“…Chattopadhyay et al (2007) conducted experiments on elbows (TWC) 200-400 mm in diameter with circular cracks, subjected to bending loading. Liamani, S et al (2021) analyzed the presence of a horizontal crack in an HDPE pipe using finite element analysis (FEA) under patch-corrected internal loading. FEA is a computational method employed to simulate and analyze the behavior of structures.…”

The introduction of pressure piping increasingly requires the use of efficient materials which must withstand both high hydrostatic pressures, high mechanical loads and high thermal gradients. At nuclear power plants, piping systems are subjected to high pressures (up to 60 MPa). The occurrence of cracks and their possible spread is one of the serious risks in the industry. For this reason, elbows are considered critical components of a piping system. Therefore, in order to design and/or qualify a pipe structurally, it is useful to have a reliable evaluation of their structural behavior under different combined loads. The objective of this study is to determine analytical functions for the evaluation of the J integral as a function of crack size, elbow size, and the nature and intensity of loading. This assessment is derived from the numerical results obtained by the WARP3D calculation code exploiting the finite element method (FEM).

The article describes how to transform the time-consuming process of selecting design solutions for parking spaces according to regulatory requirements and terms of reference by building information modelling (BIM). The main purpose of the work is to determine the possibility of applying a generative approach to the parking lot design by creating an optimization model of variant design. The process of selecting design solutions for parking is considered by using mathematical modeling and multi-criteria optimization. A mathematical description of finding the optimal solution on the region of admissible ratios is obtained both between the two types of parking spaces required by regulatory documents (type 1-Standard, with dimensions of 5.3 × 2.5 meters; type 2 - for People with Limited Mobility (PLM), with dimensions of 6.0 × 3.6 meters) and between the occupied area and the total number of parking spaces. The optimization model of choosing design solutions for parking lot helps a design engineer to adapt changes in requirements for defining admissible options for space-planning solutions. The study proves that the task of choosing admissible and optimal solutions for the parking lot, depending on the set of conditions, can be performed by using algorithms, and, consequently, by using computer-aided design in BIM. The proposed approach to parking lot design allows the project organization to coordinate the initial conditions and solutions between the project participants and related departments, and also serves as the basis for solving subsequent design tasks, such as determining the economic efficiency, the safety of the parking project, and others.
