and monolithic reinforced concrete filled between them.
The ceilings of the SDGF building are made of prefabricated monolithic in a non-removable formwork made of prefabricated ribbed shell slabs and monolithic.
The coating is also prefabricated monolithic slabs in a non-removable formwork made of prefabricated ribbed shell slabs.
The purpose of the calculation is to carry out the analysis for seismic effects.

Calculation model
The calculation model of the SDGF building was built in accordance with the formwork working drawings received from the Customer.
Reinforcement of the load-bearing structures of the reactor compartment building is set in accordance with the reinforcing working drawings.
Four-node and three-node plate finite elements were used to build the design model for the walls, floors, coating and foundation slab of the SDGF building. In the construction of steel beams and posts, rod finite elements were used.
Force boundary conditions on the structure of the RO building are set in accordance with the requirements of regulatory documents.
Kinematic boundary conditions are defined as a hinge fastening of the foundation slab nodes.
Calculation results
The calculation of the building of the backup diesel power plant for seismic effects is carried out in accordance with the requirements of NUREG/CR-0098, DBN V.1.1-12-201X, MT-T.0.03.326-13. The calculation is carried out by the linear-spectral method using the spectra of horizontal and vertical accelerations.
The natural frequencies and the corresponding oscillation shapes of the SDGF building were determined by the finite element method. The number of natural frequencies taken into account in the seismic action calculation was determined in accordance with the requirements of DBN V.1.1-12-201X.
As a result of the calculation, the maximum main tensile stresses and vertical displacements of the SDGS building, as well as its elements, were determined.

Loads on the SDGF building are accepted in accordance with the requirements of DBN V.1.2-2:2006, DBN V.1.1-12-201X, MT-T.0.03.326-13.
Seismic analysis is carried out in accordance with the requirements of DBN V.1.1-12-201X, MT-T.0.03.326-13.
The values of the strength characteristics of concrete and reinforcement were used, depending on the coefficient of working conditions, taking into account the features of the concrete and reinforcement in the structure. The coefficients of the working conditions of concrete and reinforcement are adopted on the basis of DSTU B V.2.6-156:2010.
The calculation took into account:
Constant loads
Own weight of load-bearing structures;The lateral pressure of the soil on the walls of the building is below the 0.000 mark.
Variable loads
1. Variable long-term loads
Weight of temporary partitionsStationary Equipment Weight
2. Variable short-term loads
Snow loadWind LoadCrane Load
3. Occasional loads
Episodic loads acting on SDGs include seismic impacts. The initial data for the calculation using the linear-spectral method are generalized response spectra (in this case, graphs of the dependence of the acceleration transmitted to the structure on the frequency of natural oscillations).
Load combinations for performing calculations for the first and second groups of limit states, as well as for calculating the HCLPF parameter (seismic boundary characteristic) are selected in accordance with the requirements of DBN V.1.2-2:2006, DBN V.1.1-12-201X, MT-T.0.03.326-13.

Verification of the limit states of the second group includes the calculation for the emergency combination, taking into account the operational design values of the loads.
