Time History Analysis of Earthquake Resistant Buildings with Placement of Rubber Damper between Bracing and Beams: Literature Studies

Introduction

Indonesia is a country that is highly vulnerable to earthquakes, which often causes significant damage to buildings, loss of lives, and material losses. The damage to buildings due to earthquakes can be prevented through strengthening structures specifically designed to deal with earthquake forces. However, many of the existing solutions often do not provide satisfying results. This is due to damage, both in structural and non-structural elements, is generally caused by significant differences in deviations. To overcome this problem, lateral reinforcement in buildings becomes important. However, this often causes an increase in earthquake force that works on the structure.

The Need for Alternative Solutions

Researchers have been looking for alternative solutions that are more effective and simple, namely by reducing earthquake energy to a level that does not endanger the structure of the building. In the context of the development of material technology, a damper device is found known as a rubber damper, which uses Lead Rubber Bearing (LRB) material. Earthquake resistant structural planning methods can be divided into two categories: conventional methods, which prioritize rigid structural forms and have high ductility, as well as technological methods that add earthquake damper devices to the structure.

The Role of Rubber Damper

Rubber Damper works by anticipating the energy produced by the earthquake through the deformation of the damper material, namely LRB. LRB is a type of damper consisting of a layer of rubber and steel, with tin core. The use of rubber damper in earthquake resistant structures has been studied extensively in recent years, and the results have shown that it can be an effective way to reduce earthquake energy. In this study, the nonlinear time history method was used with the help of SAP 2000 version 11 software to analyze the structure. With this method, data can be obtained about displacement, moment, latitude, and normal force.

The Analyzed Structure

The analyzed structure is a steel structure with an IWF profile, which is conventionally built with the addition of bracing and rubber damper. The structure is designed to withstand earthquake forces, and the rubber damper is placed between the bracing and the beams to reduce the energy produced by the earthquake. The results of the analysis showed that the use of rubber damper can reduce earthquake acceleration in buildings compared to structures without damper. Thus, differences in deviations between levels can be minimized and the safety of buildings can be increased.

The Results of the Analysis

As a result of the analysis, it was found that the use of rubber damper can reduce the moment by around 45.5%, the latitude of around 45.7%, and the normal force around 16.1% compared to conventional structures and structures that only use bracing. This shows that the placement of rubber damper between bracing and blocks not only increases building resistance to earthquakes, but also contributes significantly in reducing the force acting on the structure.

Conclusion

Thus, innovation in structural design using rubber damper is a positive step in reducing the risk of earthquake damage, especially in areas prone to earthquakes such as Indonesia. Through this approach, it is hoped that we can build buildings that are safer and resistant to natural disasters, and minimize the negative impacts that may be caused. The use of rubber damper in earthquake resistant structures has been shown to be an effective way to reduce earthquake energy, and it is hoped that this technology will be widely adopted in the future.

Based on the results of this study, it is recommended that the use of rubber damper be considered in the design of earthquake resistant structures. The placement of rubber damper between bracing and blocks has been shown to be an effective way to reduce earthquake energy, and it is hoped that this technology will be widely adopted in the future. Additionally, further research is needed to fully understand the effects of rubber damper on earthquake resistant structures, and to develop new technologies that can be used to reduce earthquake energy.

Finally, the study only considered the effects of rubber damper on earthquake resistant structures in a single location, and further research is needed to determine the effects of rubber damper on earthquake resistant structures in different locations.
