This paper presents special-purpose design program and plastic design results for hollow RC bridge columns with reinforcement details for material quantity reduction. The developed reinforcement details has economic feasibility and rationality and makes construction periods shorter. This study documents the economic evaluation of hollow reinforced concrete bridge column systems with reinforcement details for material quantity reduction and presents conclusions based on the application findings. As a result, the proposed reinforcement details for material quantity reduction were designed prior to the existing reinforcement details in terms of structural rationality, constructability, and economic. 이 연구에서는 물량저감 철근상세를 갖는 중공 철근콘크리트 교각 시스템의 전용 설계프로그램과 소성설계 적용 결과를 제시하였다. 개발된 물량저감 철근상세는 경제성과 합리성을 갖으며 공사기간의 단축을 가져올 수 있다. 물량저감 중공 철근콘크리트 교각의 적용을 통해 경제성 평가를 수행하였다. 평가 결과 개발상세가 기존상세에 비해 구조적 합리성, 시공성, 그리고 경제성 등이 우수함을 확인하였다.

Many bridges are severely damaged by the overloaded heavy vehicle and the trend will become more serious because the traffic volume is continuously increasing. Currently, the vehicles with gross weights over 40 tons or axle weight over 10 tons are not allowed on the public road. However, this regulation is not based on a systematic study on the bridge capacity and assumed to be much too conservative depending on the vehicle types and bridge types. In this study, the permit weights of heavy vehicles of diverse axle spacings and axle load distribution are calculated in the case of continuous bridges. In order to consider the various load effects of heavy weight vehicle crossings, three conditions are considered in the calculation of permit vehicle load. From the results, the permit vehicle weights of continuous bridges are calculated.
