In order to control the tower deviation in cable hoisting process of long-span concrete-filled steel tubular arch bridge during construction monitoring, a practical method correction was studied and established. paper, based on studies about error formation mechanism lifting, relevant formulas rib elevation changes caused by change state were deduced. The traditional methods including increase ...

A framework of integrated expert systems based on fuzzy Petri net, called fuzzy Petri net based expert system (FPNES) are proposed for bridge damage assessment. Major features of FPNES include: reasoning for uncertain and imprecise information; knowledge representation through the use of hierarchical fuzzy Petri nets; reasoning mechanism based on fuzzy Petri nets; and explanation of reasoning p...

today, expert systems are widely applied in medicine for prognosis, diagnosis, checkup, and treatment of various kinds of diseases. a comprehensive system for the checkup and treatment of different types of diabetes is still lacking. this paper reports development of such a system, its validation, and its utility in facilitating medical decision-making and supporting self-care.

Sensitivity analysis of the early-age properties of high-performance concrete – a case study on bridge barrier walls

15. Supplementary Notes Supported by a grant from the U.S. Department of Transportation, University Transportation Centers Program 16. Abstract Inspections of bridge substructures in Texas identified surface deterioration of reinforced concrete columns on bridges continuously exposed water. Initial hypothesis were that the surface deterioration was a result of the acidity of the water in which ...

The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) B...

An assessment of newly reconstructed reinforced concrete barrier walls on a highway bridge near Montreal indicated intense transverse cracking only a few days after concreting. Subsequent inspection of other concrete bridges in urban areas confirmed that such cracking is not uncommon. Analytical models, together with field and estimated data, were used to study the magnitude and roles of the fa...
