INVESTIGATION INTO THE STATE OF REINFORCED CONCRETE STRUCTURES WITH REGARD TO THEIR SECURITY, USABILITY AND DURABILITY

ISTAZIVANJE STANJA PREDNAPREGNUTIH BETONSKIH KONSTRUKCIJA, S OBZIROM NA SIGURNOST, UPORABIVOST I TRAJNOST

Eight solid reinforced concrete bridges about 20 years old situated on regional roads were surveyed. Data were collected on the design, construction, testing and conditions of the bridges, based on visual observations and photographs. Cracks, carbonization, corrosion of the reinforcement, vibrations, quality of protective concrete layers and joints were studied. Besides the general survey of the structure, a survey of damages to the concrete (main girder, piles, diaphragm, bank supports) reinforcement and cable as well as other damages such as damages to the surfacing, parapet and gully, and erosion effects was carried out. Design, construction and maintenance defects which caused bridge damage were noticed after the analysis. It was also noticed that assumptions, the consequences of which cannot be realized during construction and maintenance, are used in designing of the structures. (TRRL)
