Seating Details for Precast Concrete Hollow-core and Flat Slab Floor Units Type 1 Support (Figures and ) The types of support for precast concrete hollow-core or flat slab flooring units seated on beams can be divided into the three groups as shown in Figure Where voided slab superstructures are used, the slab section shall be solid from the end of the slab to at least 1 ft. in front of the fascia. 9. The abutment shall be designed for a bearing pressure at service loads not to exceed TSF and a factored load at strength and extreme limit states not to exceed TSF.

Voided Slab Subjects Covered: Creating Voids, Continuous faces, Reinforcing faces, Manipulation of hook points Outline A hole can be created in a section by defining a second component, entirely contained within the first component and assigning it a “void” property.

The Standard Specifications for Highway Bridges are intended to serve as a standard or guide for the preparation of State specifications and for reference by bridge engineers. Primarily, the specifications set forth minimum requirements which are consistent with current practice, and certain modifications may be necessary to suit local conditions.   Long term monitoring of carbon composite strands in the Penobscot-Narrows bridge.. DOT National Transportation Integrated Search. The Penobscot-Narrows Bridge was constructed between May and December The bridge is a cable-stayed design with twin pylons and a 2,foot span. This cable-stayed bridge features a cradle stay system that: allows for .

A computer code for finite element analysis and design of post-tensioned voided slab bridge decks with orthotropic behaviour Article in Advances in Engineering Software July This is because, on account of the reduced area of tensile concrete, less premature internal failure (in the form of bond slip or internal cracking) occurs around a bar in a voided slab.

For spans of 30 to 35m or to ft the box will be economic where a depth of not less than m (4ft) is acceptable. For spans of 25 to 30m a prestressed concrete voided slab is the appropriate choice, changing to a reinforced concrete voided slab at some point between 25 and 20m or 80 and 65ft span.5/5(8).

The edition of the AASHTO book, A Policy on Geometric Design of Highways and Streets, recommends 16'-0" of clearance for highway bridges and 17'-0" for pedestrian bridges and sign bridges for freeways and arterials, a minimum clearance of 1'-0" above the legal vehicle height, and an allowance for future pavement resurfacing.

b) For curved bridges longer than feet, check the horizontal stopping sight distance and increase the inside shoulder width up to a maximum of 10'-0".

Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. It is often necessary in continuous slab bridges to make the centre span voided, as shown in Fig. in order to prevent uplift at the end supports under certain conditions of loading.

Voided slabs are gen era1ly used for spans of up to about 18 m and 25 m for reinforced and. The FHWA requires a TS&L study for tunnels, movable bridges, unusual structures, and major structures with deck areas greater thansquare feet.

This is a guideline only. Smaller bridges that are unusual may also require a TS&L study while some, such as long viaducts, may not.5/5(1).
