In modern construction, steel trusses remain one of the most common types of load-bearing structures used in the construction of industrial, civil, and public buildings. Their use is driven by high load-carrying capacity...

The paper presents a methodology and an example of determining the floor response spectrum of nuclear power plant building structures under earthquake loads. When critical energy infrastructure facilities are consider...

Conjugate gradient method (CGM) is one of the most efficient numerical methods for solving unconstrained optimization problems. It is also known as an iterative method with simple formulation. The classical CGM has alway...

This article presents the results of a numerical study on the performance of various configurations of lightweight monolithic slabs of the BubbleDeck system, which use hollow plastic ball inserts to eliminate inefficient...

We propose and validate a method for designing a broadband variable beamsplitter using a metamaterial with subwavelength thickness. Through theoretical analysis and numerical simulations, we demonstrate that the reflecta...
