Comparative Study on the Applicability of Analytical and Experimental Methods in the Analysis of the Safe Use of Rail Tankers Carrying Petroleum Products Under Pressure

Abstract

The safety of railways has been and remains a critical topic. Whether it is infrastructure or rolling stock, the issue of safety is a permanent concern of the utmost importance, being reflected in the efficiency of any transport system. This paper focuses on the safety in operation of pressure vessels that equip railway tanks. There are many articles and works on this subject, and it is well-known that there are both national and international regulations regarding their design, execution, operation and maintenance. Also, there are quite a few reports on the BLEVE (Boiling Liquid Expanding Vapour Explosion) phenomenon resulting in material damage and significant casualties. The BLEVE-type explosion is not considered a chemical explosion derived from a gas-air explosive environment (also present in non-flammable gases), but rather a mechanical explosion through over-pressurization. Thus, we propose a comparative study between the results obtained using theoretical methods and those obtained as a result of tensoresistive measurements on such a tanker.

The Use of Damper Systems in Buildings With Reinforced Concrete Structures

“…The purpose of consolidation is to impose a favorable structural mechanism of energy dissipationin this case, the expansion of plastic areas at the beam end areas and at the pillar basis. Another purpose is to increase the lateral resistance, the rigidity and plastic deformation capacity of the structural elements and of the structure assembly (Florescu et al,2018). The P100-3:2008 standard, Code for the assessment and design of consolidation works for seismically vulnerable existing buildings, vol.…”
