Abstract
A significant increase of the intensity of road and urban transport requires new approaches to its improvement, especially in areas with dense existing buildings. The solution of this problem may be improving by building new bridges, road junctions and estokads The article is devoted to studies of deformation and crack resistance, proposed by the authors, constructive solution with double-beams continuous span bridge for complex construction conditions. There are important experimental results of research of bridge spans, with straight and curved parts with the different schemes and schemes of static load. The comparative calculation of experimental results and existing regulations is concluded. Due to proposed method for determining forces and deflections in double-beamed curvature bridges with continuous spans, the replacement with single-beamed constructions is proposed. The distribution of forces and deflections, in this case, might be determined by factors of distribution as for beams with different length. The factors of distribution are determined as the relation of areas limited by influence lines (in the case of distributed loading). In case of concentrated loading, the factors of distribution are determined as the relation of influence line`s ordinates sum for beams with different length.
