The bridge life was divided into 5 stages: bridge design, raw materials processing, construction, operation, and demolition.
Results show that major environmental impact appears during raw materials processing and construction.
Negative environmental impacts mainly show in the raw materials production stage, the construction stage and the abandonment stage, the fuzzy comprehensive evaluation scores of which are 40.03, 49.75 and 54.4.

Experimental Study on Damping Characteristics of Piezoceramic Materials Shunted by Passive Electrical Circuits Shaoze Yan 1, Fuxing Zhang 1 and Yangmin Li2 1 Dept.
Piezoelectric materials have an ability to efficiently transform mechanical energy to electric energy and vice versa, which makes them useful as structural dampers.
The principle of piezoelectric shunt is that piezoelectric materials can convert mechanical energy into electrical energy, and the electrical energy can be dissipated through a connected load resistance.
