Bridges with limb-inspired architecture can withstand earthquakes, cutting repair costs（图）
Bridges limb-inspired architecture withstand earthquakes cutting repair costs
2020/11/6
Structural damage to any of the nation's ailing bridges can come with a hefty price of billions of dollars in repairs. New bridge designs promise more damage-resistant structures and, consequently, lo...
Seismic design force for single-span slab-girder skewed bridges
Skewed bridge slab-girder seismic analysis cross-frame elastomeric bearing
2009/2/20
This paper investigates the validity of seismic design force recommended by AASHTO for single-span bridges. The prescribed force is equal to the products of soil factor , acceleration and tributary we...
Seismic behavior of isolated bridges: A-state-of-the-art review
Bridge seismic base isolation
2009/2/19
An update state-of-the-art-review of the behaviour of isolated bridges to seismic excitation is presented. The review includes the literature on theoretical aspects of seismic isolation, parametric be...
Analysis and shape optimization of variable thickness box girder bridges in curved platform
Department of Civil Engineering, University of Gaziantep
2009/2/19
This paper deals with the development of reliable and efficient computational tools to analyze and find optimum shapes of box girder bridges in curved platform in which the strain energy or the weight...
Local Government in Australia is responsible for the operational management and maintenance of over 20,000 bridges. More than 70% of these bridges comprise aging timber bridges, the load capacity and ...
In design of conventional bridges the gap between bridge spans is usually only a few centimetres. For such an expansion joint poundings between adjacent bridge girders during strong earthquake shaking...
