Abstract. Open channel conduit is commonly constructed on side roadway, car park area, etc., with the aims to collect rainwater or seapage water. To avoid garbages following the waterflow, the conduit is equipped with adequate cover. In addition, the cover can also be functioned for temporary car park area. Thus, the conduit cover should strong enough to sustain external loading. This paper discusses the design and response of the conduit cover using finite element software ANSYS MECHANICAL version 17.5.
