Feb 27, 2025 by ADMIN 90 views

Introduction

In the world of building construction, elements such as blocks, columns, and plates are inevitable to integrate in a sturdy and functional structure. This element can be made of various materials, including steel, wood, and concrete. In certain construction projects, it is very important to plan an effective connection between these elements. The nature of the connection is very dependent on the type and construction of the connection itself. Connections can vary, ranging from rigid connections to semi-nail or semirigid connections. In this context, the connection analysis between concrete and steel structures is very relevant, especially when the connection is not perfect rigid.

Importance of Connection Planning

Construction design and design procedures are a crucial factor in this connection planning. The advantages and disadvantages of the material used, such as steel, must also be considered carefully. Steel as a construction material has a number of advantages, including high strength and good durability. However, steel also has several weaknesses, such as vulnerable to corrosion and temperature instability. Therefore, knowledge of the mechanical properties and types of structural steel commonly used is the key in planning a connection.

Types of Connections

Connections can vary, ranging from rigid connections to semi-nail or semirigid connections. Rigid connections provide a fixed connection between two elements, while semi-nail or semirigid connections provide a flexible connection. In this analysis, the focus is on semirigid connections, which provide sufficient levels of flexibility, making it easier to adapt structure to loads and deformations that may occur due to gravitational loads or lateral loads such as wind or earthquakes.

Semirigid Connections

Semirigid connections in the construction structure have unique characteristics that distinguish them from rigid connections and free connections. This connection provides sufficient levels of flexibility, making it easier to adapt structure to loads and deformations that may occur due to gravitational loads or lateral loads such as wind or earthquakes. The main advantage of the Semirigid connection is its ability to distribute moments and styles more efficiently throughout the structure.

Analysis of Concrete and Steel Structure Connection

In this analysis, building modeling consists of three-storey concrete structures that are connected with a two-storey steel structure. The planned connection between the concrete column and the steel column is the Semirigid connection, where the percentage of release to be compared is 20%, 40%, 60%, and 80%. The analysis will be carried out to observe the inner-force forces and their impact on the basic building due to changes in the percentage of release.

Methodology

The analysis will be carried out using SAP 2000 software, which is a powerful tool for structural analysis and design. The software will be used to model the building and simulate the loads and deformations that may occur due to gravitational loads or lateral loads such as wind or earthquakes. The results of the analysis will be used to determine the inner-force forces and their impact on the basic building due to changes in the percentage of release.

Results

Based on the results of the analysis using SAP 2000 software and the graphics that have been produced-which include frame 16, frame 18, frame 20, and frame 22-can be concluded that the moment on the semirigid connection has a significant influence, especially at the connections between concrete columns (buildings basic) and steel columns (enhancer building). Conversely, the latitude and normal force does not show a significant effect on this connection.

Conclusion

In conclusion, the connection analysis between concrete and steel structures is very important in construction planning. Using Semirigid connections can provide benefits in terms of load efficiency and structural response. Therefore, a deep understanding of the characteristics of this connection will be very helpful in creating a safe, strong, and durable structure.

Recommendations

Based on the results of this analysis, the following recommendations can be made:

The use of Semirigid connections in concrete and steel structure connections can provide benefits in terms of load efficiency and structural response.
A deep understanding of the characteristics of this connection is necessary to create a safe, strong, and durable structure.
The percentage of release in Semirigid connections should be carefully considered to ensure that the connection can adapt to changes in load.

Future Research Directions

This analysis has provided valuable insights into the connection analysis between concrete and steel structures. However, there are still many areas that require further research. Some of the future research directions include:

Investigating the effects of different types of loads on the Semirigid connection.
Developing new design methods for Semirigid connections.

Introduction

In our previous article, we discussed the importance of connection planning in building construction, particularly in the context of concrete and steel structure connections.

Q: What is the significance of connection planning in building construction?

A: Connection planning is a crucial aspect of building construction, as it determines the strength and stability of the structure. A well-planned connection can ensure that the structure can withstand various loads and deformations, while a poorly planned connection can lead to structural failures and safety risks.

Q: How does the percentage of release in semirigid connections affect the structure?

A: The percentage of release in semirigid connections can significantly impact the structure. A higher percentage of release can provide more flexibility and adaptability to changes in load, while a lower percentage of release can lead to increased stiffness and reduced flexibility.
