Abstract
In order to study a new reinforcement method for multilayer (4 layers) industrial building’s vibration, firstly, a new reinforcement method using a short‐pier shear wall was put forward. Secondly, an engineering example of a multilayer industrial building with abnormal vibration was introduced. A three‐dimensional finite element model of multilayer industrial building was established, and field vibration test was carried out. Test results showed that abnormal vibration of industrial building was caused by resonance between machines and multilayer industrial building. Finally, multilayer industrial building was reinforced by a new reinforcement method, and vibration experiment was carried out after reinforcement. The results show that the new reinforcement method has a good reinforcement effect. Strength and stiffness of multilayer industrial building were obviously improved, and natural frequency of industrial building in the length direction increased from 2.45 Hz to 5.87 Hz, natural frequency of industrial building in the width direction increased from 2.94 Hz to 7.83 Hz, frequencies of machines and frequencies of multilayer industrial building were not in resonance range, acceleration and velocity vibration characteristics of multilayer industrial building were improved, which can provide reference for the reinforcement of multilayer industrial building with a similar structural configuration.
Highlights
Multilayer industrial building is widely used in civil engineering, as it has a compact structural arrangement and can make full use of land resource
After multilayer industrial building was strengthened by a new reinforcement method, vibration characteristics of industrial building were tested again, and measuring point layout and working condition design were the same as those before reinforcement
Based on the vibration test results of a practical multilayer industrial building before reinforcement, a three-dimensional finite element model of industrial building was established, which has been bverified by tests
Summary
Multilayer industrial building is widely used in civil engineering, as it has a compact structural arrangement and can make full use of land resource. E actual damage of industrial buildings in various earthquakes is the destruction of reinforced concrete columns and nonstructural components, such as enclosure structural roofs. Adding various damping devices [15,16,17,18], adding reinforced concrete column [19], and adding steel beam [20] or steel support were commonly adopted methods in vibration attenuation engineering. There was a Advances in Civil Engineering method in which industrial building is connected with auxiliary buildings [21], which can increase overall stiffness to achieve the vibration reduction effect, but this method has great influence on the site when there was no affiliated building. Due to limitation of existing equipment and pipelines and other additional devices and space, selection of reinforcement methods were often limited, which often requires comprehensive consideration, and at this time, influence of reinforcement on the original structure and space should be minimized
