Quasi-static and dynamic damage mechanisms in alumina tiles were investigated. The tiles were under a variety of boundary conditions at the tile's edges during impact NATO 0.3 cal. AP rounds with hardened and sharpened steel core were used. The alumina tile samples were 50x50 mm2 area, the thicknesses ranging from 5 to 12 mm. 'he tiles were mounted in a special confinement frame, which enabled ...

The current work presents a unique study on the seismic performance of innovative corrugated-plate steel bridge piers. While several previous research was conducted tubes with cross sections such as rounded or semi triangular plates, structural members straight ribbed corrugation geometry under uniaxial cyclic loading remained gap. Thus, this aims to present new concept that could add promising...

Girders with corrugated steel web are preferred and widely used in recently constructed bridges industrial buildings. Sandwich core girders by adding two plates (skins) to the web. This study aims investigate shear span-to-depth ratio impact on performance of sandwich Three ratios (a/d): 1.0, 1.833 2.5, were examined. The test includes three thickness 30 mm, 60 mm thickness, conventional flat w...

In moment resisting reinforced concrete framed buildings, corner joints are found at the roof level. These joints, if designed for gravity loads and are based on pre-seismic codes, may suffer substantial damage during earthquakes particularly under opening cycles, i.e. those causing flexural tension on the inside of the joint. Several techniques of repair and strengthening of reinforced concret...

At BAM, the Federal Institute for Materials Research and Testing, a group of scientists develops NDTapplications based on GMR sensor technology. In particular, the knowledge gained in the field of automated testing systems based on the magnetic flux leakage (MFL) were combined with GMR sensors to achieve high resolution testing of ferromagnetic materials. In cooperation with Europe’s second lar...

Abstract During the last three decades, interest in application of steel shear walls has increased worldwide. Steel are used as stiffened and unstiffened walls. One main shortcomings plate wall (SPSW) is infill buckling mainly under lateral wind seismic loads. useful solutions to prevent use with corrugated plates. In this research, behavior a consisting two plates was investigated material cas...
