RECONSTRUCTION OF BRIDGES USING METHOD OF LATERAL COMPRESSION OF SPAN STRUCTURES
Abstract
The paper considers a new technical solution of strengthening the existing assembly span structures made of T-beams with diaphragms with the help of lateral compression device. The peculiar feature of the solution consists in fixing the stressed elements for lateral compression not only in the place of edge beam ribs but also in the place of intermediate beam ribs. Due to this an effect of discrete bond between steel and concrete is ensured and it permits significantly to reduce tension force and increase efficiency of lateral compression for strengthening span structures. Technical and economical effect is achieved in the way when braces are located at the level of the bottom part of diaphragm section core that excludes emergence of tension stresses in the top part of diaphragm joints and ensures appearance of sufficient compressive stresses in the bottom part of diaphragm joints compensating tension against passing loads and this increases reliability of a span structure.
