Implementation of Thin-Walled Approximation to Evaluate Properties of Complex Steel Sections Using C++

Abstract

Steel sections have several applications in the construction industry. They are often used in the design and construction of huge industrial complexes. They also are used in transport, shipbuilding and packaging industries. Typical steel sections are used, and their properties have been recorded and are not needed to be calculated per application. They are recorded in most design software and used easily when required. This work focusses on using thin-walled approximation to calculate the section properties of complex sections which are a combination of existing section profiles. A program is written using C++ which would apply dimensions from the user and display the section properties at the end as result. The aim is to automate the process to calculate the required values and this would in turn save time. The values obtained from the program are compared with those calculated using existing formulas and the error obtained is reported.

Study of Wound-Healing Ointment Composition based on Highly Dispersed Zinc Oxide Modified with Nanoscale Silver

“…The area enclosed between the ascending and descending curve is called the hysteresis loop. The area of the hysteresis loop can be used to judge the mechanical stability of structured systems: the smaller it is, the more mechanically stable the system is [28,45].…”

“…The implementation of this work is related to our development -an ointment composition -which is a combined agent with antimicrobial properties (due to the content of nanosilver) and regenerative properties (due to the content of highly dispersed Zinc oxide). Zinc oxide, being a source of the essential trace element Zinc, locally affects the skin area, releasing Zinc ions that saturate damaged tissues and promote accelerated regeneration of damaged skin [11,[22][23][24][25][26][27][28][29]. The ointment composition well moisturizes the damaged skin with the simultaneous restoration of the epidermis.…”

Tackling Airborne Virus Threats in the Food Industry: A Proactive Approach

“…CDC recommendations are optional, and therefore may not be universally applied in different MPP facilities [ 12 ]. In addition, there are no CDC guidelines on additional and novel measures that are specific for food processing contexts [ 23 ] as current CDC guidelines appear to be drawn from the general knowledge of what is understood about infectious diseases, rather than specific guidelines based on AVT in an MPP context. For example, hand hygiene is the most effective way to prevent the spread of infectious diseases generally, yet the availability of this measure only offers limited protection from viruses such as COVID-19 that are spread by respiratory droplets [ 24 ].…”

Study of the effect of Baricitinib on the Course of COVID-19

“…There are works on the study of the venom activity of migalamorphic spiders [21], which concluded that the polypeptide combinations of the studied poisons have strong antiviral activity. The effect of other biologically active substances on antiviral activity has also been studied [22][23][24][25][26][27][28][29][30]. It is also worth noting the development of digitalization technologies [31][32][33][34][35].…”
