[1] Belelubsky personally designed and managed over 100 projects, including the steel railway bridges across the rivers Don, Danube, Volga, Ob, Kama, Oka, Neva, Irtysh, Belaya, Ufa, Neman, Berezina and many others.

In 1875, Belelubsky designed the Alexander Railway Bridge in cooperation with Vladimir Ilyich Berezin and Konstantin Yakovlevich Mikhailovsky.

Working on the project, Belelubsky developed a method for analysis of clear headrooms for large bridges, which later came to be widely acknowledged.

The bridge provided a critical link between Central Russia and Volga region, allowing to continue the construction of the Trans-Siberian Railway further east, toward Siberia and Turkestan.

His breakthrough allowed him to successfully replace wrought iron with steel in constructing bridges along the four major sections of the Trans-Siberian Railway.

This innovative technique involved integrating articulated support for the cross beams of the travel surface directly into the lower chords of trusses within the bridge spans.

By doing so, the structural integrity and operational efficiency of the bridge were greatly improved, as it effectively lessened the pressure on the truss components.

The system's functional features captured immediate attention, eventually earning global recognition as the "Russian type of structural support".

This remarkable structure featured striking open truss bridge girders that stretched an impressive length of 160 metres (520 ft).

[7] Belelyubsky played a crucial role in advancing Russian science and served as a representative for his country at numerous international exhibitions and forums.

Additionally, he was granted honorary memberships in the Architekten- und Ingenieur-Verein zu Berlin in 1909 and the French Society of Civil Engineers.

Belelubsky was highly regarded by those who lived during his time due to his refined cultural tastes and profound spiritual outlook.

Belelyubsky was actively involved in significant educational initiatives aimed at providing training for railway engineers across the country.

Notably, his captivating lectures on Structural Mechanics, published in 1885, quickly gained widespread recognition and became the go-to textbook for students and a valuable resource for numerous engineers in the field.

However, it is crucial to bear in mind that you will be responsible for overseeing your own construction projects, as you will be working on behalf of the state and serving the needs of the public.

In order to truly be considered an engineer and master of their craft, you must undertake the task of building with efficiency, care, frugality, solidity, and creativity.
