A Study on the Simulation of Construction Steps of Prestressed Concrete Bridges

P.C 교량의 시공단계 모사방법에 대한 연구

The changes of stuctural systems in constructing prestressed concrete bridges are investigated according to several construction methods. Based on these investigation, structurally meaningful works are summarized and defined as "Construction Commands". And time-dependent characteristics of concrete and prestressing steels are fully considered. For the static and/or dynamic analysis of three dimensional prestressed concrete bridges at ant construction stages, it is propoesd to use "Comstruction Commands" directly as user's input data. A example of cable syayed bridges is presented by the computer program developed by the present simulation method.
