Abstract: In order to investigate the mechanisms and the factors to govern the brittle fracture initiation during the fatigue crack propagation at low temperatures, fracture toughness tests under wide ...

Abstract: This article deals with the effects of eccentricity on transmission errors of trochoidal gears (consisting of a roller gear and cam gear). For the tests, three types of roller gears and three ...

Abstract: Compressive crushing strength on brackish ice and sea ice and fracture toughness value on sea ice were measured as parameters associated with fracture strength of ice. The compressive crushing ...

Abstract: Most investigations dealing with research on shear focus on concrete members such as reinforced concrete (RC) and prestressed concrete (PC) beams, columns, and slabs. It is difficult for such investigations, which include ...

Abstract: In order to prevent traffic accidents on snow-covered bridge decks, the writers developed a new pipe heating system that uses only groundwater stored in a large underground tank. The underground tank provides geothermal ...

Abstract: This paper presents the negative bending of reinforced concrete slabs strengthened with near-surface mounted (NSM) carbon fiber-reinforced polymer (CFRP) strips. Six slab specimens, three of which are strengthened with ...

Abstract: This paper presents the behavior of a new composite deck system for twin-girder bridges subjected to moving-wheel fatigue load. The one-half scale system consists of a RC slab with transverse rib stiffeners welded to steel ...

Abstract: This paper presents an experimental study to develop a new composite slab system consisting of a concrete deck with reinforcing bars, steel plates welded with rib connectors, and a carbon fiber–blended cementitious adhesive. ...
