In recent years, carbon fiber reinforced polymer (CFRP) has been widely used in bridge repair, retrofitting, rehabilitation and strengthening to improve the bearing capacity. Although many studies have conducted explore efficiencies of CFRP, test specimens were small results difficult apply full-scale bridges. Investigations into effects CFRP on real life structures rely field load tests (witho...

This paper presents a novel application of circular domain features calculation based condition monitoring method for low rotational speed slewing bearing. The method employs data reduction process using piecewise aggregate approximation (PAA) to detect frequency alteration in the bearing signal when the fault occurs. From the processed data, circular domain features such as circular mean, circ...

Purpose: The aim of this work is the construction bridge structures on a soil foundation with physical and mechanical characteristics, often differing from survey activity parameters. Technical regulations supports envisage plate-bearing test drilled pile foot. Design/methodology/approach: quality improvement not only preparation, but also requirements for structural reliability, approximated R...

Abstract This research concerns the use of warped ruled surfaces in load bearing structures 19th century stone bridges Prague. The descriptions a skew arch used at Negrelli Viaduct and special surface called “corne de vache” Legion Bridge are based not only on historical survey, archival materials period publications, but also contemporary measurements.
