A MECHANICAL MODEL FOR THE RATIONAL DESIGN OF CRCP

Tatsuo NISHIZAWA, Saburo Matsuno, Tadashi Fukuda

Open publisher page 5 citations

Abstract

The design of CRCP can be roughly divided into the two parts. One is the design of steel reinforcement and the other the design of thickness of the concrete slab. The former is related to the transverse cracks due to temperature change and drying shrinkage. The latter is related to the structural response of CRCP to traffic loads. These two parts are interrelated with each other. This paper focuses on the structural response of CRCP to traffic loads. A mechanical model of CRCP by the use of finite element method will be described. In the model, a CRCP plate is divided into rectangular elements which consist of the strips of concrete plate between transverse cracks and the crack elements representing the transverse cracks. A CRCP constructed in Japan is analyzed by the model to verify the applicability of the model.
