Highway Bridge Vibration Studies
IN T R O D U C T IO N T h e goal of the bridge engineer is to design econom ical structures w hich are safe, du rab le , and serviceable. D eterm in ing the dynam ic response of bridges has been the topic of num erous studies in recent years. M uch a tten tion has been focused on m axim um dynam ic d isp lace m ents an d m om ents and on the d istribu tion of loads to the floor system —inform ...
متن کاملGraphical 3D Visualization of Highway Bridge Ratings
Aging highway infrastructure requires effective rating methodologies to prioritize bridges for rehabilitation and repair. To aid engineers in decision making regarding bridge maintenance, a three-dimensional 3D visualization system is developed for rating reinforced concrete deck-girder bridge. Color codings show the most probable mode of failure for girder cross sections under combined moment-...
متن کاملEvaluation of Highway Bridge Strength Considering Parapets
This paper describes a study evaluating increase in design strength, performance and capacity when including bridge parapets in a bridge analytical model. Traditionally, concrete parapets are treated solely as superimposed dead load in an overall bridge structural design. Parapets are detailed from a safety standpoint to resist impact forces from vehicle loading. However, in the global design m...
متن کاملFirst Smart Highway Bridge in Canada
The Beddington Trail/Centre Street, Calgary, Alberta, Canada, is the first prestressed concrete highway bridge built in Canada pretensioned by Carbon Fiber Reinforced Plastic, FRP, tendons. It is also the first bridge which has utilized a structurally integrated optical sensors system to monitor the behaviour. The bridge is completed and was opened to traffic on November 5, 1993. The project in...
متن کاملSeismic Vulnerability Study of the Us Highway Bridge Systems
In the fall of 1998, the Federal Highway Administration of the U.S. Department of Transportation initiated a series of studies related to the seismic performance of the U.S. national highway system. The research conducted under this study is intended to provide improved tools for evaluating and assessing the social costs and impacts of earthquakes on highway systems and bridges, and to reduce t...
