Our company is Changzhou Road Structure Damping Equipment Co., Ltd.

Traditional structural seismic resistance is to resist natural disasters, such as earthquake, wind, snow, tsunami, etc., by strengthening earthquake resistant behavior (intensity, stiffness and ductility) of the structure itself. Due to the uncertainty of natural calamities' strength and features, the structures devised by traditional quake-proof methods do not have self adjusting ability. Therefore, they tend to result in great economic losses and casualties when earthquake is forthcoming.

The development and application of viscous dampers equal to erecting "Safety Air-bags" on buildings or bridges. When earthquake is approaching, dampers furthest absorb and consume the impact energy of earthquake to building structures, greatly alleviating the impact and destruction of earthquake to building structures.

Our JZN series viscous dampers are passive velocity-dependent ones devised and manufactured based on the principle that interaction between viscous media and structural components of dampers are applied to generate damping force. The medium used is silicone oil. Such medium has the following features: small viscosity-temperature coefficient, stable performance at over low and high temperatures (-50~+250 Degrees C) and greater radiance resistant performance. Meanwhile, the medium has excellent electric insulation property and great ozone resistant, corona resistant, water-repellent and moisture resistant performances.

According to relevant codes, such as JG/T209-2007 "Dampers for Vibration Energy Dissipation of Buildings", our company independently developed and produced JZN series viscous dampers on the basis of digesting and absorbing congeneric products at home and abroad, with our own patent. Additionally, by appraisal of the third-party authorities, each performance index of our products reaches the technological level of congeneric products at home and abroad.
