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 ...

In this paper the parametric study is carried out to investigate the effect of number of cells in optimal cost of the non-prismatic reinforced concrete (RC) box girder bridges. The variables are geometry of cross section, tapered length, concrete strength and reinforcement of the box girders and slabs that are obtained using ECBO metaheuristic algorithm. The design is based on AASHTO standard s...

Infrastructures are a key factor for economy. Among them, transportation infrastructures are vital for human life and economy. And within the transportation networks, bridges are key elements for connecting people anddelivering goods. For this reason, bridges have been built sincemany centuries ago, in some way, and the advances (and sometimes geographical expansions!!) of ancient cultures all ...

We present a cognitive model that bridges work in analogy and category learning. The model, Building Relations through Instance Driven Gradient Error Shifting (BRIDGES), extends ALCOVE, an exemplar-based connectionist model of human category learning (Kruschke, 1992). Unlike ALCOVE which is limited to featural or spatial representations, BRIDGES can appreciate analogical relationships between s...

Ultrasonic propagation velocity across wood fiber direction was measured in wooden bridges in order to investigate the possibility of nondestructive deterioration diagnosis of wooden bridges. The measurements were carried out for three different types of wooden bridges. The periodical measurement was also made for one of them to investigate its secular change. The results were : (1) The histogr...

We have examined extended structures, bridges and arches, in computer generated, nonsequentially stabilized, hard sphere deposits. The bridges and arches have well defined distributions of sizes and shapes. The distribution functions reflect the contraints associated with hard particle packing and the details of the restructuring process. A subpopulation of string-like bridges has been identifi...

displacement coefficient method (dcm) stipulated in the asce 41-06 standard is becoming the preferred method for seismic rehabilitation of buildings in many high-seismic-hazard countries. applications of the method for non-building constructions such as bridges are beyond the scope of this standard. thus its application to this kind of structure should be approached with care. target displaceme...

D uring the past decade, there has been a burgeoning interest in the role of religiosity in family functioning and child and adolescent adjustment (e.g., bridges & moore, 2002; mahoney, Pargament, swank, & Tarakeshwar, 2001) and as a resource for adults coping with stress (Pargament, 1997, 2007). The focus of this chapter is on the role of religiosity across the life span in predicting adulthoo...

We calculate improved lower bounds for the connective constants for selfavoiding walks on the square, hexagonal, triangular, (4.8), and (3.12) lattices. The bound is found by Kesten’s method of irreducible bridges. This involves using transfermatrix techniques to exactly enumerate the number of bridges of a given span to very many steps. Upper bounds are obtained from recent exact enumeration d...
