Structural analysis is a key part of engineering, especially in structural analysis and mechanics. Correctly performed strength calculations ensure that structures can withstand the loads placed on them and operate safely throughout their design life. In this article, we will go through how to perform strength calculations correctly.
What is a strength calculation?
Strength calculation is an engineering analysis used to determine the resistance of structures and materials under different loading conditions. It is an essential part of mechanics and structural analysis, and aims to ensure that structures can withstand the loads placed on them without damage or failure.
Strength calculations cover a wide range of analyses, including stress analyses, deformation analyses and stability analyses. These analyses can be used to predict how structures will behave under different loading conditions and ensure that they meet safety and performance requirements.
In engineering, strength calculations are an essential tool to help design durable and safe structures. It is particularly important in the construction industry, where the safety and durability of structures are of paramount importance.
Steps in the strength calculation
A strength of field calculation always starts with a precise definition of what you want to analyse. This includes the geometry of the structure, material properties and loading conditions. It is important that all input data is as accurate and comprehensive as possible to ensure that the calculation results are reliable.
The next step is the calculation itself, which may include various analyses and simulations. This step often requires specialised software and tools that allow complex calculations to be carried out efficiently and accurately. During the calculation, the stresses, deformations and other critical factors of the structure are considered.
Finally, the results are analysed and interpreted. This step is as important as the calculation itself, as the results are used to make decisions on the design of the structure and any changes. It is important that the results are presented in a clear and understandable way so that all parties involved can make informed decisions.
Main tools and software
A wide range of tools and software are used to perform strength calculations. One of the most common is the Finite Element Method (FEM), which allows complex structures to be analysed by breaking them down into small parts, or elements. FEM software such as ANSYS, Abaqus and SolidWorks Simulation are widely used in engineering.
In addition, various CAD software such as AutoCAD and SolidWorks are used to facilitate the modelling and preparation of structures for strength calculations. These software programs allow the creation of accurate 3D models, which is essential for accurate calculations.
Traditional calculation tools, such as Excel and various spreadsheets, are also still in use, especially for simpler calculations. These tools allow basic calculations and checks to be carried out quickly and efficiently.
The importance of strength calculation in the construction sector
In the construction industry, strength calculation is a key part of the design process. It ensures that structures can withstand the loads placed on them and operate safely throughout their design life. This is particularly important in large and complex construction projects where the safety and durability of structures are of paramount importance.
Strength calculations also help to optimise the design of structures and the use of materials. This can lead to significant cost savings and improved structural performance. Optimised design can also reduce material waste and improve the efficiency of the construction process.
Companies like Hefmec that offer expert strength calculation services can help their customers ensure that their structures are safe, durable and cost-effective. For example, when designing lifting equipment, strength calculations are essential to ensure that the equipment can withstand the loads placed on it and operate safely in all operating conditions.
A properly performed strength calculation is therefore an essential part of civil engineering. It ensures the safety and durability of structures, optimises design and improves the efficiency of the construction process.
