1. Application of rubber shock-absorbing products in construction projects

Modern cities are home to a rising number of high-rise structures, which raises the bar for earthquake resilience and vibration reduction in construction projects. In light of this, rubber shock-absorbing devices have found widespread application in the field of construction engineering because of their superior isolation and vibration-reduction capabilities.

1.1 Principles and advantages of vibration reduction and isolation

Rubber material has high elasticity and good damping properties, which can effectively absorb and consume vibration energy. Applying rubber products to building structures can reduce vibration response and improve seismic performance. The principle of this vibration reduction and isolation technology is to use the deformation characteristics of rubber products to disperse and consume vibration energy, thereby reducing the amplitude response of the building under dynamic loads. Compared with traditional rigid supports, the use of rubber shock-absorbing products can not only improve the seismic performance of buildings, but also effectively reduce vibration and noise in the indoor environment and extend the service life of buildings and equipment.

1.2 Common types of rubber shock-absorbing products

In construction projects, common rubber shock-absorbing products mainly include the following three types:

Rubber bearing

The rubber bearing supports the building’s gravitational load as a shock-absorbing mechanism. It is made up of a steel plate and a rubber layer. Rubber bearings are known for their great compressive bearing capacity, superior fatigue resistance, a·nd controlled stiffness. They are extensively utilized in load-bearing constructions like high-rise buildings and bridges. Rubber bearings may be categorized into three types based on their internal structures: high damping rubber bearings, lead rubber bearings, and steel core rubber bearings.
