Abstract

In recent years, bridges with precast beams have been designed as hyperstatic structures. Their support zones are usually shaped as monolithic continuous nodes, typically made of reinforced concrete. For this reason, estimation of internal forces in the connections is crucial. The forces arising from the force redistribution, which is related to the assembly technology and rheological effects, are particularly important. Precise methods of measuring these effects require computer implementation. However, in case of typical bridges, simplified procedures presented in the article can be applied.
