[V-357] Rational Reinforcement Method for PC / PRC Structures Using 3D CAD Model

〇Yasushi Shimizu1, Noritaka Okada1 (1.JR East Consultants Company)

Keywords:Quality assurance, Rationalization of bar arrangement, 3D model

In order to improve the productivity and ensure the quality in the concrete work field, the application of the precast method and the efficiency of cast-in-place are mentioned.
As a method of rationalizing the arrangement and placement of reinforcing bars to ensure the quality, there is a method of ensuring the filling property of high-density reinforcing bars by using high and medium fluidity concrete.
This report is an effort on quality assurance by checking the interference between PC steel and reinforcement using a 3D CAD model at the design stage, and rationalizing the reinforcement when high-strength rebar is applied.
