Abstract

The invention discloses a green shock and vibration absorbing bridge tower which comprises a conventional bridge tower, a tuned mass damper (TMD) system and a tuned liquid damper (TLD) control system. The shock and vibration absorbing technology is combined with the environmental protection concept; green plant accommodation boxes are used as mass blocks of TMDs and connected with the surface of the structure through shock and vibration isolating rubber gaskets; and water tanks are used as mass blocks of TLDs and connected with the top of the bridge tower. The TMDs and the TLDs are used to reduce the shock and vibration response of the upper part of a bridge tower under a variety of excitation in all directions in the horizontal plane and beautify the ornamental environment of the top of the bridge tower through the damping, energy consuming and shock and vibration absorbing functions of the shock-isolating rubber gasket. In addition, vertical shock-absorbing bolts are arranged to limit the vertical displacement of the shock and vibration isolating rubber gaskets and enhance the vertical energy consumption. The green shock and vibration absorbing bridge tower disclosed by the invention adopts a simple design, has low manufacturing cost, has a wide engineering application prospect along with the continuous improvement of the attention paid to the shock-absorbing design of the long-span bridge tower and can bring significant economic and social benefits.

Description

technical field

[0001] The invention relates to a green shock-absorbing and vibration-absorbing bridge tower with a shock-absorbing (vibration) function, which is especially suitable for use in large-scale bridges such as long-span cable-stayed bridges and suspension bridges, and uses green and environmentally friendly means to reduce the impact of earthquakes on bridge tower structures. The vibration response under the action of wind, vehicle, etc. Background technique

[0002] Earthquakes and wind disasters are common natural disasters, causing huge casualties and economic losses. In recent years, earthquake disasters have occurred continuously. The 2008 Wenchuan earthquake in my country caused 69,227 deaths and 374,643 injuries, and the 2010 Yushu Qinghai earthquake caused 2,698 deaths. Among them, the damage and collapse of civil engineering structures is one of the main causes of economic losses and casualties. At the same time, the global climate has also changed gre...
