The Effectiveness of the CST Element Due to a High Beam Centered Load

Introduction

High beams, also known as Deep Beams, are a crucial component in various structures, including transfer beams in tall buildings, turbine generator support structures, and foundation walls. These beams are designed to withstand heavy loads, which are then forwarded to the support through the push of compressive force. The behavior of high beams, influenced by geometry in particular, is a problem of plane stress. In this study, we will explore the effectiveness of the CST (Constant-Strain Triangle Element) element in predicting the behavior of high beams under centralized loads.

Understanding High Beams

High beams are beams with a relatively large height compared to the span. They are designed to withstand heavy loads, which are then forwarded to the support through the push of compressive force. This push is a combination of the outer load and the reaction force. High beams are commonly found in structures such as transfer beams in tall buildings, turbine generator support structures, other infrastructure buildings, and even on foundation walls, stake hats, and shear walls.

Behavioral Analysis of High Beams

The behavioral analysis of high beams can be done using various methods, including photoelastic methods, element methods (finite element method), or the theory of 2-dimensional elasticity. Among these three methods, the element method has become a popular choice because of its ability to handle complex geometry and various burdens. The element method is a numerical method that divides the structure into a number of small elements. Each element has certain mechanical properties which are then analyzed to determine the overall behavior of the structure.

The CST Element

One of the basic elements in the 2-dimensional element method is the CST (Constant-Strain Triangle Element) element. This element is triangular and has advantages because it is simple and easy to apply. The CST element is a popular choice in finite element analysis because of its ability to provide accurate results with a relatively small number of elements.

Applying CST Elements to High Beams

In this study, CST elements will be applied to high beams using CST programs to analyze their effectiveness in predicting block behavior. The cantilever beam is chosen as a test model because this structure is easily modeled and analyzed. The cantilever beam with the ratio of L = 3D (the length of the beam 3 times the height of the beam) will be used to see the effectiveness of the convergence of a number of CST elements to the exact solution. This convergence is known as the "Weak Patch Test", which tests the ability of elements to predict accurate solutions with an increase in the number of elements.

Optimization of the Element Method

The optimization of the element method depends on the development of effective element models. Computers play an important role in this process because it allows the development of complex models and accurate analysis. By selecting the right elements, such as the CST element in this case, and with the help of a computer, the method of elements can provide relevant and accurate results for various structural problems, including high beams.

The Importance of Accurate Analysis

Accurate analysis is crucial in structural engineering because it can help prevent structural failures and ensure the safety of people and property. The CST element is a popular choice in finite element analysis because of its ability to provide accurate results with a relatively small number of elements. By applying CST elements to high beams, engineers can gain a better understanding of the behavior of these structures and make informed decisions about their design and construction.

Conclusion

In conclusion, the CST element is a powerful tool in finite element analysis, particularly when applied to high beams. The CST element is simple and easy to apply, making it a popular choice among engineers. By applying CST elements to high beams, engineers can gain a better understanding of the behavior of these structures and make informed decisions about their design and construction. The optimization of the element method depends on the development of effective element models, and computers play an important role in this process.

Recommendations for Future Research

Future research should focus on the development of more accurate and efficient element models, such as the CST element. Additionally, researchers should explore the application of CST elements to other types of structures, such as bridges and buildings. By continuing to develop and refine the element method, engineers can gain a better understanding of the behavior of complex structures and make informed decisions about their design and construction.

Limitations of the Study

This study has several limitations. Firstly, the study only focuses on the CST element and does not explore other types of elements, such as the quadrilateral element. Secondly, the study only applies the CST element to high beams and does not explore its application to other types of structures. Finally, the study only uses a simple cantilever beam as a test model and does not explore more complex structures.
