{"Image DocumentName": "Bridge Engineering (6) Superstructure \u2013 Concrete Bridges", "Image ImageDescription": "Determination of concrete bridge superstructure: 1.1 the geometry of the bridge; 1.2 the span length; and. 1.3 the method of construction.  Bridge types and suitability. 2.1 Non pre-stressed concrete slab bridges The simplest type in which the deck slab also serves as the principal load carrying element The solid, cored, or ribbed concrete slab is supported directly on the substructure For spans below about 12m, a cast-in-place simple spans or continuous span solid slab may be used; and for spans over 12m, voided slabs become more economical Pre-cast slab decks usu. consist of a number of pre-cast voided slab sections placed side by side. 1 Wednesday, April 12, 2017.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
