Proper support begins with the foundation, which is why it is important to carefully consider the type of support system you will use for your deck. Additionally, an unsupported deck can cause damage to the structure of your home or surrounding property. A deck that is not properly supported can sag, warp, or even collapse, putting the people using it at risk. Proper deck support is crucial for the safety and longevity of your deck.

Explanation of the importance of proper deck support.

But can you really use pier blocks instead of footings? In this article, we'll take a closer look at the pros and cons of using pier blocks versus footings, so you can make an informed decision for your deck building project. This includes quality control, construction operations, and wearing and protection systems.One option is to use deck pier blocks instead of footings. Part four provides information on the production, handling, and construction of full-depth precast deck panels. Part three provides examples of successful detailing including transverse joints, horizontal shear connection, leveling and temporary support, and haunch details between beam and deck. Specifics include design thickness, transverse and longitudinal reinforcement, overhang design, impact to barrier, panel-to-girder connection, and longitudinal post-tensioning.

Part two provides typical practice for design including transverse and longitudinal design along with design examples. It describes the system and shows the advantages of this system over the traditional CIP bridge deck. The first part is intended to provide an introduction to the relatively new technology of full-depth precast bridge deck panel system. The information is applicable for new bridge deck construction or bridge deck replacement. PCI has issued a complete report with the appendices providing state-of-the-art guidance relative to selecting, designing, detailing, and constructing precast full-depth decks for bridge construction. Shear connectors should be capable of resisting both horizontal and vertical movement between the concrete and the supporting system. Panel-to-Girder Connectionĭeck panels can be connected to supporting girders using either composite or non-composite connections. The strip method concept results in providing the main reinforcement in the transverse direction of the deck. The girders are considered rigid supports with no settlement.

The precast deck panel system is designed using the strip design method, where a transverse strip of the deck is analyzed as a continuous beam supported by the bridge girders. Generally, speed and economy are achieved with the use of the least number of panels.

Both the length and width are determined on a basis of handling and transportation.

The width of the panels is typically equal to the full width of the bridge. The length of the panel along the roadway is approximately 8 to 12 ft.

A full-depth precast deck employs a series of precast concrete panels that are full-depth in thickness-as required by structural design-with the length and width determined by specific bridge geometry.
