This work is dedicated to constructing a multi-scale structural health monitoring system to monitor and evaluate the serviceability of bridges based on the Hadoop Ecosystem (MS-SHM-Hadoop). By taking the advantages of the fault-tolerant distributed file system called the Hadoop Distributed File System (HDFS) and high-performance parallel data processing engine called MapReduce programming parad...

For the purpose of splicing widening bridges without interrupting traffic in expressway reconstruction and extension projects, different types anti-differential disturbance concrete (ADC) were developed. This paper experimentally investigated mechanical performance ADC under influence traffic–vehicle coupling vibration. The experimental device, with one end fixed other vertically vibrated, was ...

We show if the flow polynomial of a bridgeless graph G has only integral roots, then G is the dual graph to a planar chordal graph. We also show that for 3-connected cubic graphs, the same conclusion holds under the weaker hypothesis that it has only real flow roots. Expressed in the language of matroid theory, this result says that the cographic matroids with only integral characteristic roots...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

Homeland security requires thorough monitoring of the nation’s transportation infrastructure health. Discussed in this paper is research aimed at developing a smart wireless sensor network that is an efficient and practical health monitoring system and is also versatile for security monitoring strategies. At the core of such a system is an integrated network which collects data from a variety o...

Amde Department of Civil and Environmental Engineering This research includes parametric studies performed with the use of three-dimensional nonlinear finite element models in order to investigate the effects...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...
