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...
Marine sponges inspire the next generation of skyscrapers and bridges（图）
Marine sponges next generation skyscrapers bridges
2020/10/10
When we think about sponges, we tend to think of something soft and squishy. But researchers at Harvard University are using the glassy skeletons of marine sponges as inspiration for the nex...
A University of Florida team is starting to gather real-time data on the impact of waves and rising water on bridges during hurricanes. Unlike studies that rely on tests in wave laboratories, this res...
New way for bridges to withstand earthquakes: support column design（图）
New way bridges withstand earthquakes support column design
2019/10/21
Bridges make travel faster and more convenient, but, in an earthquake, these structures are subject to forces that can cause extensive damage and make them unsafe.Now civil and environmental engineer ...
PERFORMANCE EVALUATION OF EXISTING STEEL AND CONCRETE GIRDER BRIDGES THROUGH NON-DESTRUCTIVE LIVE-LOAD TESTING
EXISTING STEEL CONCRETE GIRDER BRIDGES NON-DESTRUCTIVE LIVE-LOAD TESTING
2014/10/22
Traditional evaluations of a bridge behavior are based upon assumptions of material properties, load distributions in the bridge deck, any quantified structural damage from visual inspections, and the...
Dynamic Analysis of Suspension Bridges and Full Scale Testing
Suspension Bridges Dynamic Analysis Tangent Stiffness Cable Structures Bridge Testing
2013/1/31
This paper is concerned with the earthquake analysis of suspension bridges, in which the effects of large deflections are taken into account. The first part of the study deals with an iteration scheme...
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...
DAMAGE OF BRIDGES RESULTING FROM FAULT RUPTURE IN THE 1999 KOCAELI AND DUZCE, TURKEY EARTHQUAKES AND THE 1999 CHI-CHI, TAIWAN EARTHQUAKE
seismic damage bridge fault rupture Turkey Kocaeli Earthquake
2009/1/6
This paper describes the damage of bridges resulting from the fault movements in the 1999 Kocaeli and Duzce, Turkey, Earthquakes and the 1999 Chi-Chi, Taiwan, Earthquake. Effect of the fault displace...
ON QUANTIFICATION OF USER COSTS OF BRIDGES IN HOKKAIDO AND THEIR APPLICATIONS
user cost bridge management system life-cycle cost maintenance system
2009/1/5
In this paper, the effect of the user cost (UC) on the life cycle cost (LCC) of bridges in Hokkaido will be clarified by numeric conversion. The idea of reducing LCC will be incorporated to create an...
