PARTIAL PREFABRICATION OF COMPOSITE PRESTRESSED AND REINFORCED CONCRETE SECTIONS FOR THE CONSTRUCTION OF SEWERS AND SMALL BRIDGES

PREFABRICACION PARCIAL EN SECCIONES MIXTAS DE HORMIGON PRECOMPRIMIDO Y ARMADO PARA LA CONSTRUCCION DE ALCONTARILLAS Y PUCNTES MENORES

Details are given of a type of cover consisting of precast elements shaped like an inverted t, which are pretensioned and linked by means of reinforcement concreted in-situ without hardly any formwork so as to form a composite, double-hinged slab frame. The design method for such structures is described, and examples are given of the calculation of a series of sewers, of 2,3 and 4 m span and of a height varying between 2, 3, 4 and 5 m, e.g., twelve different examples. A full-scale test carried out to study the structural behaviour of the prestressed and pretensioned concrete is also described. The values obtained (stresses, ultimate loads) showed that the structural behaviour is excellent. The number of the covering abstract is IRRD Abstract No. 100834. /TRRL/
